Transvaginal ultrasonography assessment of ovarian volumes in postmenopausal women.  

PubMed

The authors evaluated ovarian volumes by transvaginal ultrasonography at different periods after menopause. Ninety-eight postmenopausal women with an average age of 51.9 years and a one- to eight-year postmenopausal period were studied. The control group consisted of 40 women during menacme with an average age of 31.8 years, who were also submitted to transvaginal ultrasonography to evaluate ovarian volume. There was no significant difference between right and left ovarian volumes in the study groups. There was a significant decrease in measure and standard deviations of the volumes after the first year of menopause (mean volume--2.2 +/- 0.9 cm3) when compared to the control group (mean volume--6.3 +/- 2.0 cm3), followed by a slow and gradual shrinking after this phase. Decrease in ovarian volume became significant after the fourth postmenopausal year. Transvaginal ultrasonography demonstrated great importance as an investigative method of ovarian diseases in postmenopausal women. PMID:9181745

Transvaginal ultrasonography in first trimester of pregnancy and its comparison with transabdominal ultrasonography  

PubMed Central

Objectives: Examination of pregnant women in the first trimester with transvaginal ultrasonography with the aim to study various fetal development markers, e.g., gestation sac, yolk sac, fetal heart motion, CRL length, and fetal anatomy in both normal and abnormal pregnancies. Comparative evaluation of transvaginal ultrasonography vis-à-vis transabdominal scanning in the study of first trimester of pregnancy and its complications. To assess the relative merits and demerits of transvaginal ultrasonography in comparison with the transabdominal technique. Materials and Methods: The study will be conducted on 50 females patients during the first trimester of pregnancy. The study population will consist of both normal and abnormal pregnancies. These patients will be included on the basis of suspicion of or proven pregnancy of duration up to 12 weeks from LMP. The evaluation of the patients will include the following: Record of patients obstetrical history and clinical examination, record of pregnancy test and relevant investigations, ultrasonic examination of pregnancy. (a) Transabdominal ultrasound scanning will be done with moderately distended bladder by using real time scanners with low frequency probe (3/3.5 MHz); (b) transvaginal sonography will be done with the real-time sector scanner using high-frequency endovaginal probe (5/7.5 MHz), after the patient voids urine. Relevant images will be taken by using the multiformat automatic camera. Results and Conclusions: In the study of 46 normal intrauterine pregnancies, TVS showed additional information in 36 patients (78.3%) as compared to TAS, in detection of gestation sac, yolk sac, double bleb sign, or better visualization of embryonic anatomy. In the abnormal pregnancy (n=17), TVS provided more information in 11 cases (64.9%), which included detection of embryonic demise, yolk sac, double bleb sign, or subchorionic hemorrhage. Regarding ectopic gestations (n=7), TVS gave additional information in 5 cases (71.4%) which included detection of ectopic fetal pole, yolk sac, decidual cast, adnexal mass, and fluid in cul de sac. In two cases, both TAS and TVS gave equal information. However, in 2 cases TAS demonstrated the extent of intraabdominal fluid better than TVS. The other advantages of TVS over TAS are that there is no need for the patient to have uncomfortably full bladder and time is saved from having to wait for bladder to fill. Thus, the potential preoperative patient can be kept fasting. TVS is also superior in obese patients, in patients with retroverted uterus and it also bypasses obstacles such as bone, gas filled bowel, and extensive pelvic adhesions. The limitations encountered with TVS were limited manoveuribility of probe and because of the unorthodox position and angle of the transducer, correct orientation was difficult initially.

Biomedical applications of ovarian transvaginal ultrasonography in cattle.  

PubMed

Ovarian transvaginal ultrasonography (OTU) has been used world-wide for commercial ovum pick-up programs for in vitro embryo production in elite herds, providing an excellent model for the elucidation of factors controlling bovine oocyte developmental competence. Noninvasive sampling and treatment of ovarian structures is easily accomplished with bovine OTU techniques providing a promising system for in vivo delivery of transgenes directly into the ovary. The current review summarizes existing bovine OTU models and provides prospective applications of bovine OTU to undertake research in reproductive topics of biomedical relevance, with special emphasis on the development of in vivo gene transfer strategies.

Transvaginal ultrasonography in ovarian cancer screening: current perspectives.  

PubMed

Transvaginal ultrasonography (TVS) is an integral part of all major ovarian cancer screening trials. TVS is accurate in detecting abnormalities in ovarian volume and morphology, but is less reliable in differentiating benign from malignant ovarian tumors. When used as the only screening test, TVS is sensitive, but has a low positive predictive value. Therefore, serum biomarkers and tumor morphology indexing are used together with TVS to identify ovarian tumors at high risk for malignancy. This allows preoperative triage of high-risk cases to major cancer centers for therapy while decreasing unnecessary surgery for benign disease. Ovarian cancer screening has been associated with a decrease in stage at detection in most trials, thereby allowing treatment to be initiated when the disease is most curable. PMID:24379701

[Transvaginal ultrasonography and nuclear magnetic resonance. Comparison of techniques in the evaluation of ovarian lesions].  

PubMed

A total of 53 patients were included in this study, aged between 21 and 72 years old and hospitalised with the diagnosis of ovarian tumour. All patients underwent a clinical examination, ultrasonography and NMR prior to surgery. The findings of ultrasonography and NMR were correlated with histological results in order to evaluate the value of these methods in the differential diagnosis of benign and malignant ovarian tumours. Histological tests revealed 46 benign tumours, 3 borderline cases and 4 malignant growths. Transvaginal ultrasonography revealed precisely 47 out of 53 ovarian tumours, and NMR 49 out of 53. The main limitation of both techniques was the tendency to overestimate ovarian lesions (specificity: ultrasonography 89%, NMR 93%). As far as concerns the identification of malignant lesions NMR does not appear to offer significant advantages in comparison to ultrasonography (sensitivity 85% ultrasonography = NMR). PMID:7854561

Transvaginal ultrasonography and uterine artery Doppler in diagnosing endometrial pathologies and carcinoma in postmenopausal bleeding.  

PubMed

Routine dilatation and curettage (D&C) in all patients with postmenopausal bleeding (PMB) is debatable, as 70%-80% will eventually receive benign diagnoses. Endometrial thickness (ET) measurements by transvaginal ultrasonography (TVUS) are used with high sensitivity to detect patients who would benefit from D&C, yet they suffer from low specificity that fails to reduce undue invasive procedures. The aim of this study was to define optimal cutoffs for ET in diagnosing endometrial pathologies in PMB and to assess a possible complementary role for Doppler ultrasonography. The study population consisted of 97 women with PMB; 39, 22 and 36 of whom had endometrial cancer (EC), benign endometrial pathologies and normal endometrial findings, respectively, defined by D&C performed after TVUS, which was used to measure uterine dimensions and ET, together with pulsatility and resistance indices (PI and RI, respectively) of the uterine arteries. Receiver operating characteristics curves revealed ET to be the most valuable parameter to prognosticate both EC and any endometrial pathology (sensitivities of 90% and 89%, and specificities of 79% and 94% with optimal cutoffs of 9.6 and 7.7 mm, respectively). Binary logistic regression revealed uterine artery RI to be the only independent variable that could be used together with ET, which increased the sensitivity of ET to 97% and 93% for EC and any endometrial pathology, but caused its specificity to regress to 58% and 53%, respectively. Same levels of sensitivity, yet better levels of specificity of 60% and 89%, respectively, were attained by using a cutoff of 6.3 mm for ET alone. Assessing uterine artery Doppler indices has no complementary role for measuring ET in evaluating PMB. PMID:12942246

Comparison of Transvaginal Ultrasonography with Hysterosonography as a Screening Method in Patients with Abnormal Uterine Bleeding  

PubMed Central

Objective To assess the utility of hysterosonography (HS) as a screening method in patients with abnormal uterine bleeding. Materials and Methods We retrospectively reviewed transvaginal ultrasonography (TVS) and HS for 105 patients whose diagnosis was confirmed pathologically. All 105 patients were initially evaluated on the same day with both TVS and HS. On TVS and HS examination, endometrial cavitary lesions were classified as diffuse hyperplasia, endometrial polyp, endometrial cancer, uterine synechia and submucosal leiomyoma. Hysteroscopy with biopsy (n=35), curettage (n=60) or hysterectomy (n=10) was performed, and the results of TVS and HS examination were correlated with the pathological findings. Results The sensitivity and specificity were 79.0% and 45.8% for TVS, and 95.1% and 83.3% for HS, respectively. The positive and negative predictive values were 83.0% and 39.3% for TVS, and 95.1% and 83.3% for HS, respectively. Twenty-seven showed a discrepancy between the TVS and HS, and eight cases showed a discrepancy between HS and the pathologic diagnosis. Conclusion TVS is a sensitive method to evaluate the endometrial cavitary lesions, but it often does not provide the physician with sufficient diagnostic information. With its higher sensitivities, specificities and positive and negative predictive values, HS can be better used than TVS in evaluating those patients with abnormal uterine bleeding.

Comparison of transvaginal ultrasonography and hysteroscopy in the diagnosis of uterine pathologies  

PubMed Central

A thorough evaluation of the uterine cavity is frequently required in gynecology practice. The aim of this study was to compare the diagnostic values of transvaginal ultrasound examination and hysteroscopy in detecting uterine abnormalities in a group of patients within a range of menopausal status and symptomatology. This study included 285 patients admitted with complaints of abnormal uterine bleeding, postmenopausal bleeding, lower abdominal pain, abnormal vaginal discharge or for a routine gynecological examination. All patients had available transvaginal ultrasonography and hysteroscopy data for evaluation. A biopsy was obtained from all patients during the hysteroscopy session. Sensitivity, specificity, positive predictive value, negative predictive value and likelihood ratio were calculated for both methods and compared, considering the histopathological diagnosis as the gold standard. The mean age of the patients was 49.5±12.9 years (range, 24-89 y). Majority of the patients admitted for abnormal uterine bleeding (n=198, 69.4%). For the diagnosis of polyps of any size, hysteroscopy had better sensitivity (p<0.001), however, specificities did not differ (p=1.0). On the other hand, hysteroscopy did not have a sensitivity advantage over TVU in diagnosing polyps greater than 1 cm (p=0.077), although this time hysteroscopy had better specificity (p<0.001). Combined approach did not offer diagnostic advantage for any of the specific pathologies. Although TVU represents a practical approach for the initial evaluation of uterine pathologies, hysteroscopy seems to offer better diagnostic value for uterine pathologies in general, and uterine polyps in particular.

Cervical Length Measured by Transvaginal Ultrasonography and Cervicovaginal Infection as Predictor of Preterm Birth Risk  

PubMed Central

Introduction: The study shows possibilities of transvaginal sonographic measurement of the cervix in prediction of premature birth risk. Goals: The aim of the study was to follow up the cervical length in the pregnant from 16th to 37th week, as well as to do a microbiological analysis of the vaginal and cervical flora and to identify relation between the cervical shortening and microbiological flora as well as with a premature birth. Material and methods: The investigation was conducted as a prospective study on two groups of female patients in Clinical Centre of Banja Luka. In the high risk group we had 8% of patients with cervical length bellow than 15mm, 30% of patients with cervical length from 15 to 25m and 62% of patients with cervical length bigger than 25mm. In the low risk group we had no patients with cervical length bellow 15mm, 95% of patients had cervical length bigger than 25mm and 5% of patients had cervical length from 15 do 25mm. Results: The regression coefficient of the cervical length in the high risk group was 0.44mm, while in the low risk group it was 0.26mm. In the high risk group 67.56% patients had a positive cervical smear finding, while in the low risk group it was 4%. A high premature birth (defined as birth before 36.6 weeks) incidence of 50% was presented in patients with cervical length bellow 15mm. In the group of patients with cervical length up to 25mm the premature risk incidence was 10.52±0.05. In the high risk group of patients with a positive cervical smear finding, regarding the cervical length the percentage was as follows; in the subgroup of 15mm length 88,89±11,87, in subgroup from 15 to 25mm was 62,07±11,43 and in the subgroup bigger than 25mm, 60.06±8.05. Conclusion: By the analysis of the first and second goal of our study we can conclude that ultrasound assessment of cervical length is simple and feasible in the 16th week of pregnancy in both groups, with high and low risk. The length of the cervix in this period is shorter in the high risk group compared with the low-risk group. This difference was not statistically significant, however, it clearly demonstrated connection between shorten length of the cervix with the preterm birth. A regression analysis shows that the shortening of the cervix length is more frequent in high risk group which is to be expected, bearing in mind that in this group, the risk of preterm delivery was significantly higher.

Transrectal ultrasonography in the assessment of congenital vaginal canalization defects.  

PubMed

Our aim was to evaluate the reliability of transrectal ultrasonography in the preoperative assessment of congenital vaginal canalization defects. We studied nine patients, six with suspected Rokitansky syndrome and three with suspected complete transverse septum. Before corrective surgery all the patients underwent pelvic examination, transabdominal and transrectal ultrasonography. The ultrasonographic findings were compared with the surgical ones. Transrectal ultrasonography provided an accurate map of the pelvic organs showing the precise distances between the urethra and bladder anteriorly, rectum posteriorly, retrohymenal fovea caudally, and pelvic peritoneum cranially. Transrectal ultrasonography produced a picture that corresponded perfectly with the real anatomical situation. Conversely, abdominal ultrasonography provided inadequate images in six of our nine patients, and magnetic resonance imaging was responsible for a mistaken diagnosis in one patient with suspected transverse vaginal septum. In conclusion, if our results are confirmed in larger series, transrectal ultrasonography could be considered as a diagnostic procedure of choice in the assessment of vaginal canalization defects.

[Contribution of ultrasonography for the preoperative assessment of gastric contents].  

PubMed

The assessment of the risk of pulmonary aspiration of gastric contents may be difficult in the preoperative period, apart from typical circumstances. The development of ultrasonography in anesthesia and critical care has led to consider ultrasonic imaging of gastric contents for preoperative risk assessment of "full" stomach in clinical practice. Ultrasonography of the body of the stomach allows direct visualization of the gastric contents. However, the stomach is often difficult to identify, particularly when it is empty. Moreover, quantitative assessment of gastric volume is delicate, and no standardized method of ultrasonography of the body of the stomach for preoperative assessment of gastric contents was described. On the contrary, ultrasonography of the antral cross-sectional area, which was initially described for the assessment of gastric emptying as an alternative method to repeated measurements of the variations of antropyloric volume after ingestion of a test meal, is easy to perform and is highly reproducible through using the aorta and the left lobe of the liver as internal landmarks. Qualitative assessment of the gastric antrum allows easily diagnosis of a "full" stomach. The measurement of antral area may allow a more accurate estimate of the presence or absence of gastric contents at risk of lung injury in the event of regurgitation and aspiration (gastric volume >0.8 ml/kg and/or with solid particles), defining the "risk" stomach. The use of antral ultrasonography may help the anesthesiologist to assess the risk of pulmonary aspiration according to clinical history of the patient, in order to choose an appropriate strategy minimizing the occurrence of this complication.

MRI versus Ultrasonography to Assess Meniscal Abnormalities in Acute Knees.  

PubMed

While magnetic resonance imaging (MRI) is often considered the "gold standard" diagnostic imaging modality for detection of meniscal abnormalities, it is associated with misdiagnosis in as high as 47% of cases, is costly, and is not readily available to a large number of patients. Ultrasonographic examination of the knee has been reported to be an effective diagnostic tool for this purpose with the potential to overcome many of the shortcomings of MRI. The purpose of this study is to determine the clinical usefulness of ultrasonography for diagnosis of meniscal pathology in patients with acute knee pain and compare its diagnostic accuracy to MRI in a clinical setting. With Institutional Review Board approval, patients (n?=?71) with acute knee pain were prospectively enrolled with informed consent. Preoperative MRI (1.5 T) was performed on each affected knee using the hospital's standard equipment and protocols and read by faculty radiologists trained in musculoskeletal MRI. Ultrasonographic assessments of each affected knee were performed by one of two faculty members trained in musculoskeletal ultrasonography using a 10 to 14?MHz linear transducer. Arthroscopic evaluation of affected knees was performed by one of three faculty orthopedic surgeons to assess and record all joint pathology, which served as the reference standard for determining presence, type, and severity of meniscal pathology. All evaluators for each diagnostic modality were blinded to all other data. Data were collected and compared by a separate investigator to determine sensitivity (Sn), specificity (Sp), positive predictive value (PPV), negative predictive value (NPV), correct classification rate (CCR), likelihood ratios (LR[+] and LR[-]), and odds ratios. Preoperative ultrasonographic assessment of meniscal pathology was associated with Sn?=?91.2%, Sp?=?84.2%, PPV?=?94.5%, NPV?=?76.2%, CCR?=?89.5%, LR(+)?=?5.78, and LR(-)?=?0.10. Preoperative MRI assessment of meniscal pathology was associated with Sn?=?91.7%, Sp?=?66.7%, PPV?=?84.6%, NPV?=?80.0%, CCR?=?81.1%, LR(+)?=?2.75, and LR(-)?=?0.13. Ultrasonography was two times more likely than MRI to correctly determine presence or absence of meniscal pathology seen arthroscopically in this study. Ultrasonography is a useful tool for diagnosis of meniscal pathology with potential advantages over MRI. Based on these data and available portable equipment, ultrasonography could be considered for use as a point-of-injury diagnostic modality for meniscal injuries. PMID:24474166

Screening of preterm labor in Yazd city: transvaginal ultrasound assessment of the length of cervix in the second trimester  

PubMed Central

Background: Spontaneous preterm labor is one of the common obstetrics problems causing several physical, psychological and economical outcomes. Although due to these outcomes and the efficacy of cares for decreasing them, preterm labor screening is cost-effective and it is still one of the challenging issues in obstetrics. Objective: In this study preterm labor screening by using cervical transvaginal sonography was evaluated. Materials and Methods: This observational cohort study was performed in Yazd, Iran. Samples were selected from pregnant women at gestational age of 21-24 weeks who had single live fetus and referred to the obstetrics clinics of two selected hospitals in Yazd. Gestational age was estimated based on the sonography of the first trimester and cervical length measured by transvaginal sonography. Data analysis was done by using t and x2 test as well as ANOVA. Statistical significant level was considered as p<0.05. Results: From 450 participants, 47 cases had preterm labor and 6 cases had positive funneling. Mean age of women with term labor was 26.09±4.13 years and that of women with preterm labor was 26.7±3.51 years (p=0.334). Duration of pregnancy and cervical length significantly differed between women with and without funneling (p=0.001). The sensitivity and specificity of screening based on cervical length of 25mm were 55.5% (50.9-60.1%) and 93.6% (91.2-96%) respectively. Conclusion: Based on the results of the present study, transvaginal ultrasound assessment of cervical length in low risk women has an acceptable reliability for screening of preterm labor.

Transvaginal hydrolaparoscopy.  

PubMed

Transvaginal hydrolaparoscopy (THL) is being performed regularly in Europe and China, but rarely in the United States. The reasons may be physicians' unfamiliarity with the procedure and their uneasiness over potential rectal puncturing due to the proximity of the rectum to the vaginal trocar insertion site. THL has the advantage over hysterosalpingography (HSG) in that it allows for direct visualization of the tubal mucosa in addition to determining tubal patency. THL has advantages over traditional laparoscopy in that it does not require an abdominal incision and has the capability of being conducted in an outpatient office setting with local anesthesia. Studies have shown that THL has comparable accuracy to laparoscopy with 96.1% concordance between THL and laparoscopic findings. THL may be combined with chromopertubation and salpingoscopy. In addition to diagnostic purposes, THL may be used for operative intervention including adhesiolysis, endometriosis ablation, and ovarian drilling. Studies from France and China report the occurrence of rectal injury from 0% to1%. Despite the advantages of THL and low reports of rectal injury, THL has not gained popularity in the United States. The purpose of this article is to familiarize gynecologists in the United States with THL. PMID:23318074

Duplex Ultrasonography in Assessing Restenosis of Renal Artery Stents  

SciTech Connect

Purpose: To determine the accuracy and optimal threshold values of duplex ultrasonography (US) in assessing restenosis of renal artery stents. Methods: Twenty-four consecutive patients with 33 renal arteries that had previously been treated with placement of a Palmaz stent underwent duplex US prior to intraarterial digital subtraction angiography (DSA), which was the reference standard. Diagnostic accuracy of in-stent peak systolic velocity (PSV) and reno-aortic ratio (RAR = PSV renal stent/PSV aorta) in detecting > 50% in-stent restenosis were evaluated by the receiver operating characteristic curve. Sensitivity and specificity were determined using the optimal threshold values, and using published threshold values: RAR > 3.5 and in-stent PSV > 180 cm/sec. Results: Six examinations were technically inadequate. Nine stents had residual or restenosis > 50% at DSA. The two duplex parameters were equally accurate since areas under the curves were similar (0.943). With optimal threshold values of 226 cm/sec for PSV and 2.7 for RAR, sensitivities and specificities were 100% and 90%, and 100% and 84%, respectively. Using the published duplex criteria resulted in sensitivities and specificities of 100% and 74% for PSV, and 50% and 89% for RAR. Conclusion: Duplex US is a sensitive modality for detecting in-stent restenosis if laboratory-specific threshold values are used.

Evaluation of the accuracy of transvaginal sonography for the assessment of retained products of conception after spontaneous abortion.  

PubMed

Transvaginal sonography (TVS) was used to assess uterine contents in 100 consecutive subjects presenting with a diagnosis of spontaneous abortion. TVS assessments were correlated with findings at subsequent evacuation of retained products of conception (ERPC). There was a strong correlation between the weight of the surgical specimen at ERPC with both the sagittal (r = 0.76; p < 0.05) and transverse (r = 0.73; p < 0.05) plane area measurements of the uterine cavity. Combining the 2 sonographic measurements increased the correlation to r = 0.81 (p < 0.05). Fifteen of 25 subjects who had been categorised to have an 'empty' uterus had less than 5 g of tissue removed and the other 10 subjects less than 10 g of tissue. In 20 of these 25 cases, the surgeon described the amount of curettings as 'small or non-significant'. TVS can accurately identify those women who do not have a significant amount of residual uterine tissue following spontaneous abortion. PMID:9565145

Concordance between hip ultrasonography and hip arthrography in the assessment of developmental dysplasia of the hip.  

PubMed

Controversy exists regarding the possibility of predicting hip reducibility in the congenitally dislocated hip, with arthrography still regarded as the gold standard in this situation. This study aims at assessing the degree of concordance between ultrasonography and arthrography in the detection of anatomic elements obstructing hip reduction. Forty-nine hips were studied both by ultrasonography and arthrography. Three anatomic sources of obstruction to reduction were assessed in each hip: ligamentum teres hypertrophy, inverted labrum, and the presence of soft tissue in the acetabulum. For each variable, congruence between ultrasound and arthrography was measured by kappa analysis. Values > 0.40 expressed sufficient concordance, and they were detected with regard to inverted labrum and the presence of soft tissue in the acetabulum. The results of this study suggest that ultrasonography may be considered a reliable technique for the prediction of the main causes of obstruction in the congenitally dislocated hip, such as inverted labrum and soft tissue in the acetabulum.

Diagnostic endoscopic ultrasonography: Assessment of safety and prevention of complications  

PubMed Central

Endoscopic ultrasonography (EUS) has gained wide acceptance as an important, minimally invasive diagnostic tool in gastroenterology, pulmonology, visceral surgery and oncology. This review focuses on data regarding risks and complications of non-interventional diagnostic EUS and EUS-guided fine-needle biopsy (EUS-FNB). Measures to improve the safety of EUS und EUS-FNB will be discussed. Due to the specific mechanical properties of echoendoscopes in EUS, there is a low but noteworthy risk of perforation. To minimize this risk, endoscopists should be familiar with the specific features of their equipment and their patients’ specific anatomical situations (e.g., tumor stenosis, diverticula). Most diagnostic EUS complications occur during EUS-FNB. Pain, acute pancreatitis, infection and bleeding are the primary adverse effects, occurring in 1% to 2% of patients. Only a few cases of needle tract seeding and peritoneal dissemination have been reported. The mortality associated with EUS and EUS-FNB is 0.02%. The risks associated with EUS-FNB are affected by endoscopist experience and target lesion. EUS-FNB of cystic lesions is associated with an increased risk of infection and hemorrhage. Peri-interventional antibiotics are recommended to prevent cyst infection. Adequate education and training, as well consideration of contraindications, are essential to minimize the risks of EUS and EUS-FNB. Restricting EUS-FNB only to patients in whom the cytopathological results may be expected to change the course of management is the best way of reducing the number of complications.

Assessment of fetal behavior using four-dimensional ultrasonography: current knowledge and perspectives.  

PubMed

In the last decades, the development of real-time ultrasonography has allowed the direct view of the fetus in the uterus, as well as assessing its activity. The advent of three-dimensional ultrasonography (3D) at the end of the 80s initiated a new era in diagnostic imaging for Obstetrics, dramatically increasing the possibility of studying the fetus. Recently, a new technique allowing the 3D image to be transformed into real-time was introduced: the four-dimensional (4D) ultrasonography. It allows the continuous monitoring of fetal face and other surface areas, such as the extremities. Some studies have already assessed this new methodology for fetal behavior observation during different stages of pregnancy, trying to understand better the relationship between fetal central nervous system maturation and the implications for its behavior. In this article, the authors review the current use of 4D ultrasonography in the assessment of fetal behavior, and discuss the possibilities of the technique to show the neurological development of the fetus, by means of watching movement and facial expressions. They also highlight the potential applicability of this new method in this new research area of fetal medicine. PMID:24007875

Reproducibility of ultrasonography for assessing abdominal fat distribution in a population at high risk of diabetes  

PubMed Central

Background: Visceral fat plays an important role in the development of metabolic disease independently of the effect of overall abdominal fat. Ultrasonography is an accessible method of accurately assessing abdominal fat distribution in epidemiological studies, but few details about the reproducibility of this method have been published. Objective: The aim of this study was to investigate the reproducibility of ultrasonography in the assessment of abdominal fat distribution in a population at high risk of type 2 diabetes. Design and Methods: Ultrasonography was used to estimate visceral and subcutaneous abdominal fat. Intra- and interobserver variation, short-term variation and variation between estimates in the fasting and non-fasting state were examined in three samples of 30, 33 and 23 participants from the ADDITION-PRO study. A variance components model was used to calculate intra- and interobserver variation, and Bland–Altman plots were drawn for all three substudies. Results: Coefficients of variation for intra- and interobserver variation were in the range 3.4–6.1%, except for interobserver variation for subcutaneous fat (9.5%). Short-term variation over a median of 35 days had a coefficient of variation of 15%. The effect of a meal was primarily on the visceral estimates and did not extend beyond the first postprandial hour. Non-fasting visceral estimates were larger than fasting estimates. Conclusion: Both visceral and subcutaneous fat can be estimated with ultrasonography with adequate intra- and interobserver reproducibility by clinical researchers with limited training, making it a feasible method of assessing abdominal fat distribution in epidemiological studies.

Severity of Carpal tunnel syndrome assessed with high frequency ultrasonography.  

PubMed

Although nerve conduction study (NCS) is the method most frequently used in daily clinical practice to confirm clinical diagnosis of Carpal tunnel syndrome (CTS), ultrasonographic (US) measurement of the median nerve cross-sectional area is both sensitive and specific for the diagnosis of CTS. Moreover, an algorithm evaluating CTS severity based on CSA of median nerve was suggested. This study is aimed to investigate the clinical usefulness of this algorithm in assessing CTS severity. The patients underwent a full clinical examination, including Tinel and Phalen test, and questioned about symptoms and the secondary causes of CTS. All of the patients refilled a Turkish version Levine Boston Carpal tunnel syndrome questionnaire (BQ) and the visual analog scale for pain (VAS 0-100 mm) A MyLab 70 US system (Esaote Biomedica, Genoa, Italy) equipped with a broadband 6-18 MHz linear transducer was used for US examination. The cross-sectional area of the median nerve was measured at the proximal inlet of the carpal tunnel (US cut-off points that discriminate between different grades of CTS severity as 10.0-13.0 mm(2) for mild symptoms, 13.0-15.0 mm(2) moderate symptoms and >15.0 mm(2) for severe patients). Nerve conduction studies were carried out, and severity of electrophysiological CTS impairment was reported as normal, mild, moderate, severe and extreme. The agreement between NCS and US in showing CTS severity (normal, mild, moderate and severe) was calculated with Cohen's kappa coefficient. Ninety-nine wrists of 54 patients (male/female: 4/50) were included in the study. Mean ages of patients were (+/-SD) 43.3 +/- 11 years. Forty-nine patients had idiopathic CTS, whereas five had secondary CTS (4 had diabetes mellitus and 1 had hypothyroidism). Symptoms were bilateral in 45 patients (83.3%). There were statistical differences between the groups according to electrophysiologic severity scale in terms of age (P < 0.001), body-mass index (P = 0.034), VAS (P = 0.014), Boston symptom severity (P = 0.013) and CSA of median nerve (P < 0.001). The identification of CTS severity showed substantial agreement (Cohen's kappa coefficient = 0.619) between the US and NCS. Also the four groups based on US CTS severity classification were significantly different in VAS (P = 0.017) and Boston symptom severity (P = 0.021). The median nerve swelling detected by calculation of the CSA reflects in itself the degree of nerve damage as expressed by the clinical picture. In addition to CTS diagnosis, sonographic measurement of CSA could also give additional information about severity of median nerve involvement. Using of US may cost-effectively reduce the number of NCS in patients with suspected CTS. PMID:19593567

Ultrasonography assessment of vocal cords mobility in children after cardiac surgery  

PubMed Central

Objectives Upper airway obstruction after pediatric cardiac surgery is not uncommon. In the cardiac surgical population, an important etiology is vocal cord paresis or paralysis following extubation. In this study, we aimed to evaluate the feasibility and accuracy of ultrasonography (US) assessment of the vocal cords mobility and compare it to fiber-optic laryngoscope (FL). Material and methods A prospective pilot study has been conducted in Pediatric Cardiac ICU (PCICU) at King Abdulaziz Cardiac Center (KACC) from the 1st of June 2009 till the end of July 2010. Patients who had cardiac surgery manifested with significant signs of upper airway obstruction were included. Each procedure was performed by different operators who were blinded to each other report. Results of invasive (FL) and non-invasive ultrasonography (US) investigations were compared. Results Ten patients developed persistent significant upper airway obstruction after cardiac surgery were included in the study. Their mean ± SEM of weight and age were 4.6 ± 0.4 kg and 126.4 ± 51.4 days, respectively. All patients were referred to bedside US screening for vocal cord mobility. The results of US were compared subsequently with FL findings. Results were identical in nine (90%) patients and partially different in one (10%). Six patients showed abnormal glottal movement while the other four patients demonstrated normal vocal cords mobility by FL. Sensitivity of US was 100% and specificity of 80%. Conclusion US assessment of vocal cord is simple, non-invasive and reliable tool to assess vocal cords mobility in the critical care settings. This screening tool requires skills that can be easily obtained.

Using functional transcranial Doppler ultrasonography to assess language lateralisation: Influence of task and difficulty level  

PubMed Central

Language is lateralised to the left hemisphere in most people, but it is unclear whether the same degree and direction of lateralisation is found for all verbal tasks and whether laterality is affected by task difficulty. We used functional transcranial Doppler ultrasonography (fTCD) to assess the lateralisation of language processing in 27 young adults using three tasks: word generation (WG), auditory naming (AN), and picture story (PS). WG and AN are active tasks requiring behavioural responses whereas PS is a passive task that involves listening to an auditory story accompanied by pictures. We also examined the effect of task difficulty by a post hoc behavioural categorisation of trials in the WG task and a word frequency manipulation in the AN task. fTCD was used to measure task-dependent blood flow velocity changes in the left and right middle cerebral arteries. All of these tasks were significantly left lateralised: WG, 77% of individuals left, 5% right; AN, 72% left: 4% right; PS, 56% left: 0% right. There were significant positive relationships between WG and AN (r = 0.56) as well as AN and PS (r = .76) but not WG and PS (r = ?0.22). The task difficulty manipulation affected accuracy in both WG and AN tasks, as well as reaction time in the AN task, but did not significantly influence laterality indices in either task. It is concluded that verbal tasks are not interchangeable when assessing cerebral lateralisation, but that differences between tasks are not a consequence of task difficulty.

Longitudinal assessment of bone quality by quantitative ultrasonography in children and adolescents.  

PubMed

Among the techniques available to assess bone quality, quantitative ultrasonography of the proximal phalanges of the hand (QUS) has emerged as particularly attractive. In this study, amplitude-dependent speed of sound (AD-SoS) and bone transmission time (BTT) were obtained by the sonographic device DBM Sonic BP IGEA in two sessions at two years' interval, in a school-age population (589 subjects, 290 mol/L and 299F, aged 3 to 16 y) with the aim to determine accuracy of QUS measurements, evaluate QUS variable changes during growth, relate these values with age and growth variables. Mean AD-SoS and BTT at age classes from 5 to 12 y as determined at the first and second measurement sessions were not significantly different. A significant increment (p < 0.0001) between the first and the second measurement was observed for both QUS variables. AD-SoS and BTT showed significantly different variations in the various age groups (ANOVA). Correlations were found of AD-SoS and BTT increments with age, height, weight, pubertal stage and with height growth velocity (p < 0.05). AD-SoS and BTT increment curves presented a very similar trend decreasing from 4 to 7 y of age. Thereafter a plateau was reached up to the age of 10 to 11 y in girls and 11 to 12 y in boys, when an increase was observed corresponding to pubertal growth rate acceleration. In conclusion, the present study would confirm that QUS measurements are accurate. Ad-SoS and BTT increment models are similar to most growth velocity curves and follow a strongly age- and growth-dependent pattern. PMID:16829314

Diagnostic Accuracy of Transvaginal Sonography in the Detection of Uterine Abnormalities in Infertile Women  

PubMed Central

Background Accurate diagnosis of uterine abnormalities has become a core part of the fertility work-up. A variety of modalities can be used for the diagnosis of uterine abnormalities. Objectives This study was designed to assess the diagnostic accuracy of transvaginal ultrasonography (TVS) in uterine pathologies of infertile patients using hysteroscopy as the gold standard. Patients and Methods This was a cross-sectional study carried out in the Department of Reproductive Imaging at Royan Institute from October 2007 to October 2008. In this study, the medical documents of 719 infertile women who were investigated with transvaginal ultrasound (TVS) and then hysteroscopy were reviewed. All women underwent hysteroscopy in the same cycle time after TVS. Seventy-six out of 719 patients were excluded from the study and 643 patients were studied. TVS was performed in the follicular phase after cessation of bleeding. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were calculated for TVS. Hysteroscopy served as the gold standard. Results The overall sensitivity, specificity, positive and negative predictive values for TVS in the diagnosis of uterine abnormality was 79%, 82%, 84% and 71%, respectively. The sensitivity and PPV of TVS in detection of polyp were 88.3% and 81.6%, respectively. These indices were 89.2% and 92.5%, respectively for fibroma, 67% and 98.3%, respectively for subseptated uterus and 90.9% and 100%, respectively for septated uterus. Adhesion and unicornuated uterus have the lowest sensitivity with a sensitivity of 35% and PPV of 57.1%. Conclusion TVS is a cost-effective and non-invasive method for diagnosis of intrauterine lesions such as polyps, submucosal fibroids and septum. It is a valuable adjunctive to hysteroscopy with high accuracy for identification and characterization of intrauterine abnormalities. This may lead to a more precise surgery plan and performance.

Assessment of TMJ Disorders Using Ultrasonography as a Diagnostic Tool: A Review.  

PubMed

Temporomandibular disorders affect nearly 10-70% of population. Hence, a proper diagnosis of temporomandibular disorders using appropriate diagnostic aids is required. Thus, the purpose of this review was to check the use of ultrasonography as a diagnostic aid in the detection of TMJ disorders.A literature review was performed in Pub Med Central and Cochrane library using Mesh Terms - 'ultrasonography' and 'TMJ disorders'. Out of the total 113 titles appeared, 38 were related to the research question. Further search criteria were applied to the articles, out of which 11 articles fulfilled the criteria and were selected for the review. Two articles which were hand searched were also included. Sensitivity of ultrasonography in detecting TMJ disorders in a majority of articles ranged from 41%-90% in disc displacement, when MRI was taken as the gold standard. In case of TMJ Effusion and Condylar effusion, sensitivities ranged from 20-80% and 83% respectively. It was also seen that sensitivity increased with increase in frequency of transducer. In the available literature, it was found that ultrasonography was an acceptable diagnostic tool for detection of disc displacement, condylar erosion and articular effusion. PMID:24551747

Hybrid transvaginal incisional hernia repair.  

PubMed

Abstract Aim: Natural orifice translumenal endoscopic surgery (NOTES(®); American Society for Gastrointestinal Endoscopy [Oak Brook, IL] and Society of American Gastrointestinal and Endoscopic Surgeons [Los Angeles, CA]) is a new approach that allows surgical manipulations and specimen extractions through the natural orifices such as the vagina. There have been limited numbers of cases about the adaptation of NOTES for ventral hernia repairs. Here, we aimed to present two more cases and highlight our technical differences compared with the previously reported instances. Patients and Methods: Two patients (43 and 46 years old; body mass index of 29 and 30?kg/m(2), respectively) were treated with hybrid transvaginal incisional hernia repairs. Two 5-mm abdominal trocars were used to monitor transvaginal access, adhesiolysis, dissection of the hernia, and tuckering of the mesh. A 15-mm transvaginal trocar was used for scope and mesh introduction into the abdomen. Defects were 3-5?cm in diameter. Results: A rigid 5-mm laparoscope was used. The composite synthetic meshes were, respectively, 11 and 13?cm in diameter. These were passed through the vagina without any protection such as a bag or sheath. No conversion or additional port was required. Respective operative times were 120 and 180 minutes, and the patients were discharged uneventfully on the second day. One patient had seroma, which was managed conservatively (aspiration of 20?mL on Day 7). There were no recurrences after 7 and 13 months, respectively. Conclusions: Conventional laparoscopic equipment can be used for hybrid transvaginal incisional hernia repair. An anti-adhesive synthetic mesh can be inserted through the vaginal trocar without protective devices. The main advantage of this technique is to avoid 10-15-mm abdominal trocars, which increase the risk of trocar-site hernias themselves. PMID:24844529

[Ultrasonography in serous coxitis].  

PubMed

Ultrasonography is a rapid, reliable and painless technique for diagnosis of transient synovitis and other conditions with effusion of the hip joint. We therefore recommend ultrasonography as the primary imaging method in all patients with acute and subacute pain in the hip and thigh. The diagnostic criterion for intracapsular effusion is a side difference greater than or equal to 2.0 mm in the distance between the anterior joint capsule and the femoral neck. Ultrasonography is also useful in following the resorption of the effusion during the active stage of transient synovitis and in assessing the hip joint for possible development of coxa magna and Legg-Calvé-Perthes disease at later follow-up. Radiography and scintimetry may be omitted in uncomplicated cases but should be employed when Legg-Calvé-Perthes disease is suspected. PMID:1948904

A pilot study on real-time transvaginal ultrasonographic elastography of cystic ovarian lesions  

PubMed Central

Background & objectives: This study was carried out to determine the appearance of various cystic ovarian lesions on transvaginal real-time ultrasonographic elastography and to investigate its potential in the differential diagnosis of cystic ovarian lesions. Methods: Twenty six women (age range, 27-71 yr; mean age 42 ± 16 yr) with cystic ovarian masses underwent transvaginal B-mode and Doppler ultrasonography, and transvaginal real-time ultrasonographic elastography. Those having ovarian cysts with solid components underwent to biopsy or surgical excision. The elasticity colour code (pattern 1-5), and strain index of cystic ovarian lesions were analyzed and associated with histopathological diagnosis. Results: Eleven of 26 ovarian cysts (42%) (diameter range, 3.2-4.5 cm) without solid component were not colour coded with blue or colour coded with blue-red-green heterogenous mosaic pattern. Fifteen of 26 cystic ovarian lesions (58%) (diameter range, 3.5-6.5 cm) had solid components. Among these, two had colour pattern 5, their strain indexes were 3.7 and 4, and their histopathologic diagnosis were germ cell carcinoma. One had colour pattern 5, with strain index 13.6, and histopathologic diagnosis was clear cell carcinoma. Interpretation & conclusions: Transvaginal real-time ultrasonographic elastography has potential role in the differential diagnosis of cystic ovarian lesions and this technique may be useful in differentiation of the benign lesions from those of malignant.

We present a case of a 3-year-old male with history of minor trauma, who was brought in by ambulance from the playground where he had an acute mental status change and was noted to be hypotensive on initial evaluation. History and examination did not indicate a clear etiology of his symptoms. Point-of-care emergency ultrasonography revealed free fluid in the abdomen and expedited the care of the child's unexpected intra-abdominal hemorrhage from an occult abdominal tumor. This case demonstrates the ability of practitioners to expedite and focus care with the use of rapid assessment with ultrasonography in the pediatric emergency department. PMID:23034502

Transvaginal Sonographic Evaluation of the Cervix in Asymptomatic Singleton Pregnancy and Management Options in Short Cervix  

PubMed Central

Preterm delivery (PTD), defined as birth before 37 completed weeks of gestation, is the leading cause of perinatal morbidity and mortality. Evaluation of the cervical morphology and biometry with transvaginal ultrasonography at 16–24 weeks of gestation is a useful tool to predict the risk of preterm birth in low- and high-risk singleton pregnancies. For instance, a sonographic cervical length (CL) > 30?mm and present cervical gland area have a 96-97% negative predictive value for preterm delivery at <37 weeks. Available evidence supports the use of progesterone to women with cervical length ?25?mm, irrespective of other risk factors. In women with prior spontaneous PTD with asymptomatic cervical shortening (CL ? 25?mm), prophylactic cerclage procedure must be performed and weekly to every two weeks follow-up is essential. This article reviews the evidence in support of the clinical introduction of transvaginal sonography for both the prediction and management of spontaneous preterm labour.

Background Non traumatic gastrointestinal emergencies in the children and neonatal patient is a dilemma for the radiologist in the emergencies room and they presenting characteristics ultrasound features on the longitudinal and axial axis. The most frequent emergencies are : appendicitis, intussusceptions, hypertrophic pyloric stenosis, volvulus due to intestinal malrotation. The aim of this article is to familiarize the reader with the US features. Methods A retrospective analysis of 200 ultrasound examinations performed in neonatal and children patients with fever, abdominal pain, leukocytosis, vomiting and diarrhea were evaluated. Results Of 200 exame 50 cases of intussusceptions, 100 cases of appendicitis, 20 cases associated with abscess;10 gangrenous appendicitis with absence a color Doppler , and 10 cases of perforated appendicitis at tomography computer integration and 10 cases of volvulus was found. Conclusions Ultrasonography (US) is therefore rapidly becoming an important imaging modality for the evaluation of acute abdominal pain, particularly in pediatric patients, where satisfactory examination is often not achievable for the attending clinicians. US provides excellent anatomic detail on the longitudinally and axial axis .

Assessment of inflammatory activity in rheumatoid arthritis: a comparative study of clinical evaluation with grey scale and power Doppler ultrasonography  

PubMed Central

Objective: To compare the clinical assessment of overall inflammatory activity in patients with rheumatoid arthritis (RA) with grey scale and power Doppler (PD) ultrasonography (US). Methods: Ninety four consecutive patients with RA were included. Demographic and clinical data, C reactive protein (CRP) level, and erythrocyte sedimentation rate (ESR) were recorded for each patient. The presence of tenderness, swelling, and a subjective swelling score from 1 to 3 were independently assessed by two rheumatologists, who reached a consensus in 60 joints examined in each patient. All patients underwent a US examination by a third blinded rheumatologist, using PD. US joint effusion, synovitis, and PD signal were graded from 1 to 3 in the 60 joints. Joint count and joint index for effusion, synovitis, and PD signal were recorded. A 28 joint count for clinical and US variables was calculated. Interobserver reliability of the US examination was evaluated by a fourth blinded rheumatologist. Results: US showed significantly more joints with effusion (mean 15.2) and synovitis (mean 14.6) than clinical examination (mean 11.5, p<0.05). A significant correlation was found between joint count and joint index for swelling, US effusion, synovitis, and PD signal. The 28 joint count for effusion, synovitis, and PD signal correlated highly with the corresponding 60 joint counts. US findings correlated better with CRP and ESR than clinical measures. Interobserver reliability was better for US findings than for clinical assessment. Conclusion: US is a sensitive method for assessing joint inflammatory activity in RA, complementary to clinical evaluation.

Feasibility of Using Intravascular Ultrasonography for Assessment of Giant Cavernous Aneurysm after Endovascular Treatment: A Technical Report  

PubMed Central

Introduction Intravascular ultrasonography (IVUS) has been shown as a valuable adjunct imaging tool during endovascular procedures but its value in detection of any recurrence during follow up after endovascular coil embolization of large and giant intracranial aneurysms is not reported. Methods A 41 years old man who had been treated using stent assisted coil embolization for cavernous segment aneurysm of the left internal carotid artery underwent 60 month angiographic follow up. Concurrently, IVUS catheter was advanced under fluoroscopic guidance inside the cavernous portion of the left internal carotid artery. Then IVUS images were used to visualize the stent, coil loops, and aneurysm neck. Results The angiographic images were limited because of superimposition of the aneurysm on the parent vessel in all projections. IVUS images demonstrated that the stent was patent along its whole length and there was no sign of stent deformity or in-stent thrombosis. Loops of the coil were visualized as hyperechoic signals inside the aneurysm and there was no sign of herniated loops of coil inside the stent. Conclusion In this case report, we observed that adjunct use of IVUS can provide valuable information not ascertained by angiography during follow up assessment of coil embolized aneurysm.

Prognostic assessment and treatment of primary gastric lymphomas: how endoscopic ultrasonography can help in tailoring patient management.  

PubMed

Endoscopic ultrasonography (EUS) has recently gained a pivotal role in the management of gastric lymphomas, especially in the diagnostic workup. Its accuracy and reliability have overcome those of other imaging techniques, such that it represents an invaluable tool for the management of gastric lymphomas. Although this technique is operator dependent, its application in large series has proved its reliability. Thus, it has generally been considered a useful tool for providing information crucial in deciding the treatment program, especially for mucosa-associated lymphoid tissue (MALT) lymphomas, for which EUS can provide an accurate evaluation of disease extension and treatment response probability. Limited-stage disease, confined to the submucosa, has a greater probability to respond to sole Helicobacter pylori eradication. In contrast, the value of EUS in response assessment and follow-up monitoring is still debated, with discordant opinions about its reliability and clinical advantages, because normalization of the EUS findings occurs with a considerable delay compared to the histologic evaluation. In the follow-up setting, preliminary data have indicated that persistently positive EUS findings in low-grade gastric lymphoma could represent a warning for a possible relapse. However, in high-grade gastric lymphoma, such findings do not have any clinical implications. PMID:24369919

Background The aim of the study was to compare the diagnostic accuracy of point-of-care cardiac ultrasonography performed by a novice examiner against results from a specialist in cardiology with expert skills in echocardiography, with regard to the assessment of six clinically relevant cardiac conditions in a population of ward patients from the Department of Cardiology or the Department of Cardiothoracic Surgery. Methods Cardiac ultrasonography was performed by a novice examiner at the bedside and images were interpreted in a point-of-care context with dichotomous outcomes (yes/no). Six outcome categories were defined: 1) pericardial effusion (?10 mm), 2) left ventricular dilatation (?62 mm), 3) right ventricular dilatation (?42 mm or???left ventricular diameter), 4) left ventricular hypertrophy (?13 mm), 5) left ventricular failure (EF???40%), 6) aortic stenosis (maximum flow velocity ?3 m/s). The examiner was blinded to the patients’ medical history and results from previous echocardiographic examinations. Results from the interpreted point-of-care ultrasonography examination were compared with echocardiographic diagnosis made by a specialist in cardiology. Results A total of 102 medical and surgical patients were included. Assessments were made in six categories totalling 612 assessments. There was agreement between the novice examiner and the specialist in 95.6% of the cases; overall sensitivity was 0.91 and specificity was 0.97. Positive predictive value was 0.92 and negative predictive value was 0.97. Kappa statistics showed good agreement between observers (?=0.88). Conclusions This study showed that a novice examiner was able to detect common and significant heart pathology in six different categories with good accuracy using POC ultrasonography.

Transvaginal low anterior resection for rectal cancer.  

PubMed

Adenocarcinoma of the lower rectum can be resected with a sphincter-sparing procedure but exposure of the lower pelvis may be difficult and sphincter function may be compromised. We have performed a low anterior resection for rectal cancer in a 69-year-old woman with mobilisation of the tumour and anastomosis performed transvaginally without a covering stoma. This way we could get good exposure of the lower rectum and anal sphincters. The patient made an uneventful recovery and was fully continent after surgery. Transvaginal low anterior resection is an alternative route which may be useful in cases of difficult exposure of low rectal cancer. PMID:18512019

Assessment of human baroreflex function using carotid ultrasonography: what have we learnt?  

PubMed

The arterial baroreflex is critical to both short- and long-term regulation of blood pressure. However, human baroreflex research has been largely limited to the association between blood pressure and cardiac period (or heart rate) or indices of vascular sympathetic function. Over the past decade, emerging techniques based on carotid ultrasound imaging have allowed new means of understanding and measuring the baroreflex. In this review, we describe the assessment of the mechanical and neural components of the baroreflex through the use of carotid ultrasound imaging. The mechanical component refers to the change in carotid artery diameter in response to changes in arterial pressure, and the neural component refers to the change in R-R interval (cardiac baroreflex) or muscle sympathetic nerve activity (sympathetic baroreflex) in response to this barosensory vessel stretch. The key analytical concepts and techniques are discussed, with a focus on the assessment of baroreflex sensitivity via the modified Oxford method. We illustrate how the application of carotid ultrasound imaging has contributed to a greater understanding of baroreflex physiology in humans, covering topics such as ageing and diurnal variation, and physiological challenges including exercise, postural changes and mental stress.

Assessment of renal volume by three-dimensional ultrasonography in pregnant bitches: an experimental study using virtual organ computer-aided analysis  

PubMed Central

Background To assess and to compare the renal volume evolution in bitches during pregnancy by two-dimensional (2D) ultrasonography using the ellipsoid technique (volume?=?length x width x depth x 0.523) and three-dimensional (3D) ultrasonography using the Virtual Organ Computer-aided AnaLysis (VOCAL) method. A longitudinal prospective study was performed with 17 normal Golden Retrievers bitches during pregnancy from heat to the last third of gestation. The ultrasound scans were performed by two veterinarians. The left and right kidneys were assessed in three moments (day 0?=?non-pregnant bitches; days 1st to 20th of pregnancy and days 21st to 40th of pregnancy) by three techniques (ellipsoid; VOCAL 12° and VOCAL 30°). For reproducibility calculations, we used the intraclass correlation coefficient (ICC). Results The inferential result of the volumes in ANOVA revealed the interaction effect between side and moment (p?=?0.009). The 3D techniques showed, in average, the same renal volumes (p?=?0.137) regardless of the side and moment. Considering the right side, the renal volume in the day 0 was smaller than the day 21st to 40th (p?=?0.029). Considering the left side, the renal volume at day 0 was smaller than the day 1st to 20th (p?=?0.020) and day 21st to 40th (p?=?0.007). It was found good intra observer reproducibility (ICC?>?0.9) and none of the three techniques showed a good inter observer reproducibility (ICC?ultrasonography using the VOCAL method (12° and 30°) had good correlation with the volume obtained by 2D ultrasonography method.

Comparison of ultrasonography with Doppler and MRI for assessment of disease activity in juvenile idiopathic arthritis: a pilot study  

PubMed Central

Background In juvenile idiopathic arthritis (JIA), the trend towards early therapeutic intervention and the development of new highly effective treatments have increased the need for sensitive and specific imaging. Numerous studies have demonstrated the important role of MRI and US in adult rheumatology. However, investigations of imaging in JIA are rare, and no previous study has been comparing MRI with Doppler ultrasonography (US) for assessment of arthritis. The aim of the present study was to compare the two imaging methods regarding their usefulness for evaluating disease activity in JIA, and to compare the results with those obtained in healthy controls. Methods In 10 JIA patients (median age 14 years, range 11–18), 11 joints (six wrists, three knees, two ankles) with arthritis were assessed by color Doppler US and MRI. The same imaging modalities were used to evaluate eight joints (three wrists, three knees, two ankles) in six healthy age- and sex-matched controls. The US examinations of both the patients and controls were compared with the MRI findings. Results In 10 JIA patients, US detected synovial hypertrophy in 22 areas of 11 joints, 86% of which had synovial hyperemia, and MRI revealed synovitis in 36 areas of the same 11 joints. Erosions were identified by US in two areas of two joints and by MRI in six areas of four joints. Effusion was shown by US in nine areas of six joints and by MRI in 17 areas of five joints. MRI detected juxta-articular bone marrow edema in 16 areas of eight joints. Conclusions The results of this pilot study indicate that both MRI and US provide valuable imaging information on disease activity in JIA. Importantly, the two techniques seem to complement each other and give partly different information. Although MRI is considered to be the reference standard for advanced imaging in adult rheumatology, US seems to provide useful imaging information that could make it an option in daily clinical practice, in JIA as well as in adult rheumatology. However, the current work represents a pilot study, and thus our results need to be confirmed in a larger prospective clinical investigation.

[Coronary artery dissection after blunt chest trauma: subacute and chronic phase assessment by intravascular ultrasonography: a case report].  

PubMed

A 35-year-old man sustained a steering wheel injury in a motor vehicle accident. Initial electrocardiography showed ST-segment elevation. Coronary angiography revealed a dissection of the right coronary artery and perfusion delay in the left anterior descending artery. Coronary stents were inserted into the left anterior descending artery. One month later, coronary angiography and intravascular ultrasonography showed that the dissection of the right coronary artery was still present. Coronary stents were inserted from the aorto-ostial lesion to the mid portion of the right coronary artery. Six months later, coronary angiography and intravascular ultrasonography revealed diffuse neointimal hyperplasia inside all of the stents, and the aorto-ostial stent had severe stenosis with perfusion delay. Severe neointimal hyperplasia was found inside the stents used for repair of the coronary artery dissection. PMID:15188611

To our knowledge, peritoneovaginal fistula is a complication of cystectomy that has not been reported before. We describe 2 patients in whom a transvaginal approach using a Martius flap was utilized to repair persistent vaginal leakage after cystectomy. At a mean follow-up of 20 months, both patients are free from vaginal leakage and have no evidence of recurrent fistula. This approach offers a safe and effective way to repair a peritoneovaginal fistula in a cystectomy patient. PMID:10925104

Open-access transvaginal sonography in women of reproductive age with abnormal vaginal bleeding: a descriptive study in general practice  

PubMed Central

Background Diagnostic ultrasonography is used by GPs in approximately 10% of patients of reproductive age with abnormal vaginal bleeding. Transvaginal sonography is recommended as a first-line diagnostic instrument for assessing uterine pathology. Aim To assess if findings resulting from openaccess sonography were in agreement with the GPs’ working hypotheses and if these findings contributed to GPs’ management. Design and setting Prospective observational cohort study of GPs working in the health district of the Academic Medical Center, Amsterdam and their patients consulting with abnormal vaginal bleeding. Method Data on patients’ history, GPs’ primary working hypotheses, and intended management were recorded. After sonography, GPs recorded their actual management. Results A total of 122 patients were included by 18 GPs from June 2003 to December 2004. Data from 89 patients were available for analysis. The GPs’ working hypotheses implied ‘no structural pathology’ in 65/89 patients, and ‘fibroids’ in 24/89 patients. Sonographic findings were confirmed in 50/65 patients where ‘no structural pathology’, and in 14/24 of those where ‘fibroids’ were expected. Initially, GPs had intended to refer nine patients to a gynaecologist. Actual management after sonographic assessment was watchful waiting or drug therapy in 57/89 patients. Eighty-nine per cent of these patients had normal sonographic findings. The actual referral rate rose to 27/89 patients. In 17 referred patients, sonographic findings were suggestive of intracavitary abnormalities. Conclusion Open-access sonography contributed to more accurate diagnoses and improved GPs’ management of women with abnormal vaginal bleeding.

Artifacts in musculoskeletal ultrasonography.  

PubMed

During the past 2 decades, high-resolution ultrasonography (US) has been increasingly utilized in the diagnosis of musculoskeletal trauma and diseases with results comparable with MR imaging. US has an advantage over other cross-sectional modalities in many circumstances due to its superior spatial resolution and ability to allow dynamic assessment. When performing musculoskeletal US, the examiner has to be knowledgeable in the complex anatomy of the musculoskeletal system and US imaging technique. Additionally, he or she must be familiar with several common imaging artifacts in musculoskeletal US that may be mistaken for pathology, as well as several artifacts that frequently accompany pathologic conditions. These artifacts may occur with both B-mode gray-scale and Doppler imaging. In this article, we discuss common artifacts seen in musculoskeletal US and techniques to avoid or minimize these artifacts during clinical US examinations. PMID:24515877

Transvaginal colour Doppler ultrasound in normal and abnormal early pregnancy.  

PubMed

The value of transvaginal colour and pulse wave Doppler in the diagnosis of pathologic early intrauterine and tubal pregnancy was assessed. Forty-one normal pregnancies, 6 blighted ovum, 6 missed abortions, and 22 suspected ectopic pregnancies (13 proven tubal pregnancies) were examined. Single 5 MHz transvaginal colour and pulse wave Doppler probe was used and once clear signals from uterine vessels, umbilical artery or trophoblastic vessels were obtained. Resistance Index (peak systole--end diastole/peak systole, RI) from the corresponding waveforms was calculated. In 41 normal pregnancies (examined before termination of pregnancy) with gestational age ranged from 6 to 10 weeks mean RI in uterine artery was 0.81 (SD 0.06), in the umbilical artery 1 (SD 0), and 0.48 (0.08) in the trophoblastic vessels. Mean RI from uterine arteries in six pregnancies with blighted ovum and six with missed abortion were 0.77 (SD 0.11) and 0.69 (SD 0.13) respectively. In 2 out of 6 cases of blighted ovum and 4 out of 6 cases of missed abortion flow in trophoblastic vessels could not be detected. These findings suggest ineffective early placentation in pathologic pregnancy. Twenty-two patients with suspected ectopic pregnancy (raised serum beta HCG with empty uterus, amenorrhoea with abdominal pain and/or palpable abdominal mass) were examined. In 13 cases tubal pregnancy was confirmed by laparoscopy and/or laparotomy. In the remaining nine cases the diagnosis was excluded by means of laparoscopy or subsequent negative beta HCG. Doppler diagnosis of ectopic pregnancy was made when colour flow in adnexa with RI less than 0.56 was revealed.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:2200863

Of these, 3359 participants with stool egg positive underwent ultrasonography of the upper abdomen. The hepatobiliary abnormalities detected by ultrasound are described here. This study found a significantly higher frequency of advanced periductal fibrosis in persons with chronic opisthorchiasis (23.6%), particularly in males. Risks of the fibrosis included intensity of infection, and age younger than 30 years. Height of left lobe of the liver, cross-section of the gallbladder dimensions post fatty meal, sludge, and, interestingly, intrahepatic duct stones were significantly associated with the advanced periductal fibrosis. Eleven suspected cholangiocarcinoma (CCA) cases were observed. This study emphasizes the current status of high O. viverrini infection rate and the existence of hepatobiliary abnormalities including suspected CCA in opisthorchiasis endemic areas of Thailand.

Suitability of epididymal and testicular ultrasonography and computerized image analysis for assessment of current and future semen quality in the ram.  

PubMed

Breeding soundness evaluation (BSE) is the primary assessment for determining the reproductive potential of male animals. This method, however, cannot be used to evaluate semen frequently or to predict future semen quality. Computerized analysis of ultrasonographic images provides information on histophysiological changes in male reproductive organs. We hypothesized that: (i) semen parameters would correlate with ultrasonographic characteristics of the distal region (cauda) of the epididymis and (ii) testicular ultrasound images and/or circulating testosterone concentration would predict future semen quality in the ram. Six adult rams underwent BSE and scrotal ultrasonography approximately 60 d apart (average duration of the spermatogenic cycle) both during the breeding (December and February) and non-breeding (June and August) seasons. An inverse correlation was found between pixel intensity (numerical pixel values) of the epididymes and percentage of sperm in semen with normal morphology (r = -0.46, P < 0.05). Pixel heterogeneity (standard deviation of pixel values) correlated negatively with percentage of sperm with normal morphology (r = -0.42, P < 0.05) and directly with percentage of spermatozoa with abnormal tails (r = 0.43, P < 0.05). Pixel heterogeneity of testicular parenchyma obtained approximately 60 d prior to semen evaluation inversely correlated with percentage of sperm with normal morphology (r = -0.73, P < 0.01) and sperm progressive motility (r = -0.76, P < 0.01), and directly with percentage of sperm with abnormal tails (r = 0.72, P < 0.01) and loose heads (r = 0.79, P < 0.01). We concluded that scrotal ultrasonography combined with computer-assisted analyses of epididymal and testicular echotexture in the ram was a valuable method for determining certain current and future semen parameters, respectively.

Assessment of Carotid Atherosclerosis in Type 2 Diabetes Mellitus Patients with Microalbuminuria by High-Frequency Ultrasonography  

PubMed Central

The aim of this study is to evaluate carotid atherosclerosis in patients of type 2 diabetes mellitus with microalbuminuria (MA) by high-frequency ultrasonography. Two hundred and fifty patients of type 2 diabetes mellitus were divided into two groups according to urinary albumin excretion rate (UAER): normoalbuminuria group (130 cases) and microalbuminuria group (120 cases). The intimal-medial thickness (IMT) and the atherosclerotic plaques of carotid artery were observed in both groups by high-frequency ultrasound. Fasting blood glucose (FBG), hemoglobin A1c, and lipid profiles were measured. The values of IMT of microalbuminuria group were significantly higher than those of normoalbuminuria group (P < 0.05). In univariate analysis, IMT was positively and significantly associated with age (r = 0.265, P < 0.05), waist circumference (r = 0.263, P < 0.05), body mass index (r = 0.285, P < 0.05), systolic blood pressure (r = 0.276, P < 0.05), UAER (r = 0.359, P < 0.05), HbA1c (r = 0.462, P < 0.05) and, duration of diabetes (r = 0.370, P < 0.05). In multivariate linear regression analysis, UAER and HbA1c were independent predictors of IMT (P < 0.05 for all). In the two groups, the rate of soft plaques was higher than that of dense plaques and calcified plaques. In conclusion, there is a significant association between microalbuminuria and IMT which is regarded as the early sign of carotid atherosclerosis in type 2 diabetic patients.

Review of ultrasonography of malignant neck nodes: greyscale, Doppler, contrast enhancement and elastography  

PubMed Central

Abstract Assessment of neck lymph nodes is essential in patients with head and neck cancers for predicting the patient’s prognosis and selecting the appropriate treatment. Ultrasonography is a useful imaging tool in the assessment of neck lymph nodes. Greyscale ultrasonography assesses the size, distribution, and internal architecture of lymph nodes. Doppler ultrasonography evaluates the intranodal vascular pattern and resistance of lymph nodes. Contrast-enhanced ultrasonography provides information on lymph node parenchymal perfusion. Elastography allows qualitative and quantitative assessment of lymph node stiffness. This article reviews the value of greyscale, Doppler and contrast-enhanced ultrasonography as well as elastography in the assessment of malignant nodes in the neck.

Correlation and agreement between contrast-enhanced ultrasonography and perfusion computed tomography for assessment of liver metastases from endocrine tumors: normalization enhances correlation.  

PubMed

We studied correlation and agreement between perfusion parameters derived from contrast-enhanced ultrasonography (CEUS) and computed tomography (CT). Both techniques were performed in 16 patients with proven liver metastases from endocrine tumor. Replenishment study after ultrasound-induced destruction of microbubbles was used for CEUS quantification. CEUS-derived relative values of blood flow, blood volume and mean transit time were compared with perfusion CT-derived parameters measured in the same tumors. Significant correlation was observed between CEUS normalized values and CT absolute tumor values for blood flow (r = 0.58; p = 0.018), blood volume (r = 0.61; p = 0.012) and mean transit time (r = 0.52; p = 0.037). Correlation was not significant for non-normalized values. Agreement between CEUS normalized values and perfusion CT relative values was significant (p < 0.04). Estimated bias between CEUS and CT for relative perfusion values was -1.38 (-5.02; 2.27) for blood flow, +0.26 (-0.79; 1.31) for blood volume and +0.21 (-0.46; 0.87) for mean transit time. We conclude that normalization markedly increased correlation between CEUS- and CT-derived perfusion values and allowed agreement assessment. PMID:22475696

Occurrence and characteristics of residual follicles formed after transvaginal ultrasound-guided follicle aspiration in cattle.  

PubMed

Ultrasound-guided transvaginal follicle aspiration is used to recover cumulus-oocyte complexes (for IVF) and to synchronize follicular wave emergence (ablation of dominant follicle). Although aspirated follicles are generally supposed to undergo immediate atresia, there are indications that they may remain active. The objective was to evaluate the occurrence and characteristics of residual follicles (RF) after transvaginal follicle aspiration in cattle. Ovarian follicular wave emergence was synchronized in Holstein cows (N = 13) in the presence (groups 1 and 3) or absence (groups 2 and 4) of norgestomet implants. The largest follicle was aspirated at a diameter of 8 mm (groups 1 and 2) or 12 mm (groups 3 and 4). Ovarian follicles were visualized (transrectal ultrasonography) every 12 h after wave emergence. Follicular fluid samples were collected from the largest follicle and from the ensuing RF and concentrations of estradiol and progesterone were determined. After aspiration, 73.2% (52/71) of the follicles refilled with fluid, and a new antrum was detected 12 to 24 h later. Norgestomet did not affect (P > 0.05) RF occurrence or diameter, but in RF from group 4, concentrations of estradiol decreased (-530.7 ± 133.9 ng/mL; P < 0.01) whereas progesterone increased (+429.6 ± 171.7 ng/mL; P < 0.05) relative to preaspiration. In RF, there were three steroidogenesis patterns: (1) high estradiol concentration and high estradiol:progesterone ratio (estradiol-active RF); (2) low estradiol, but high progesterone concentrations (luteinized RF); and (3) low estradiol and low progesterone concentrations (inactive RF). Estradiol-active RF were more likely (P < 0.05) from follicles with high estradiol concentrations (regardless of diameter). In conclusion, fluid-filled structures (RF) with variable steroid production patterns are frequently formed after ultrasound-guided follicle aspiration. The occurrence and features of these RF depended on the diameter and status of these follicles before aspiration. PMID:23174772

Thorax, Trachea, and Lung Ultrasonography in Emergency and Critical Care Medicine: Assessment of an Objective Structured Training Concept  

PubMed Central

Background and Study objective. Focused lung ultrasound (LUS) examinations are important tools in critical care medicine. There is evidence that LUS can be used for the detection of acute thoracic lesions. However, no validated training method is available. The goal of this study was to develop and assess an objective structured clinical examination (OSCE) curriculum for focused thorax, trachea, and lung ultrasound in emergency and critical care medicine (THOLUUSE). Methods. 39 trainees underwent a one-day training course in a prospective educational study, including lectures in sonoanatomy and -pathology of the thorax, case presentations, and hands-on training. Trainees' pre- and posttest performances were assessed by multiple choice questionnaires, visual perception tests by interpretation video clips, practical performance of LUS, and identification of specific ultrasound findings. Results. Trainees postcourse scores of correct MCQ answers increased from 56 ± 4% to 82 ± 2% (mean± SD; P < 0.001); visual perception skills increased from 54 ± 5% to 78 ± 3% (P < 0.001); practical ultrasound skills improved, and correct LUS was performed in 94%. Subgroup analysis revealed that learning success was independent from the trainees' previous ultrasound experience. Conclusions. THOLUUSE significantly improves theoretical and practical skills for the diagnosis of acute thoracic lesions. We propose to implement THOLUUSE in emergency medicine training.

Delayed presentation of complete ureteral obstruction deligated transvaginally.  

PubMed

Complete ureteral obstruction with delayed presentation is managed first by percutaneous nephrostomy and later with ureteral deligation, reimplantation, and stenting. Transvaginal deligation of complete obstruction after delayed presentation has not been described. We present two cases of ureteral ligation after pelvic reconstructive surgery. The first patient underwent high uterosacral ligament vaginal vault suspension then presented on postoperative day 22. The second patient underwent anterior colporrhaphy and presented on postoperative day 6. Both patients had flank pain, elevated creatinine, and signs of complete obstruction on CT scan. They both underwent transvaginal ureterolysis, retrograde stent placement, and later removal without any sequelae. Transvaginal ureterolysis of complete obstruction after delayed presentation is better tolerated and less morbid than traditional management. PMID:20976442

Transvaginal laparo-endoscopic single-site sigmoidectomy.  

PubMed

We report a case of sigmoid colon resection by single-incision laparoscopic surgery using transvaginal access. The patient was a 54-year-old woman with early stage sigmoid cancer who had no previous surgery and had a body mass index of 23.5 kg/m(2). The operative time was 270 min, and the blood loss was negligible. We used only transvaginal access, since no transabdominal assistance was required. No complications occurred. Minimal postoperative pain and a rapid recovery of gastrointestinal function were observed. As novel equipment is introduced into clinical practice, transvaginal laparoscopic procedures will most likely become increasingly popular in abdominal surgery. In particular, this type of procedure will have a more defined role in colorectal surgery. Indeed, in the future, it may become an alternative for natural orifice transluminal endoscopic surgery.

An assessment of the muscle blood perfusion of extremities that underwent crush injury by using contrast-enhanced ultrasonography: An animal experiment.  

PubMed

BACKGROUND: This research aimed to study the assessment of local muscle microcirculation perfusion of extremities that underwent crush injuries by using contrast-enhanced ultrasonography (CEUS). METHODS: A total of 28 New Zealand rabbits were anesthetized by using intramuscular pentobarbital sodium (30 mg/kg). A balloon cuff device was used to create crush injuries to the left hind leg of each rabbit with a force of 18.6 kPa. CEUS was performed at the 0.5th, 2nd, 6th, 24th, and 72nd hour after the release of the crush pressure. Peak intensity (PI) of the crushed regions was compared with those of the uncrushed regions and before the creation of crush injury. Receiver operating characteristic analysis was used to determine the diagnostic value of PI for the crushed region. RESULTS: During the 72nd hour after the release of the crush pressure, 5 of the 28 rabbits died, and thus, their statistics were eliminated from the experiment. At different time points after the release of the crush pressure, the crushed regions in all 23 survivals showed quick and high enhancement, and their intensities were higher than those of the uncrushed region in the arterial phase. The time-intensity curves of the crushed regions all appeared as rapid lift-gradual drop. PIs were obviously higher in the crushed regions than in the uncrushed regions and than those before the creation of crush injury (p < 0.001). Receiver operating characteristic curves showed that extremity crush injury was diagnosed by using PI value. CONCLUSION: CEUS presents that the microcirculation perfusion of the crushed muscle increased obviously after the release of the crush pressure. PIs evaluated quantitatively the microcirculation perfusion changes. It may suggest a potential alternative for evaluating microcirculation abnormality of the muscle crush injury to the extremities.

Bench-to-bedside review: contrast enhanced ultrasonography--a promising technique to assess renal perfusion in the ICU.  

PubMed

Acute kidney injury (AKI) is common in critically ill patients and associated with important morbidity and mortality. Although alterations in renal perfusion are thought to play a causative role in the pathogenesis of AKI, there is, to date, no reliable technique that allows the assessment of renal perfusion that is applicable in the ICU. Contrast-enhanced ultrasound (CEUS) is an ultrasound imaging technique that makes use of microbubble-based contrast agents. These microbubbles, when injected into the bloodstream, allow visualization of vascular structures and, with contrast-specific imaging modes, detection of blood flow at the capillary level. Some recent CEUS-derived approaches allow quantification of blood flow in several organs, including the kidney. Current generation ultrasound contrast agents have strong stability and safety profiles. Along with post-marketing surveillance, numerous studies report safe administration of these agents, including in critically ill patients. This review presents information on the physical principles underlying CEUS, the methods allowing blood flow quantification and the potential applications of CEUS in critical care nephrology, currently as a research tool but perhaps in the future as a way of monitoring renal perfusion.

Ultrasonography of the lumbar spine: sonoanatomy and practical applications.  

PubMed

Ultrasonography of the bones and joints has gained considerable ground in the field of rheumatology over the past decade and is now used in everyday practice both for diagnostic purposes and to guide local injections. However, the use of ultrasonography is virtually confined to the peripheral joints, whereas spinal diseases make a major contribution to rheumatology practice. Studies have established that ultrasonography of the lumbar spine is feasible. Adequate equipment and familiarity with spinal sonoanatomy are required. In this update, we suggest starting with a systematic examination of the lumbar spine to assess the various anatomic structures, from the thoracolumbar fascia superficially to the posterior part of the vertebras at the deepest level. The ligaments, erector spinae muscles, facet joints, and transverse processes can be visualized. Ultrasonography can serve to guide injections into the facet joints, about the nerve roots, and into the iliolumbar ligaments; as well as to identify relevant landmarks before epidural injection. Although diagnostic applications are more limited at present, systematic studies of abnormal ultrasonography findings will allow evaluations of the potential usefulness of ultrasonography for diagnosing spinal disorders. The depth of the spinal structures limits the ability to obtain high-resolution images. However, future technical improvements in ultrasound transducers and machines, together with the growing number of physicians trained in ultrasonography, can be expected to benefit the development of spinal ultrasonography in the near future.

Assessment of intrahepatic blood flow by Doppler ultrasonography: Relationship between the hepatic vein, portal vein, hepatic artery and portal pressure measured intraoperatively in patients with portal hypertension  

PubMed Central

Background Abnormality of hepatic vein (HV) waveforms evaluated by Doppler ultrasonography has been widely studied in patients with chronic liver disease. We investigated the correlation between changes in HV waveforms and portal vein velocity (PVVel), the hepatic artery pulsatility index (HAPI), and also the extent of abnormal Doppler HV waveforms expressed as damping index (DI), severity of portal hypertension expressed as Child-Pugh scores and portal pressure (PP) measured directly from patients with portal hypertension (PHT) to evaluate the indicative value of abnormal HV waveforms and discuss the cause of abnormal HV waveform. Methods Sixty patients who had been diagnosed with PHT and accepted surgical therapy of portosystemic shunts were investigated. PP was measured intraoperatively. Thirty healthy volunteers with no history of chronic liver disease were enrolled as the control group. HV waveforms were categorized as triphasic, biphasic or monophasic. DI was compared as the quantitative indicator of abnormal HV waveforms. Another two Doppler parameters, PVVel and HAPI were also measured. These Doppler features were compared with PP, Child-Pugh scores and histological changes assessed by liver biopsy. Results In the patient group, the Doppler flow waveforms in the middle HV were triphasic in 31.6%, biphasic in 46.7%, and monophasic in 21.6% of subjects. These figures were 86.7%, 10.0%, and 3.3%, respectively, in healthy subjects. With the flattening of HV waveforms, the HAPI increased significantly (r = 00.438, p < 0.0001), whereas PVVel decreased significantly (r = -0.44, p <0.0001). Blood flow parameters, HAPI, PVVel and HV-waveform changes showed no significant correlations with Child-Pugh scores. The latter showed a significant correlation with PP (r = 0.589, p = 0.044). Changes of HV waveform and DI significantly correlated with PP (r = 0.579, r = 0.473, p <0.0001), and significant correlation between DI and Child-Pugh scores was observed (r = 0.411, p = 0.001). PP was significantly different with respect to nodule size (p < 0.05), but HV-waveform changes were not significantly correlated with pathological changes. Conclusion In patients with PHT, a monophasic HV waveform indicates higher portal pressure. Furthermore, quantitative indicator DI can reflect both higher portal pressure and more severe liver dysfunction. Flattening of HV waveforms accompanied by an increase in the HAPI and decrease in PVVel support the hypothesis that histological changes reducing HV compliance be the cause of abnormality of Doppler HV waveforms from the hemodynamic angle.

[Significance of transvaginal ultrasonic examination in the first pregnancy trimester].  

PubMed

The authors report their results obtained by performing transvaginal sonography in 180 patients in the first trimester of pregnancy. It has been found that both normal and pathological cases could be diagnosed 1 week earlier than had been possible with transabdominal method. Minimum size of the intrauterin gestational sac was found to be 3 mm. Cardiac activity could be evaluated in embrios with a size of 7 mm or greater in all cases. According to them the diagnosis of blighted ovum and missed abortion seems to be confirmed when an "empty sac" is larger than 20 mm, or the absence of heart motion is detected in an embrio greater than 10 mm, without repeated scan. High sensitivity was found in ectopic pregnancies especially in unruptured cases. The possibility of qualitative analysis of "free fluid" in Douglas pouch and diagnosis of congenital anomalies in very early pregnancy are promising. Transvaginal sonography is recommended in all cases when transabdominal technique is equivocal. PMID:2263358

Abstract In our study, we evaluate the diagnostic and therapeutic efficacy of transvaginal ultrasound-guided aspiration of benign ovarian cysts in selected patients. A total of 46 women with benign ovarian cysts were referred to our outpatient clinic. The aspirated fluid was collected and sent for cytological analysis. All women were re-evaluated at 1, 3 and 6 months after the procedure. The cytological analysis was negative for malignancy in all cases. Our study showed an overall recurrence rate for ovarian cysts of 39.1%. Women with endometriotic ovarian cysts have an increased incidence of recurrence, 62.5% (n = 5), in comparison with serous cysts, 35.2% (n = 12) and serous-haemorrhagic cysts, 15% (n = 1), ?(2) = 9.913, df = 2, p = 0.007. The results of our study reveal that transvaginal ultrasound-guided aspiration of benign ovarian cysts is a simple, safe and effective procedure. PMID:24483623

Laparoscopic sacrocolpopexy versus transvaginal mesh for recurrent pelvic organ prolapse.  

PubMed

Both expert surgeons agree with the following: (1) Surgical mesh, whether placed laparoscopically or transvaginally, is indicated for pelvic floor reconstruction in cases involving recurrent advanced pelvic organ prolapse. (2) Procedural expertise and experience gained from performing a high volume of cases is fundamentally necessary. Knowledge of outcomes and complications from an individual surgeon's audit of cases is also needed when discussing the risks and benefits of procedures and alternatives. Yet controversy still exists on how best to teach new surgical techniques and optimal ways to efficiently track outcomes, including subjective and objective cure of prolapse as well as perioperative complications. A mesh registry will be useful in providing data needed for surgeons. Cost factors are also a consideration since laparoscopic and especially robotic surgical mesh procedures are generally more costly than transvaginal mesh kits when operative time, extra instrumentation and length of stay are included. Long-term outcomes, particularly for transvaginal mesh procedures, are lacking. In conclusion, all surgery poses risks; however, patients should be made aware of the pros and cons of various routes of surgery as well as the potential risks and benefits of using mesh. Surgeons should provide patients with honest information about their own experience implanting mesh and also their experience dealing with mesh-related complications. PMID:22930214

A modified posterior pelvic exenteration technique in a woman: (a simplified method with using transvaginal way).  

PubMed

We represent a simplified surgical method for posterior pelvic exenteration in a woman by using the transvaginal way in addition to classic abdominal approach. A modified posterior pelvic exenteration technique was performed in a patient with bulky pelvic tumor. The transvaginal way was used for the deep perineal dissection when the abdominal dissection was arrested. An ultralow coloanal anastomosis was completed by using the transvaginal way. After the recovery period, the patient was discharged from hospital without any complication. The transvaginal access should be reminded in the circumstances of the abdominal dissection arrested in posterior pelvic exenteration operations in women. PMID:24082597

General principles of carotid Doppler ultrasonography  

PubMed Central

Carotid Doppler ultrasonography is a popular tool for evaluating atherosclerosis of the carotid artery. Its two-dimensional gray scale can be used for measuring the intima-media thickness, which is very good biomarker for atherosclerosis and can aid in plaque characterization. The plaque morphology is related to the risk of stroke. The ulceration of plaque is also known as one of the strong predictors of future embolic event risk. Color Doppler ultrasonography and pulse Doppler ultrasonography have been used for detecting carotid artery stenosis. Doppler ultrasonography has unique physical properties. The operator should be familiar with the physics and other parameters of Doppler ultrasonography to perform optimal Doppler ultrasonography studies.

Transvaginal sonographic diagnosis of live monochorionic twin ectopic pregnancy.  

PubMed

Ectopic pregnancy is a leading cause of pregnancy-related deaths; its incidence has progressively increased in recent years. Spontaneous twin ectopic pregnancy, however, is extremely rare. Among more than 100 reported cases of twin tubal pregnancies, only 5 cases in which fetal cardiac motion has been visualized in both embryos have been reported. We describe an additional case of a live monochorionic twin ectopic pregnancy in a patient with no predisposing factor. With transabdominal sonography, we initially diagnosed a single ectopic pregnancy, visualized as an ill-defined mass in the left adnexa. However, with transvaginal sonography, we determined the left adnexal mass to contain a single monochorionic gestational sac with 2 embryos, each with cardiac motion. These findings were confirmed with color Doppler sonography and at laparotomy. The introduction of high-resolution transvaginal sonography has resulted in the earlier diagnosis of ectopic pregnancy and has contributed to a recent decrease in the maternal mortality and morbidity associated with this condition.

Transvaginal color Doppler in the assessment of abnormal early pregnancy.  

PubMed

The study groups comprised 61 pregnant women whose gestational age ranged from 7 to 12 weeks from the last menstrual period. All patients apparently had a normal developing pregnancy; there were no clinical symptoms of pathology e.g. bleeding in early pregnancy. Eighty-two patients with a clinically and ultrasonographically normal pregnancy whose gestational age ranged from 7 to 12 weeks, served as a control group. When the anatomical position of investigated area have been obtained clearly, pulsed wave Doppler sample volume was placed on the structures of interest: the both uterine arteries and intervillous space. There is no statistically significant difference between the Resistance Index (RI) in the left or right uterine artery (P greater than 0.01) and among investigated groups of patients (P greater than 0.01). The intervillous blood flow RI in the case of molar pregnancy was 0.38 with SD +/- 0.03; in blighted ovum 0.43 with SD +/- 0.03, and in missed abortion 0.43 with SD +/- 0.02. It should be stressed that in nine (31%) cases of blighted ova and in five (26%) cases of missed abortion, intervillous space flow could not be detected. In the control group, intervillous blood flow was always visualized and the mean RI was 0.45 with SD - 0.04. Statistical analysis showed significantly higher RI in control group in comparison with other groups of patients (P less than 0.01), and significantly lower RI in molar pregnancy in comparison with other groups of patients (P less than 0.01). There was no difference in RI between blighted ova and missed abortions (P greater than 0.01). PMID:1748936

A prospective, randomized, controlled trial assessing diazepam to reduce perception and recall of pain during transrectal ultrasonography-guided biopsy of the prostate.  

PubMed

Abstract Background and Purpose: The effect of oral anxiolytics in diminishing patient discomfort and pain perception has been demonstrated in GI endoscopy, percutaneous coronary interventions, and various procedures in the emergency department setting, but has not been prospectively studied in the setting of prostate biopsy. The purpose of this study was to investigate the effect of diazepam on pain perception during and after prostate biopsy. Patients and Methods: Sixty patients undergoing prostate biopsy at a single academic institution were enrolled into a prospective, randomized, placebo-controlled study. A questionnaire was administered prebiopsy to determine baseline discomfort and pain history. A visual analog pain scale was used to determine pain associated with each step of the transrectal Ultrasonography-guided prostate biopsy and was administered 20 minutes after biopsy and 1 week later. Responses were compared between groups using the Mann-Whitney U test, Fisher exact test, and Wilcoxon signed rank test as appropriate. Results: A total of 60 patients (29 diazepam, 31 placebo) completed pre- and postbiopsy surveys for analysis. The number of cores sampled during biopsy was controlled during analysis and was found to have no correlation with total pain measured. There were no differences between diazepam and placebo groups in age, prebiopsy survey results, immediate and 1 week postbiopsy survey results. There was no difference in the patients' willingness to undergo a repeated procedure in the control and treatment groups. Complications of taking diazepam prebiopsy included drowsiness, chills, and ankle injury. Conclusions: Diazepam does not improve patient pain perception immediately after or at 1-week recall after prostate biopsy. Omitting diazepam simplifies the biopsy regimen and allows the patient to drive himself home. Based on these results, routine use of diazepam in prostate biopsy is not recommended. PMID:24641687

Ultrasonography Performed by Primary Care Residents for Abdominal Aortic Aneurysm Screening  

PubMed Central

A prospective pilot study was undertaken to assess a protocol to educate primary care residents in how to personally perform ultrasonography for abdominal aortic aneurysm screening. Resident exams were proctored by a primary care physician trained in ultrasonography and were scored on the level of competence in doing the examination. Patients had ultrasound performed by a resident, followed by repeat examination by the vascular lab. Primary care resident abdominal aortic imaging was achieved in 79 of 80 attempts. Four abdominal aortic aneurysms were identified. There were 75 normal examinations; resident ultrasonography results were consistent with the results of the vascular lab. Ten residents achieved an abdominal aortic ultrasound-independent competence level after an average of 3.4 proctored exams. The main outcome of this study is that a primary care resident, with minimal training in ultrasonography imaging, is able to rapidly learn the technique of ultrasonography imaging of the abdominal aorta.

TRANSVAGINAL SONOGRAPHIC CERVICAL LENGTH FOR THE PREDICTION OF SPONTANEOUS PRETERM BIRTH IN TWIN PREGNANCIES: A SYSTEMATIC REVIEW AND METAANALYSIS  

PubMed Central

Objective To assess the accuracy of transvaginal sonographic cervical length (CL) in predicting spontaneous preterm birth in women with twin pregnancies. Study design Systematic review and metaanalysis of predictive test accuracy. Results Twenty-one studies (16 in asymptomatic women and 5 in symptomatic women) with a total of 3523 women met the inclusion criteria. Among asymptomatic women, a CL ?20 mm 20-24 weeks’ gestation was the most accurate in predicting preterm birth <32 and <34 weeks’ gestation (pooled sensitivities, specificities, and positive and negative likelihood ratios of 39% and 29%, 96% and 97%, 10.1 and 9.0, and 0.64 and 0.74, respectively). A CL ?25 mm 20-24 weeks’ gestation had a pooled positive likelihood ratio of 9.6 to predict preterm birth <28 weeks’ gestation. The predictive accuracy of CL for preterm birth was low in symptomatic women. Conclusion Transvaginal sonographic CL 20-24 weeks’ gestation is a good predictor of spontaneous preterm birth in asymptomatic women with twin pregnancies.

Transvaginal Cystocele Repair by Purse-String Technique Reinforced with Three Simple Sutures: Surgical Technique and Results  

PubMed Central

Purpose Different techniques for cystocele repair including the conventional anterior colporrhaphy and mesh technique are known. Our goal was to evaluate the anatomical success and safety of our method of transvaginal anterior vaginal wall repair by the purse-string technique reinforced with three simple additional sutures in the repair of cystocele over a 4-year follow-up period. Methods This was a retrospective review of 69 consecutive patients (grades 2 to 4) who underwent the above operations between 2001 and 2011, including their success rates as assessed by use of the Baden-Walker halfway classification system. Results Of the patients, 62 patients (98%) were completely cured of cystocele and 1 patient showed grade 2 cystocele recurrence that required no further treatment. Two patients with grade 4 cystocele were completely cured. There was no vaginal erosion related to the cystocele repair. Conclusions Transvaginal anterior colporrhaphy by a purse-string technique reinforced with simple additive sutures appears to be a simple, safe, and easily performed approach in cystocele repair. There is no need for other material for reinforcement, even in high-grade cystocele, which is an advantage of our technique.

Transvaginal ultrasound-guided cumulus oocyte complexes aspiration and in vitro embryo production in suckled beef and lactating dairy cattle on pasture-based management conditions.  

PubMed

This study was conducted to determine the use of repeated transvaginal ultrasound-guided cumulus oocyte complex (COC) aspiration on COC recovery rate, in vitro embryo production (IVP) and subsequent pregnancy rates in Holstein Friesian (HF) and Aberdeen Angus (AA) cows (Experiment 1), and in pregnant and non-pregnant Holstein Friesian cows (Experiment 2). Cycling, non-pregnant HF (n=17) and AA (n=32) cows with 40-70 days postpartum, between 3 and 5 years of age were used in the Experiment 1. All cows were submitted to repeated transvaginal ultrasound-guided COC aspiration twice a week for 5-7 weeks. Cumulus ooctye complexes (COC) were in vitro matured, fertilized and cultured for 8 days. An overall of 100 and 350 embryos from HF and AA cows respectively were cryopreserved using a conventional slow freezing (Experiment 1). A total of 81 and 285 frozen-thawed embryos from HF and AA cows respectively were transferred to recipient cows. Pregnancy diagnosis was performed at 60 and 150 days of gestation using transrectal ultrasonography. In Experiment 2, cycling non-pregnant (n=9) and pregnant (n=8) HF cows were submitted to repeated ultrasound-guided COC aspiration and COC were in vitro matured, fertilized and cultured as in Experiment 1, except that embryos were cryopreserved but not thawed and transferred as described for Experiment 1. The results of this study indicate that COC recovery rate and blastocyts production are affected by the breed of the donor cow. The quality of blastocyts produced from both breed did not differ in terms of pregnancy and calving rates (Experiment 1). The physiologic state of pregnancy did not affect COC recovery rate and blastocysts production per donor/session (Experiment 2). The use of ultrasound-guided COC aspiration and IVP could be a powerful technique to improve the genetic of beef and dairy cattle managed under pasture-based conditions management in the southern Chile.

Assessment of the fetal heart at 12-14 weeks of pregnancy using B-mode, color Doppler, and spatiotemporal image correlation via abdominal and vaginal ultrasonography.  

PubMed

This study aimed to evaluate the effect that combining multiple ultrasonographic imaging methods has on the proportion of tests with a satisfactory fetal heart assessment at 12-14 weeks of pregnancy using B-mode, color Doppler, and spatiotemporal image correlation software (STIC) via both the abdominal and vaginal routes. This cross-sectional prospective study involved healthy pregnant women at 12-14 weeks of pregnancy with a crown-rump length (CRL) of 84 mm or shorter. The following four cardiac views were assessed: four-chamber, left and right ventricular outflow tract, and aortic arch views. The same examiner sought to identify these four views using B-mode, color Doppler, and STIC via both the vaginal and abdominal routes. The study determined the proportion of cases and the respective 95 % confidence intervals (CIs) in which all four views were identified. The presence of significant differences in comparisons between methods was analyzed using McNemar's test. Although 57 pregnant women at 12-14 weeks of pregnancy agreed to participate in the study, 4 were not included because they presented with a CRL longer than 84 mm. Thus, 53 pregnant women were thoroughly assessed and included in the analysis. The combination of B-mode, color Doppler, and STIC via both the abdominal and vaginal routes enabled the highest proportion of identification of the four views (90.6 %; 95 % CI, 79.8-95.9 %). The lowest proportions were observed when B-mode was used alone via both the vaginal route (30.2 %; 95 % CI, 19.5-43.5 %) and the abdominal route (37.7 %; 95 % CI, 25.9-51.2 %). The abdominal route showed results slightly better than those of the vaginal route with all the methods, but the differences were not statistically significant. In the vast majority of the cases, the fetal hearts were properly assessed at 12-14 weeks of pregnancy when several methods were combined using both the abdominal and vaginal routes. However, only one-third of them would have had adequate heart assessment if the B-mode via either the abdominal or the vaginal route had been used alone. PMID:23479309

PubMed

We performed hysterosalpingography (HSG) and transvaginal ultrasound (TVU) in 124 Ivorian women as part of an infertility evaluation. The aim was to investigate the causes of infertility and show the advantages of combining HSG and TVU as part of a comprehensive evaluation of infertility in African woman. TVU and HSG were normal in 35.5% of cases, while in 64.5% of cases, at least one disease was demonstrated. This included uterine pathology in 50.3%, tubal disease in 25.2%, ovarian pathology in 7.5% and peritoneal pathology in 7% of cases. Of all the diseases identified by the association HSG and TVU, 71.3% were found by TVU, while 61.5% were confirmed by HSG. TVU was more efficient in identifying uterine and ovarian pathologies while HSG excelled in tubal pathology. HSG and TUV had identical performances on the peritoneal pathology. The association HSG-ETV should be systematic in the full assessment of female infertility in sub-Saharan Africa. PMID:23444542

High-resolution breast ultrasonography.  

PubMed

Recent improvements in ultrasonic-scanning now permit solid tumors in the breast as small as 5 mm and cystic lesions of 2mm in size to be detected. The overall accuracy of diagnostic ultrasound is very high, and as more experience is gained by application of newer high-resolution systems this accuracy will improve even further. In certain cases, ultrasonography can detect lesions completely missed by clinical palpation. In some areas such as cystic lesions this modality is far superior to the mammograph and in other situations it complements other diagnostic procedures. Areas of microcalcification may be localized. Cystic lesions of the breast are not easily diagnosed with great accuracy. In our extensive experience over the past 4 years, fibroadenomas generally appear as sharply marginated spherical or lobulated masses with an echopoor center and high through transmission. Carcinoma tends to attenuate sound energy highly and frequently produces a characteristic echo pattern. Fibrous dysplasia appears as a highly echogenic zone which is readily distinguished from other entities. Contact ultrasonography is used to localize the lesion three-dimensionally within the breast for biopsy purposes and to detect the presence of distant metastases. PMID:7215116

In the rheumatology literature, most of the available evidence on three-dimensional ultrasound (3D US) is related to the acquisition process and highlights the virtual operator independence and shortening of the US examination time. The main aim of this study was to compare 3D US using a high-frequency volumetric probe and conventional 2D US at the wrist and hand in patients with rheumatoid arthritis (RA). The 3D US examinations were performed using a Logiq 9 (General Electrics Medical Systems, Milwaukee, WI) with a high-frequency (8-15 MHz) volumetric probe. Overall, there is good-to-excellent agreement between the two modalities relating to both joint inflammation and bone erosion. This study is an initial step towards establishing a methodology necessary for developing multi-centre US studies which are aimed at assessing hand involvement in patients with RA. PMID:19473557

Long-term results of transvaginal colposuspension for the treatment of genuine stress incontinence combined with vaginal hysterectomy.  

PubMed

We assessed the long-term efficacy of a modified transvaginal needle bladder neck suspension, combined with vaginal hysterectomy, for the treatment of female stress incontinence. Thirty-two women who underwent this procedure were followed up clinically and urodynamically 1 and 5 years postoperatively. A total of 27 women (84.4%) were cured 1 year postoperatively. Of the 29 women who were followed up 5 years postoperatively, 21 (72.4%) had a satisfactory result (p = 0.157). No significant differences were observed in maximum urine flow rate, residual volume of urine, and functional length of the urethra. On the contrary, the maximum urethral closure pressure was significantly decreased (p = 0.004). Although the results of our study show a decline in success rate by time, the overall long-term efficacy of this technique is undoubtedly satisfactory. This technique is promising as an easy and minimally invasive surgical procedure for bladder neck suspension. PMID:12845259

Managing chronic pelvic pain following reconstructive pelvic surgery with transvaginal mesh.  

PubMed

In 2001, the US Food and Drug Administration (FDA) approved the first transvaginal mesh kit to treat pelvic organ prolapse (POP). Since the introduction of vaginal mesh kits, some vaginal meshes have been associated with chronic pelvic pain after reconstructive pelvic floor surgery. Pelvic pain results in between 0 % and 30 % of patients following transvaginal mesh placement. Common causes of chronic pelvic pain include pelvic floor muscle spasm, pudendal neuralgia, and infection. Paucity of data exists on the effective management of chronic pelvic pain after pelvic reconstructive surgery with mesh. We outline the management of chronic pelvic pain after transvaginal mesh placement for reconstructive pelvic floor repair based on our clinical experience and adaptation of data used in other aspects of managing chronic pelvic pain conditions.

Obese women's perception of bariatric trans-vaginal NOTES.  

PubMed

Much of the discussion pertaining to natural orifice transluminal endoscopic surgery (NOTES) focuses on technical issues, with little attention to women's perception and to their willingness to consent to this surgery, especially in the field of obesity. Aim of this study was to evaluate obese women's perception of NOTES and trans-vaginal access. Sixty two obese patients undergoing bariatric surgery were given a written description of NOTES with an anonymous questionnaire exploring their concerns and opinions regarding this technique. The risk of complications was the most important aspect with regard to surgical procedures for 87.1% of patients, while the aesthetic result counted only for 16.1%; none of the patients would accept an increased risk of surgical complications for a better aesthetic result, and 74.2% of them would prefer a standardized traditional surgical approach. Nulliparous women were more concerned about the potentially negative effects of NOTES on fertility than multiparous women and younger women were more worried about the effects on sexual function than older women. 83.9% of patients refusing NOTES stated that the main reason for their refusal was the lack of definitive data on the beneficial effects. Bariatric NOTES potentially offers obese women a scarless intervention, but only a few obese women expressed worries about the cosmetic/aesthetic effects of surgery, while most of them were worried about effects on future fertility and sexual life. Our study highlights a strong need for early reporting of outcome data to enlighten patients about this new approach to bariatric surgery. PMID:22170394

[Diagnostic ability of ultrasonography for the rotator cuff tear: comparison with ultrasonography and MRI findings].  

PubMed

Ultrasonography (US) is a non-invasive method which can assess not only solid tissue organs but also soft tissues such as tendons and nerves. However, it has not been fully understood that US is a useful tool for the depiction of periarticular structure. We compared the diagnostic accuracies between US and magnetic resonance imaging (MRI) in the patients with rotator cuff tear (RCT). Seventy patients, who underwent arthroscopic surgery, preoperative US and MRI examinations at Gifu University Hospital from January 2010 to April 2013 (49 male, 21 female, mean age 59.7 +/- 15.9) were included in this study. The diagnostic accuracy, sensitivity and specificity of US and MRI were 94.3% and 94.3%, 95.8% and 97.9%, 90.9% and 84.6%, respectively, when the intraoperative finding was regarded as a gold standard. These results suggest that US is useful for the diagnosis of RCT as equal as MRI. PMID:24724424

Assessment of cross-sectional thickness and activity of masseter, anterior temporalis and orbicularis oris muscles in oral submucous fibrosis patients and healthy controls: an ultrasonography and electromyography study.  

PubMed

Objectives: Oral submucous fibrosis (OSMF) is an insidious chronic disease that is associated with significant functional morbidity and an increased risk for malignancy. It initially affects the lamina propria of the oral mucosa, and, as the disease progresses, it involves the submucosa and deeper tissue, including muscles of the oral cavity, resulting in loss of fibroelasticity. OSMF is a pre-malignant condition mainly caused by areca nut chewing. The aim of this study was to find out the involvement of muscles of mastication and facial expression in patients with OSMF by assessing the cross-sectional thickness and activity of the masseter, anterior temporalis and orbicularis oris muscles by ultrasonography and electromyography and comparing with healthy controls and also to find out any correlation between the ultrasonographic cross-sectional thicknesses of the masseter, anterior temporalis and orbicularis oris muscles with electromyographic activity. Methods: 40 patients with OSMF were included in the study group, and the patients were divided into four groups on the basis of interincisal mouth opening, i.e. Group I (mouth opening >35?mm), Group II (mouth opening between 30 and 35?mm), Group III (mouth opening between 20 and 30?mm) and Group IV (mouth opening <20?mm). Ultrasonographic cross-sectional thickness and electromyographic activity (amplitude and duration) of the masseter, anterior temporalis and orbicualris oris muscles were recorded in patients with OSMF and 20 controls. Intergroup comparison of ultrasonographic cross-sectional thickness and activity (amplitude and duration) was done, and Pearson's correlation coefficient was applied to find out any relation between ultrasonographic and electromyographic findings. Results: Thickness and activity of the masseter muscle was significantly reduced in Group IV (mouth opening <20?mm) when compared with the control group. The anterior temporalis and orbicularis oris muscles remained unaffected. A positive correlation was observed between the thicknesses of the masseter muscle and the amplitude in Groups I, II and III; the anterior temporalis muscle in Group II and the control group; and the orbicularis oris muscle in Groups II, III and IV. Conclusions: It was concluded that, among the muscles studied, there was an early involvement of the masseter muscle in patients with OSMF compared with that of other muscles. PMID:24720604

Transvaginal specimen extraction after combined laparoscopic splenectomy and hysterectomy: Introduction to NOSE (Natural Orifice Specimen Extraction) in a community hospital?  

PubMed Central

INTRODUCTION Developments in the field of minimally invasive surgery have led to interest in NOTES (natural orifice transluminal endoscopic surgery). Even as technologies continue to evolve and develop, interest in some of the advantages of specimen retrieval transvaginally has been roused and we describe a case of combined laparoscopic splenectomy and hysterectomy with transvaginal retrieval of both specimens. PRESENTATION OF CASE Patient underwent laparoscopic splenectomy and robot-assisted hysterectomy with transvaginal delivery of specimens. Total operative time was 245 min with no complications. Closure of the colpotomy was achieved laparoscopically. Post-operative course was unremarkable. Patient has done well clinically at 18 months follow-up except for an episode of post-coital spotting, which resolved spontaneously. DISCUSSION We explored the technical feasibility of concurrent laparoscopic splenectomy and hysterectomy along with transvaginal retrieval of both solid organs without morcellation. We wanted to illustrate the fact that transvaginal organ extraction may be performed safely in a community or district hospital with standard instruments without incurring additional cost, morbidity or increased operating time. CONCLUSION Transvaginal specimen retrieval was technically easy to accomplish. Our patient has not experienced any infectious complications or sexual dysfunction to date. For surgeons exploring an alternative to transabdominal specimen retrieval, transvaginal NOSE is an attractive proposition with several advantages. When combined with a gynecological procedure that involves a colpotomy, this may present a unique opportunity to explore the utility of NOSE.

Persistence of Microbial Contamination on Transvaginal Ultrasound Probes despite Low-Level Disinfection Procedure  

PubMed Central

Aim of the Study In many countries, Low Level Disinfection (LLD) of covered transvaginal ultrasound probes is recommended between patients' examinations. The aim of this study was to evaluate the antimicrobial efficacy of LLD under routine conditions on a range of microorganisms. Materials and Methods Samples were taken over a six month period in a private French Radiology Center. 300 specimens derived from endovaginal ultrasound probes were analyzed after disinfection of the probe with wipes impregnated with a quaternary ammonium compound and chlorhexidine. Human papillomavirus (HPV) was sought in the first set of s100 samples, Chlamydia trachomatis and mycoplasmas were searched in the second set of 100 samples, bacteria and fungi in the third 100 set samples. HPV, C. trachomatis and mycoplasmas were detected by PCR amplification. PCR positive samples were subjected to a nuclease treatment before an additional PCR assay to assess the likely viable microorganisms. Bacteria and fungi were investigated by conventional methods. Results A substantial persistence of microorganisms was observed on the disinfected probes: HPV DNA was found on 13% of the samples and 7% in nuclease-resistant form. C. trachomatis DNA was detected on 20% of the probes by primary PCR but only 2% after nuclease treatment, while mycoplasma DNA was amplified in 8% and 4%, respectively. Commensal and/or environmental bacterial flora was present on 86% of the probes, occasionally in mixed culture, and at various levels (10->3000 CFU/probe); Staphylococcus aureus was cultured from 4% of the probes (10-560 CFU/probe). No fungi were isolated. Conclusion Our findings raise concerns about the efficacy of impregnated towels as a sole mean for disinfection of ultrasound probes. Although the ultrasound probes are used with disposable covers, our results highlight the potential risk of cross contamination between patients during ultrasound examination and emphasize the need for reviewing the disinfection procedure.

Bedside ultrasonography-Applications in critical care: Part II  

PubMed Central

Point of care ultrasonography, performed by acute care physicians, has developed into an invaluable bedside tool providing important clinical information with a major impact on patient care. In Part II of this narrative review, we describe ultrasound guided central venous cannulation, which has become standard of care with internal jugular vein cannulation. Besides improving success rates, real-time guidance also significantly reduces the incidence of complications. We also discuss compression ultrasonography - a quick and effective bedside screening tool for deep vein thrombosis of the lower extremity. Abdominal ultrasound offers vital clues in the emergency setting; in the unstable trauma victim, a focused examination may provide immediate answers and has largely superseded diagnostic peritoneal lavage in diagnosing intraperitoneal bleed. From estimation of intracranial pressure to transcranial Doppler studies, ultrasound is becoming increasingly relevant to neurocritical care. Ultrasound may also help with airway management in several situations, including percutaneous tracheostomy. Clearly, bedside ultrasonography has become an indispensable part of intensive care practice – in the rapid assessment of critically ill-patients as well as in enhancing the safety of invasive procedures.

Bedside ultrasonography: Applications in critical care: Part I  

PubMed Central

There is increasing interest in the use of ultrasound to assess and guide the management of critically ill patients. The ability to carry out quick examinations by the bedside to answer specific clinical queries as well as repeatability are clear advantages in an acute care setting. In addition, delays associated with transfer of patients out of the Intensive Care Unit (ICU) and exposure to ionizing radiation may also be avoided. Ultrasonographic imaging looks set to evolve and complement clinical examination of acutely ill patients, offering quick answers by the bedside. In this two-part narrative review, we describe the applications of ultrasonography with a special focus on the management of the critically ill. Part I explores the utility of echocardiography in the ICU, with emphasis on its usefulness in the management of hemodynamically unstable patients. We also discuss lung ultrasonography - a vastly underutilized technology for several years, until intensivists began to realize its usefulness, and obvious advantages over chest radiography. Ultrasonography is rapidly emerging as an important tool in the hands of intensive care physicians.

Portable ultrasonography in mass casualty incidents: The CAVEAT examination  

PubMed Central

Ultrasonography used by practicing clinicians has been shown to be of utility in the evaluation of time-sensitive and critical illnesses in a range of environments, including pre-hospital triage, emergency department, and critical care settings. The increasing availability of light-weight, robust, user-friendly, and low-cost portable ultrasound equipment is particularly suited for use in the physically and temporally challenging environment of a multiple casualty incident (MCI). Currently established ultrasound applications used to identify potentially lethal thoracic or abdominal conditions offer a base upon which rapid, focused protocols using hand-carried emergency ultrasonography could be developed. Following a detailed review of the current use of portable ultrasonography in military and civilian MCI settings, we propose a protocol for sonographic evaluation of the chest, abdomen, vena cava, and extremities for acute triage. The protocol is two-tiered, based on the urgency and technical difficulty of the sonographic examination. In addition to utilization of well-established bedside abdominal and thoracic sonography applications, this protocol incorporates extremity assessment for long-bone fractures. Studies of the proposed protocol will need to be conducted to determine its utility in simulated and actual MCI settings.

Ultrasonography of the omasum in 30 Saanen goats  

PubMed Central

Background Primary diseases of the omasum are uncommon in goats, although the omasum may be involved in various gastrointestinal disorders. Examination of the caprine omasum via ultrasonography requires a good understanding of the normal appearance of the organ. However, in contrast to cattle, there is a lack of reference information on this topic in goats. Thus, the goal of the present study was to describe the results of ultrasonography of the omasum in 30 healthy Saanen goats. Results Ultrasonography was carried out in standing, non-sedated goats using a 5.0 MHz linear transducer. The location and size of the omasum, thickness of the omasal wall and visualisation of the abomasal laminae, contents and contractions were assessed. The omasum was visible from the 9th intercostal space (ICS) in all the goats, and from the 8th and 10th ICSs in 29 and 24 goats, respectively. The omasum was seen medial to the liver, but only the omasal wall closest to the transducer was visible. The dorsal omasal limit formed a dorsally convex curve running from cranioventral to caudodorsal and was furthest from the dorsal midline in the 6th ICS. The ventral omasal limit formed a ventrally convex curve. The size of the omasum was largest (10.2 ± 3.1 cm) in the 9th ICS and decreased cranially and caudally from this position. Active omasal motility was recorded in 20 goats with 0.3 to 2.0 contractions per minute. Conclusions The findings of this study provide reference ranges for the interpretation of the location and size of the omasum in goats with suspected omasal abnormalities. Ultrasonography is an ideal diagnostic tool for evaluation of the omasum, which is not accessible to conventional examination techniques, such as inspection, palpation, percussion and auscultation.

Diagnostic Performance and Reliability of Ultrasonography for Fatty Degeneration of the Rotator Cuff Muscles  

PubMed Central

Background: Diagnostic evaluation of rotator cuff muscle quality is important to determine indications for potential operative repair. Ultrasonography has developed into an accepted and useful tool for evaluating rotator cuff tendon tears; however, its use for evaluating rotator muscle quality has not been well established. The purpose of this study was to investigate the diagnostic performance and observer reliability of ultrasonography in grading fatty degeneration of the posterior and superior rotator cuff muscles. Methods: The supraspinatus, infraspinatus, and teres minor muscles were prospectively evaluated with magnetic resonance imaging (MRI) and ultrasonography in eighty patients with shoulder pain. The degree of fatty degeneration on MRI was graded by four independent raters on the basis of the modified Goutallier grading system. Ultrasonographic evaluation of fatty degeneration was performed by one of three radiologists with use of a three-point scale. The two scoring systems were compared to determine the diagnostic performance of ultrasonography. The interobserver and intraobserver reliability of MRI grading by the four raters were determined. The interobserver reliability of ultrasonography among the three radiologists was determined in a separate group of thirty study subjects. The weighted Cohen kappa, percentage agreement, sensitivity, and specificity were calculated. Results: The accuracy of ultrasonography for the detection of fatty degeneration, as assessed on the basis of the percentage agreement with MRI, was 92.5% for the supraspinatus and infraspinatus muscles and 87.5% for the teres minor. The sensitivity was 84.6% for the supraspinatus, 95.6% for the infraspinatus, and 87.5% for the teres minor. The specificity was 96.3% for the supraspinatus, 91.2% for the infraspinatus, and 87.5% for the teres minor. The agreement between MRI and ultrasonography was substantial for the supraspinatus and infraspinatus (kappa = 0.78 and 0.71, respectively) and moderate for the teres minor (kappa = 0.47). The interobserver reliability for MRI was substantial for the supraspinatus and infraspinatus (kappa = 0.76 and 0.77, respectively) and moderate for the teres minor (kappa = 0.59). For ultrasonography, the interobserver reliability was substantial for all three muscles (kappa = 0.71 for the supraspinatus, 0.65 for the infraspinatus, and 0.72 for the teres minor). Conclusions: The diagnostic performance of ultrasonography in identifying and grading fatty degeneration of the rotator cuff muscles was comparable with that of MRI. Ultrasonography can be used as the primary diagnostic imaging modality for fatty changes in rotator cuff muscles. Level of Evidence: Diagnostic Level II. See Instructions for Authors for a complete description of levels of evidence.

Ultrasonography in diagnosing chronic pancreatitis: new aspects.  

PubMed

The course and outcome is poor for most patients with pancreatic diseases. Advances in pancreatic imaging are important in the detection of pancreatic diseases at early stages. Ultrasonography as a diagnostic tool has made, virtually speaking a technical revolution in medical imaging in the new millennium. It has not only become the preferred method for first line imaging, but also, increasingly to clarify the interpretation of other imaging modalities to obtain efficient clinical decision. We review ultrasonography modalities, focusing on advanced pancreatic imaging and its potential to substantially improve diagnosis of pancreatic diseases at earlier stages. In the first section, we describe scanning techniques and examination protocols. Their consequences for image quality and the ability to obtain complete and detailed visualization of the pancreas are discussed. In the second section we outline ultrasonographic characteristics of pancreatic diseases with emphasis on chronic pancreatitis. Finally, new developments in ultrasonography of the pancreas such as contrast enhanced ultrasound and elastography are enlightened. PMID:24259955

Thoracic ultrasonography for the pulmonary specialist.  

PubMed

Thoracic ultrasonography is a noninvasive and readily available imaging modality that has important applications in pulmonary medicine outside of the ICU. It allows the clinician to diagnose a variety of thoracic disorders at the point of care. Ultrasonography is useful in imaging lung consolidation, pleural-based masses and effusions, pneumothorax, and diaphragmatic dysfunction. It can identify complex or loculated effusions and be useful in planning treatment. Identifying intrathoracic mass lesions can guide sampling by aspiration and biopsy. This article summarizes thoracic ultrasonography applications for the pulmonary specialist, related procedural codes, and reimbursement. The major concepts are illustrated with cases. These case summaries are enhanced with online supplemental videos and chest radiograph, chest CT scan, and ultrasound correlation. PMID:22045878

Sources of error in emergency ultrasonography  

PubMed Central

Background To evaluate the common sources of diagnostic errors in emergency ultrasonography. Methods The authors performed a Medline search using PubMed (National Library of Medicine, Bethesda, Maryland) for original research and review publications examining the common sources of errors in diagnosis with specific reference to emergency ultrasonography. The search design utilized different association of the following terms : (1) emergency ultrasonography, (2) error, (3) malpractice and (4) medical negligence. This review was restricted to human studies and to English-language literature. Four authors reviewed all the titles and subsequent the abstract of 171 articles that appeared appropriate. Other articles were recognized by reviewing the reference lists of significant papers. Finally, the full text of 48 selected articles was reviewed. Results Several studies indicate that the etiology of error in emergency ultrasonography is multi-factorial. Common sources of error in emergency ultrasonography are: lack of attention to the clinical history and examination, lack of communication with the patient, lack of knowledge of the technical equipment, use of inappropriate probes, inadequate optimization of the images, failure of perception, lack of knowledge of the possible differential diagnoses, over-estimation of one’s own skill, failure to suggest further ultrasound examinations or other imaging techniques. Conclusions To reduce errors in interpretation of ultrasonographic findings, the sonographer needs to be aware of the limitations of ultrasonography in the emergency setting, and the similarities in the appearances of various physiological and pathological processes. Adequate clinical informations are essential. Diagnostic errors should be considered not as signs of failure, but as learning opportunities.

Development of a chute to facilitate transvaginal ultrasound guided oocyte aspiration (TUGA) in the sow.  

PubMed

A procedure developed for nonsurgical transvaginal ultrasound-guided oocyte aspiration in the mature sow was dependent upon development of a special chute. This chute was designed to immobilize and protect the sow. The floor of the chute possessed a metal bar that was elevated via a hydraulic lift until the weight of the sow rested on the bar, while her hooves were still in contact with the floor. This exact positioning of the female prevented her from resisting procedure and allowed for a comfortable setting for technician to manipulate the ovaries (per rectum) and perform transvaginal ultrasound guided oocyte aspiration (TUGA). Oocyte collection was performed in six sows, and none experienced detrimental health effects from the procedure. PMID:22986298

Diagnostic utility of combined ultrasonography and mammography in the evaluation of women with mammographically dense breasts  

PubMed Central

Purpose To assess the diagnostic utility and additional cost of combined breast ultrasonography and mammography in the evaluation of asymptomatic women with mammographically dense breasts. Materials and methods Of 5108 asymptomatic women, who underwent mammography, 1754 had dense breasts (BI-RADS 3 or 4) and negative mammographic outcome. They were divided in 4 subgroups according to their age (<40 yrs; 40–49 yrs; 50–59 yrs; >59 yrs). Breast ultrasonography was performed immediately after mammography. Lesions detected at ultrasonography were examined cytologically/histologically. Mammograms from women, who were diagnosed carcinoma at ultrasonography, were reviewed by an external radiologist. Costs per diagnosed carcinoma and per examined woman were calculated on the basis of current regional charges. Results Mammographies (5108) were performed, 67 cancers were detected (cancer detection rate 13.1‰): mammography identified 55 carcinomas and ultrasonography performed in women with dense breasts identified 12 cancers (17.9% of all cancers detected, overall cancer detection rate 6.8‰). Ultrasonography identified a benign condition in 1567 out of 1754 women (89.3%) (in 925 absence of focal lesions; 438 simple cysts; 56 ductal ectasia; 148 benign solid lesions); 97 complex cysts, 52 lesions that could not be differentiated as liquid or solid lesions, and 38 solid lesions suspicious for malignancy in the remaining 187 out of 1754 patients (10.7%). Cytology/histology confirmed carcinoma in 12 women (overall biopsy rate 26.2‰, benign biopsy rate 19.4‰). The additional costs were: € 6,123.45 per detected cancer, € 41.89 per examined woman. Conclusion Breast ultrasonography immediately after mammography in women with dense breasts is useful to avoid diagnostic delays and inconvenient medico-legal implications even though this procedure involves increased costs.

Twin pregnancy experimental model for transvaginal ultrasound-guided twin reduction in mares  

PubMed Central

Multiple pregnancies are still an important cause of noninfectious abortion, stillbirth, neonatal mortality, and significant delays in reproductive performance in mares. Despite new management techniques, reduction in multiple pregnancies is an ongoing preoccupation and challenge for the equine veterinarian. The aim of the present study was to establish a twin pregnancy experimental model in the mare to study the effectiveness of a transvaginal ultrasound-guided embryonic vesicle injection. Mares in heat were inseminated and then received an embryo at day 7 of the estrous cycle. At days 14 and 30, 53.5% (n = 23) and 23% (n = 10) of the mares, respectively, were carrying twins. Twin pregnancies were reduced at day 30 by transvaginal ultrasound-guided puncture of the embryonic vesicle (control, n = 5) or by transvaginal ultrasound-guided injection (TVUEVI) of 25 mg of amikacin into the embryonic vesicle (n = 5). The TVUEVI treatment had a 40% success rate and no significant variations in progesterone and prostaglandin metabolite were observed. Even though the technique does not seem very effective, the experimental model could be useful for clinical research in embryo reduction and early embryonic loss.

Surgical repair of rectocele. Comparison of transvaginal and transanal approach and personal technique  

PubMed Central

Summary Rectocele is defined as a herniation of the rectal wall inside the vagina due to a defect of the recto-vaginal septum. It is traditionally considered a posterior compartment damage with weakness of posterior vaginal wall support resulting in a bulging of the rectum into the vaginal cavity. One of the main causes of rectal prolapse is the operative vaginal birth, although the evidence of the defect may occur after many years The treatment of rectocele is surgical, and the approach can be transperineal, transvaginal, and transanal or, in selected cases, transperitoneal through open or laparoscopic techniques. In this study we compare two transvaginal surgical techniques - i.e. the perineal body anchorage to the posterior septum and the traditional Denonvilliers’ transversal suture after removing of the vaginal skin, with the mostly performed transanal procedure, the STARR - comparing the data from the literature on their results. Mean hospital stay, rectal symptoms, dyspareunia, quality of life, recurrence rate and postoperative complications have been considered. Both transvaginal and transrectal surgical techniques are effective to solve posterior compartment defect and to improve the quality of life. Vaginal approach may interfere with the sexual activity; furthermore it is associated with minimal postoperative pain than the transanal approach. Better anatomic results are assured after endovaginal surgery, while better rectal function prevail after the transanal approach. Vaginal techniques are more suitable to gynecologists, whereas the transrectal ones are usually performed by colo-proctologists or general surgeons.

Transabdominal Ultrasonography of the Small Bowel  

PubMed Central

In the era of double balloon enteroscopy, capsule endoscopy, CT, and MRI enterography is transabdominal ultrasonography (TUS) underestimated method for evaluation of small bowel pathology. As often initial imagine method in abdominal complaints, nowadays has TUS much better diagnostic potential than two decades ago. High-resolution ultrasound probes with harmonic imaging significantly improve resolution of bowel wall in real time, with possibility to asses bowel peristalsis. Color flow doppler enables evaluation of intramural bowel vascularisation, pulse wave doppler helps to quantificate flow in coeliac and superior mesenteric arteries. Small intestine contrast ultrasonography with oral contrast fluid, as well as contrast enhanced ultrasonography with intravenous microbubble contrast also improves small bowel imaging. We present a review of small intestine pathology that should be detected during ultrasound examinations, discuss technical requirements, advantages and limitations of TUS, typical ultrasound signs of Crohn's disease, ileus, celiac disease, intussusception, infectious enteritis, tumours, ischemic and haemorrhagic conditions of small bowel. In the hands of experienced investigator, despite some significant limitations(obesity, meteorism), is transabdominal ultrasonography reliable, noninvasive and inexpensive alternative method to computerised tomography (CT) and magnetic resonance imaging (MRI) in small bowel examination.

Ultrasonography survey and thyroid cancer in the Fukushima Prefecture.  

PubMed

Thyroid cancer is one of the major health concerns after the accident in the Fukushima Dai-ichi nuclear power station (NPS). Currently, ultrasonography surveys are being performed for persons residing in the Fukushima Prefecture at the time of the accident with an age of up to 18 years. Here, the expected thyroid cancer prevalence in the Fukushima Prefecture is assessed based on an ultrasonography survey of Ukrainians, who were exposed at an age of up to 18 years to (131)I released during the Chernobyl NPS accident, and on differences in equipment and study protocol in the two surveys. Radiation risk of thyroid cancer incidence among survivors of the atomic bombings of Hiroshima and Nagasaki and preliminary estimates of thyroid dose due to the Fukushima accident were used for the prediction of baseline and radiation-related thyroid cancer risks. We estimate a prevalence of thyroid cancer of 0.027 % (95 % CI 0.010 %; 0.050 %) for the first screening campaign in the Fukushima Prefecture. Compared with the incidence rate in Japan in 2007, the ultrasonography survey is predicted to increase baseline thyroid cancer incidence by a factor of 7.4 (95 % CI 0.95; 17.3). Under the condition of continued screening, thyroid cancer during the first fifty years after the accident is predicted to be detected for about 2 % of the screened population. The prediction of radiation-related thyroid cancer in the most exposed fraction (a few ten thousand persons) of the screened population of the Fukushima Prefecture has a large uncertainty with the best estimates of the average risk of 0.1-0.3 %, depending on average dose.

Ultrasonography of the metacarpophalangeal and proximal interphalangeal joints in rheumatoid arthritis: a comparison with magnetic resonance imaging, conventional radiography and clinical examination  

PubMed Central

Signs of inflammation and destruction in the finger joints are the principal features of rheumatoid arthritis (RA). There are few studies assessing the sensitivity and specificity of ultrasonography in detecting these signs. The objective of the present study was to investigate whether ultrasonography can provide information on signs of inflammation and destruction in RA finger joints that are not available with conventional radiography and clinical examination, and comparable to the information provided by magnetic resonance imaging (MRI). The second to fifth metacarpophalangeal and proximal interphalangeal joints of 40 RA patients and 20 control persons were assessed with ultrasonography, clinical examination, radiography and MRI. With MRI as the reference method, the sensitivity, specificity and accuracy of ultrasonography in detecting bone erosions in the finger joints were 0.59, 0.98 and 0.96, respectively; they were 0.42, 0.99 and 0.95 for radiography. The sensitivity, specificity and accuracy of ultrasonography, with signs of inflammation on T1-weighted MRI sequences as the reference method, were 0.70, 0.78 and 0.76, respectively; they were 0.40, 0.85 and 0.72 for the clinical examination. With MRI as the reference method, ultrasonography had higher sensitivity and accuracy in detecting signs of inflammation and destruction in RA finger joints than did clinical and radiographic examinations, without loss of specificity. This study shows that ultrasonography has the potential to improve assessment of patients with RA.

Endoscopic ultrasonography (EUS) technology has undergone a great deal of progress along with the color and power Doppler imaging, three-dimensional imaging, electronic scanning, tissue harmonic imaging, and elastography, and one of the most important developments is the ability to acquire contrast-enhanced images. The blood flow in small vessels and the parenchymal microvasculature of the target lesion can be observed non-invasively by contrast-enhanced EUS (CE-EUS). Through a hemodynamic analysis, CE-EUS permits the diagnosis of various gastrointestinal diseases and differential diagnoses between benign and malignant tumors. Recently, mechanical innovations and the development of contrast agents have increased the use of CE-EUS in the diagnostic field, as well as for the assessment of the efficacy of therapeutic agents.

Mesh exposure and associated risk factors in women undergoing transvaginal prolapse repair with mesh.  

PubMed

Objective. To determine frequency, rate, and risk factors associated with mesh exposure in women undergoing transvaginal prolapse repair with polypropylene mesh. Methods. Retrospective chart review was performed for all women who underwent Prolift Pelvic Floor Repair System (Gynecare, Somerville, NJ) between September 2005 and September 2008. Multivariable logistic regression was performed to identify risk factors for mesh exposure. Results. 201 women underwent Prolift. Mesh exposure occurred in 12% (24/201). Median time to mesh exposure was 62 days (range: 10-372). When mesh was placed in the anterior compartment, the frequency of mesh exposure was higher than that when mesh was placed in the posterior compartment (8.7% versus 2.9%, P = 0.04). Independent risk factors for mesh exposure were diabetes (AOR?=?7.7, 95% CI 1.6-37.6; P = 0.01) and surgeon (AOR?=?7.3, 95% CI 1.9-28.6; P = 0.004). Conclusion. Women with diabetes have a 7-fold increased risk for mesh exposure after transvaginal prolapse repair using Prolift. The variable rate of mesh exposure amongst surgeons may be related to technique. The anterior vaginal wall may be at higher risk of mesh exposure as compared to the posterior vaginal wall. PMID:24194763

Necrotising fasciitis after hysterectomy and concomitant transvaginal mesh repair in a patient with pelvic organ prolapse.  

PubMed

Necrotising fasciitis is a severe form of soft tissue infection. Herein, we present an unreported complication of the transvaginal repair of a pelvic organ prolapse (POP) with trocar-guided polypropylene mesh and a concomitant hysterectomy. A 61-year-old Caucasian female who had been using an intrauterine device (IUD) for 30 years presented with a stage 3 pelvic organ prolapse. A genital ultrasound examination confirmed the presence of an IUD, but found no endometrial abnormalities. The surgical management was limited to a transvaginal hysterectomy and simultaneous anterior vaginal wall repair augmented with trocar-guided mesh. A morphological examination of the removed uterus confirmed the presence of the intrauterine device and additionally found endometrial cancer (T1N0M0), which was not revealed during the preoperative ultrasound. Within 6 days of the surgery, she developed anaerobic bilateral necrotising fasciitis on both thighs. Non-clostridial streptococci were identified in the wound. After 18 days of intensive care, the patient died of fatal coagulopathy. PMID:23389641

Laparoscopy with laparoscopic ultrasonography in the TNM staging of pancreatic carcinoma.  

PubMed

A prospective study was performed comparing laparoscopy with laparoscopic ultrasonography (LapUS), transabdominal ultrasonography (USS), computed tomography (CT), and selective visceral angiography with portal phase venography (SVA) for the assessment of resectability in 50 patients with pancreatic or periampullary cancer. The results were stratified by TNM stages. Tumor unresectability was demonstrated in 36 patients (72%). The sensitivity of LapUS for demonstrating the index lesion was 96%. Laparoscopic ultrasonography failed to predict factors precluding resection by T stage in six patients, and there were no significant differences in the ability of any modality to predict local resectability (predictive value 58-73%). Laparoscopic ultrasonography did not overestimate T stage and was significantly more specific for assessing unresectability compared with USS (100% vs. 64%, p<0.05) and CT (100% vs. 47%, p<0.005). No imaging investigation was able to assess the N stage accurately. Metastases were confirmed in 16 patients (32%), with LapUS proving significantly more sensitive than USS (94% vs. 29%, p<0.001) and CT (94% vs. 33%, p<0.005). The addition of LapUS to the laparoscopic examination did not change the M stage in any patient, as all metastases were superficially located. Laparoscopy with LapUS was the most reliable method for assessing overall tumour resectability and was significantly more predictive than CT (97% vs. 79%, p<0.005). These results confirm that laparoscopy is indispensable for detecting occult intraabdominal metastases. LapUS reliably predicts tumor unresectability, offsetting the tendency of USS and CT to overestimate T stage. Methods of accurate N staging remain elusive, and the use of routine SVA is not justified. PMID:10449813

Pretreatment Evaluation with Contrast-Enhanced Ultrasonography for Percutaneous Radiofrequency Ablation of Hepatocellular Carcinomas with Poor Conspicuity on Conventional Ultrasonography  

PubMed Central

Objective To determine whether pretreatment evaluation with contrast-enhanced ultrasonography (CEUS) is effective for percutaneous radiofrequency ablation (RFA) of hepatocellular carcinoma (HCC) with poor conspicuity on conventional ultrasonography (US). Materials and Methods This retrospective study was approved by the institutional review board and informed consent was waived. From June 2008 to July 2011, 82 patients having HCCs (1.2 ± 0.4 cm) with poor conspicuity on planning US for RFA were evaluated with CEUS prior to percutaneous RFA. We analyzed our database, radiologic reports, and US images in order to determine whether the location of HCC candidates on planning US coincide with that on CEUS. To avoid incomplete ablation, percutaneous RFA was performed only when HCC nodules were identified on CEUS. The rate of technical success was assessed. The cumulative rate of local tumor progression was estimated with the use of the Kaplan-Meier method (mean follow-up: 24.0 ± 13.0 months). Results Among 82 patients, 73 (89%) HCCs were identified on CEUS, whereas 9 (11%) were not. Of 73 identifiable HCCs on CEUS, the location of HCC on planning US corresponded with that on CEUS in 64 (87.7%), whereas the location did not correspond in 9 (12.3%) HCCs. Technical success was achieved for all 73 identifiable HCCs on CEUS in a single (n = 72) or two (n = 1) RFA sessions. Cumulative rates of local tumor progression were estimated as 1.9% and 15.4% at 1 and 3 years, respectively. Conclusion Pretreatment evaluation with CEUS is effective for percutaneous RFA of HCCs with poor conspicuity on conventional US.

High-throughput fiber-array transvaginal ultrasound/photoacoustic probe for ovarian cancer imaging  

NASA Astrophysics Data System (ADS)

A high-throughput ultrasound/photoacoustic probe for delivering high contrast and signal-to-noise ratio images was designed, constructed, and tested. The probe consists of a transvaginal ultrasound array integrated with four 1mm-core optical fibers and a sheath. The sheath encases transducer and is lined with highly reflecting aluminum for high intensity light output and uniformity while at the same time remaining below the maximum permissible exposure (MPE) recommended by the American National Standards Institute (ANSI). The probe design was optimized by simulating the light fluence distribution in Zemax. The performance of the probe was evaluated by experimental measurements of the fluence and real-time imaging of polyethylene-tubing filled with blood. These results suggest that our probe has great potential for in vivo imaging and characterization of ovarian cancer.

Natural orifice transluminal endoscopic surgery: The transvaginal route moving forward from cholecystectomy  

PubMed Central

The advent of minimally invasive surgery and the advances in endoluminal flexible endoscopy have converged to generate a new concept in digestive surgery, whose acronym natural orifice transluminal endoscopic surgery (NOTES), has become a familiar term in the surgical community. NOTES has been performed through the mouth, the bladder, the rectum and the vagina. Of these four approaches, the vagina has gained most popularity for several reasons. It is not only readily accessible and easy to decontaminate but it also provides safe entry and simple closure. The transvaginal approach has been described in the experimental and the clinical setting as an option for cholecystectomy, nephrectomy, splenectomy, segmental gastrectomy, retroperitoneal exploration and bariatric surgery. However, larger series are needed to delineate the exact risks of this approach, and to transcend cultural barriers that impede its wider introduction. Prospective randomized trials will shed light on the definitive role of the vaginal approach in minimal invasive surgery of the future.

Ultrasonography of the pancreas. 2. Harmonic imaging.  

PubMed

Tissue harmonic imaging (THI) is a relatively new ultrasonographic imaging modality which has been implemented in many modern scanners. As several previous studies have pointed out, THI can help to overcome some shortcomings of conventional B-mode ultrasonography (US). The aim of this article is to give a compact summary of the potentials of THI, focused on pancreatic imaging. Beginning with a recapitulation of the technical background of THI, the particularities and suitable applications of THI in US of the pancreas are discussed. Examination protocols and typical indications are presented together with example images. Finally, new trends and developments in B-mode sonography of the pancreas such as panorama US, compound imaging, and photopic US are mentioned. PMID:16850350

Leg-length discrepancy measured by ultrasonography.  

PubMed

Leg-length discrepancy was determined by real-time ultrasonography (ultrasound) in 45 patients, and the measurements were compared with those of erect-posture radiography. A special device for holding and moving the ultrasound transducer was constructed, and the leg length was measured as the highest level of the femoral head in the standing position. The correlation coefficient r between ultrasound and radiography was 0.94, the mean difference was -1.9 mm, and the limits of agreement (mean +/- 2 SD) were -9.1 to 5.3 mm. The mean difference between examiners 1 and 2 was 1.7 mm, and the 95 percent confidence interval was +/- 7 mm. We conclude that leg-length discrepancy can be reliably determined by ultrasound, although the accuracy is less than that obtained by radiographic methods. Because ultrasound is not limited by radiation hazards, our technique can be used for clinical screening. PMID:2014720

Interventional musculoskeletal ultrasonography: Precautions and contraindications  

PubMed Central

In recent years ultrasonography (US) has emerged as the imaging technique of choice for guiding diagnostic and therapeutic procedures including those related to the musculoskeletal system. However, the absence of ionizing radiation and the elevated safety of the method must not lead us to forget that there are precautions and contraindications to keep in mind, which are crucial to the protection of both the patient and the physician. Among these precautions it is first of all essential to obtain the patient’s accurate clinical history including current medication, particularly if it involves drugs influencing the blood clotting, and information related to possible allergies. The patient should furthermore receive detailed information concerning the procedure (sterile precautions as well as possible side-effects of the drugs which will be injected). In addition to this, there must be a close contact between the radiologist and the patient’s general physician (GP) in order to obtain the best possible result of the procedure.

Diagnosis of pancreatic tumors by endoscopic ultrasonography  

PubMed Central

Pancreatic tumors are highly diverse, as they can be solid or cystic, and benign or malignant. Since their imaging features overlap considerably, it is often difficult to characterize these tumors. In addition, small pancreatic tumors, especially those less than 2 cm in diameter, are difficult to detect and diagnose. For characterizing pancreatic tumors and detecting small pancreatic tumors, endoscopic ultrasonography (EUS) is the most sensitive of the imaging procedures currently available. This technique also provides good results in terms of the preoperative staging of pancreatic tumors. EUS-guided fine needle aspiration (EUS-FNA) has also proved to be a safe and useful method for tissue sampling of pancreatic tumors. Despite these advantages, however, it is still difficult to differentiate between benign and malignant, solid or cystic pancreatic tumors, malignant neoplasms, and chronic pancreatitis using EUS, even when EUS-FNA is performed. Recently, contrast-enhanced EUS with Doppler mode (CE-EUS) employing ultrasound contrast agents, which indicate vascularization in pancreatic lesions, has been found to be useful in the differential diagnosis of pancreatic tumors, especially small pancreatic tumors. However, Doppler ultrasonography with contrast-enhancement has several limitations, including blooming artifacts, poor spatial resolution, and low sensitivity to slow flow. Consequently, an echoendoscope was developed recently that has a broad-band transducer and an imaging mode that was designed specifically for contrast-enhanced harmonic EUS (CEH-EUS) with a second-generation ultrasound contrast agent. The CEH-EUS technique is expected to improve the differential diagnosis of pancreatic disease in the future. This review describes the EUS appearances of common solid and cystic pancreatic masses, the diagnostic accuracy of EUS-FNA, and the relative efficacies and advantages of CE-EUS and CEH-EUS along with their relative advantages and their complementary roles in clinical practice.

The role of B-mode ultrasonography in the detection of urolithiasis in patients with acute renal colic.  

PubMed

This study was conducted to assess the diagnostic yield of B-Mode Ultrasonography compared to unenhanced helical CT scan in detecting urinary stones in patients with acute renal colic. This retrospective study comprised of 156 patients who underwent unenhanced urinary tract CT scan and ultrasonography for suspicion of urolithiasis. Both techniques were used to determine the presence or absence, site, size, and number of urinary stones, as well as presence of any other intra-abdominal pathology. For statistical analysis, the sensitivity, specificity, predictive values, and diagnostic accuracy of ultrasonography were measured considering unenhanced CT scan as a gold standard. Unpaired two-tailed student's t-test was used for comparison between mean size of true positive, false positive, and false negative stones. There were 68 patients having 115 urinary stones. Ultrasound identified 54 stones, missed 43, and falsely diagnosed 18 stones. The mean size of true positive, false positive, and false negative stones were 4.8 +/- 3.3 mm, 6 +/- 1.8 mm and 4.18 +/- 3 mm, respectively. There were 23 patients with other intra-abdominal pathologies, equally detected by both techniques. Ultrasound helped in identifying the cause of acute flank pain in 62% of cases. The overall sensitivity, specificity, positive and negative predictive values, and accuracy of ultrasonography in the diagnosis of renal stone disease were 58%, 91%, 79%, 78%, and 78%, respectively. Our study suggests that, despite its limited value in detecting urinary stones, ultrasonography should be performed as an initial assessment in patients with acute flank pain. Unenhanced helical CT should be reserved for patients in whom ultrasonography is inconclusive. PMID:20427874

Transvaginal Application of a Laparoscopic Bipolar Cutting Forceps to Assist Vaginal Hysterectomy in Extremely Obese Endometrial Cancer Patients  

PubMed Central

Introduction: The purpose of this report is to evaluate our experience with transvaginal application of a laparoscopic bipolar cutting forceps to assist vaginal hysterectomy in extremely obese women with endometrial cancer in whom obesity precluded LAVH/BSO and lymphadenectomy and vaginal obesity limited visualization and exposure. Materials and Methods: We performed a retrospective review and identified 6 consecutive cases. No cases were excluded. A laparoscopic 33-cm Plasma Kinctic (PK) cutting forceps with a 5-mm diameter was applied transvaginally to coagulate and cut the uterosacral and cardinal ligaments, uterine vasculature, and ovarian ligaments. The uterus was delivered vaginally. Staging lymphadenectomy was not performed. Results: Median age was 51 years, median weight was 405 lbs, and median BMI was 66 kg/m2. Five of 6 cases were successfully performed vaginally (83%). Median operative time was 1hour 10 minutes, median blood loss was 500 mL, and pain was only discomforting. All patients were discharged the day after surgery. There were no complications. At median follow-up of 1 year, all patients were alive with no evidence of disease. Conclusions: It is our opinion that the transvaginal application of a laparoscopic bipolar cutting forceps can successfully assist vaginal hysterectomy in extremely obese endometrial cancer patients who cannot tolerate LAVH/BSO and lymphadenectomy and vaginal obesity limits visualization and exposure.

[Muscle ultrasonography: a new diagnostic tool for the diagnosis of ALS].  

PubMed

The diagnosis of amyotrophic lateral sclerosis (ALS) is frequently challenging, and needle EMG plays a central role to assess lower motor neuron dysfunction. Ultrasonography can clearly visualize fasciculation, one of characteristic features of ALS, and could contribute to the diagnosis of ALS. Echogenicity might be useful to assess chronic denervated changes of muscles, although there are some issues to be solved with regard to establishing methods and normal values. Attempts to utilize ultrasound to diagnose ALS have been just started. However, ultrasound has an advantage of non-invasiveness over EMG or nerve conduction study. Ultrasound could become a new tool to evaluate neuromuscular disease without pain in the near future. PMID:24291931

Periportal fibrosis and other liver ultrasonography findings in vinyl chloride workers  

PubMed Central

Aims: To investigate the presence of liver lesions and their relation with vinyl chloride monomer (VCM) exposure or other personal risk factors, in workers involved in the production of VCM and polyvinyl chloride (PVC). Methods: A liver ultrasonography examination was conducted in 757 workers, some of whom had long standing service in the production of VCM and PVC. The study involved: assessment of individual past and present VCM exposure of each worker; collection of past personal health history, lifestyle and personal data; routine liver function tests; and liver ultrasonography. Results: No cases of liver malignancies were detected. Angiomas and liver cysts were found with a frequency of occurrence within the expected range of the general population. The main findings consisted of hepatomegaly (34.7%), steatosis (31.8%), and periportal fibrosis (16.0%). A logistic regression analysis indicated that hepatomegaly and steatosis were associated with obesity and lipid metabolism disturbances and not with VCM exposure. Periportal fibrosis, in addition to constitutional or dietary factors, was shown to be associated with VCM exposure, but only when maximum exposure in the subject's history had been at least 200 ppm as a yearly average; no effects were observed at 50 ppm or below. Conclusions: Workers exposed to 200 ppm VCM for at least one year have a fourfold increased risk of developing periportal liver fibrosis. Liver ultrasonography is a suitable and important diagnostic test for the medical surveillance of vinyl chloride workers.

Co-registered spectral photoacoustic tomography and ultrasonography of breast cancer  

NASA Astrophysics Data System (ADS)

Many breast cancer patients receive neoadjuvant treatment to reduce tumor size and enable breast conserving therapy. Most imaging methods used to monitor response to neoadjuvant chemotherapy or hormone therapy depend on overall gross tumor morphology and size measurements, which may not be sensitive or specific, despite tumor response on a cellular level. A more sensitive and specific method of detecting response to therapy might allow earlier adjustments in treatment, and thus result in better outcomes while avoiding unnecessary morbidity. We developed an imaging system that combines spectral photoacoustic tomography and ultrasonography to predict breast neoadjuvant therapeutic response based on blood volume and blood oxygenation contrast. The system consists of a tunable dye laser pumped by a Nd:YAG laser, a commercial ultrasound imaging system (Philips iU22), and a multichannel data acquisition system which displays co-registered photoacoustic and ultrasound images in real time. Early studies demonstrate functional imaging capabilities, such as oxygen saturation and total concentration of hemoglobin, in addition to ultrasonography of tumor morphology. Further study is needed to determine if the co-registered photoacoustic tomography and ultrasonography system may provide an accurate tool to assess treatment efficacy by monitoring tumor response in vivo.

Usefulness of contrast-enhanced ultrasonography in the diagnosis of renal pseudotumors.  

PubMed

Background: Within the term "pseudotumors" are grouped some renal anatomic variations that may simulate a focal renal lesion at ultrasonography. Our purpose was to assess the accuracy of contrast-enhanced ultrasonography (CEUS) using a second-generation contrast agent in the diagnosis of renal pseudotumors. Methods: We retrospectively retrieved CEUS examinations performed in 24 patients for characterization of suspected renal pseudotumor, in which conventional and power Doppler US study had been unable to confidently exclude a neoplasm. The considered criterion to define the diagnosis of renal pseudotumor was the demonstration of the same perfusion and reperfusion after microbubble breakage in both pseudotumor and surrounding parenchyma during early and late corticomedullary phase. In all patients, multiphase CT or dynamic MRI was available, representing a standard of reference for this study. In cases of CT or MRI diagnosis of renal lesion, final diagnoses were obtained with percutaneous renal biopsy or with surgery. Results: Contrast-enhanced ultrasonography diagnosis was concordant with MR or CT images in all cases. Conclusion: In our experience CEUS shows complete concordance with CT and MRI in the characterization of all 24 pseudotumors considered dubious at conventional and power Doppler US. The appropriate use of CEUS can reduce the need for contrast-enhanced CT or dynamic MRI in this item. PMID:19194642

The role of ultrasonography in primary congenital hypothyroidism  

PubMed Central

BACKGROUND: The aim of this study was to compare the usefulness of ultrasonography and scintigraphy in diagnosing the etiology of primary congenital hypothyroidism (CH). METHODS: The newborns that were examined by both thyroid scintigraphy and ultrasonography during CH screening program in Isfahan were included in this study. The ultrasonographic findings were compared with the scintigraphic findings and the sensitivity and specificity of the ultrasonography was determined. RESULTS: During this study, 102 CH newborns were studied. According to the ultrasonographic results, 61.8%, 26.5%, 2.9% and 8.8% of them had normal thyroid gland, agenesia, ectopia and hypoplasia, respectively, and according to scintigraphic results, 55.9%, 35.3% and 8.8% of them had normal thyroid gland, agenesia and ectopia, respectively. Ultrasound detected sensitivity, specificity, positive predictive value, negative predictive value, and positive and negative likelihood ratio were 77%, 92%, 89%, 84%, 9.6 and 0.25, respectively. The sensitivity and specificity of ultrasonography compared with thyroid scintigraphy in diagnosis of thyroid gland ectopia was 33% and 100%, respectively. CONCLUSIONS: Though thyroid ultrasonography failed to diagnose 67% of ectopic cases and nonfunctioning thyroid gland, it had the ability to determine the anatomy of thyroid gland. So, considering some limitations of scintigraphy, we concluded that ultrasonography is a relatively appropriate imaging tool for diagnosing CH etiologies, especially in the initial phase of CH screening.

Breast ultrasonography: state of the art.  

PubMed

Ultrasonography (US) is an indispensable tool in breast imaging and is complementary to both mammography and magnetic resonance (MR) imaging of the breast. Advances in US technology allow confident characterization of not only benign cysts but also benign and malignant solid masses. Knowledge and understanding of current and emerging US technology, along with the application of meticulous scanning technique, is imperative for image optimization and diagnosis. The ability to synthesize breast US findings with multiple imaging modalities and clinical information is also necessary to ensure the best patient care. US is routinely used to guide breast biopsies and is also emerging as a supplemental screening tool in women with dense breasts and a negative mammogram. This review provides a summary of current state-of-the-art US technology, including elastography, and applications of US in clinical practice as an adjuvant technique to mammography, MR imaging, and the clinical breast examination. The use of breast US for screening, preoperative staging for breast cancer, and breast intervention will also be discussed. PMID:23970509

Intraoperative microvascular Doppler ultrasonography in cerebral aneurysm surgery  

PubMed Central

OBJECTIVES—Outcome of surgical treatment of cerebral aneurysms may be severely compromised by local cerebral ischaemia or infarction resulting from the inadvertent occlusion of an adjacent vessel by the aneurysm clip, or by incomplete aneurysm closure. It is therefore mandatory to optimise clip placement in situ to reduce the complication rate. The present study was performed to investigate the reliability of intraoperative microvascular Doppler ultrasonography (MDU) in cerebral aneurysm surgery, and to assess the impact of this method on the surgical procedure itself.?METHODS—Seventy five patients (19 men, 56 women, mean age 54.8 years, range 22-84 years) with 90 saccular cerebral aneurysms were evaluated. Blood flow velocities in the aneurysmal sac and in the adjacent vessels were determined by MDU before and after aneurysm clipping. The findings of MDU were analysed and compared with those of visual inspection of the surgical site and of postoperative angiography. Analysis was also made of the cases in which the clip was repositioned due to MDU findings.?RESULTS—A relevant stenosis of an adjacent vessel induced by clip positioning that had escaped detection by visual inspection was identified by Doppler ultrasonography in 17 out of 90 (18.9%) aneurysms. In addition, Doppler ultrasound demonstrated a primarily unoccluded aneurysm in 11 out of 90 (12.2%) patients. The aneurysm clip was repositioned on the basis of the MDU findings in 26 out of 90 (28.8%) cases. In middle cerebral artery (MCA) aneurysms, the MDU results were relevant to the surgical procedure in 17out of 44 (38.6%) cases. Whereas with aneurysms of the anterior cerebral artery significant findings occurred in only five of 32cases (15.6%; p<0.05). The clip was repositioned on the basis of the MDU results in 18 out of 50 (36%) aneurysms in patients with subarachnoid haemorrhage (SAH) grade I-V compared with only eight out of 40 (20%) aneurysms in patients without SAH (p<0.05).?CONCLUSIONS—MDU should be used routinely in cerebral aneurysm surgery, especially in cases of MCA aneurysms and after SAH. Present data show that a postoperative angiography becomes superfluous whenever there is good visualisation of the "working site" and MDU findings are clear.??

Ultrasonography of the urinary tract in 29 female Saanen goats.  

PubMed

The left and right kidneys, ureters, urinary bladder and urethra of 29 female clinically healthy Saanen goats were examined via transcutaneous and transrectal ultrasonography. In order to establish reference values the examinations were performed using a 5.0 MHz linear transducer to scan the right caudal costal part of the abdominal wall, right and left dorsal flanks and right and left inguinal regions of standing goats. A 5.0 MHz intracavity probe was used for transrectal ultrasonographic examination of the urinary bladder and urethra. The kidneys were examined in longitudinal and cross section and assessed subjectively. They could usually be seen from the 12th intercostal space on the right side and dorsal right flank. The right kidney was 8.0 ± 0.67 cm long and the left was 8.4 ± 0.64 cm long. The ureters could not be visualized in any of the goats. The length of the urinary bladder was 5.1 ± 1.38 cm, and its largest cross-sectional diameter was 2.6 ± 1.01 cm. The urethra was seen in 23 goats and appeared as echogenic lines with no visible lumen. The transition from the neck of the bladder to the internal urethral orifice extended beyond the brim of the pelvis in only one goat. PMID:22287138

Imaging in juvenile idiopathic arthritis with a focus on ultrasonography.  

PubMed

Early therapeutic intervention and use of new highly efficacious treatments have improved the outcome in many patients with juvenile idiopathic arthritis (JIA), but have also led to the need for more precise methods to evaluate disease activity. In adult rheumatology, numerous studies have established the importance of magnetic resonance imaging (MRI) and ultrasonography (US), and MRI is considered the reference standard. Nevertheless, due to differences in disease characteristics and the unique features of the growing skeleton, the findings obtained in adults are not directly applicable to children and adolescents. For paediatric patients, US offers specific advantages over MRI, because it is non-invasive, does not require sedation or general anesthesia (which facilitates repeated examinations for follow-up), is quickly accessible bedside, and is easy to combine with clinical assessment (interactivity). Agitation of the patient is rarely a problem, and hence young children can be seated on a parent's lap or play while being examined, and multiple locations can be assessed during a single session. Furthermore, modern high-frequency US transducers used by experienced US examiners can provide unsurpassed resolution of the superficial musculoskeletal structures in children. US is also the best available technique for imaging guidance of steroid injections. Unfortunately, there are still no validated MRI or US scoring systems for evaluating inflammatory and joint damage abnormalities in JIA, and few US studies have been conducted. Sonographic assessment of disease activity has, however, been proven to be more informative than clinical examination and is also readily available at points of care. This review summarises the literature on imaging in JIA, focusing on US and the important role this technique will play in JIA in the future. PMID:23294536

Endosonographic Preoperative Evaluation for Tumors of the Ampulla of Vater Using Endoscopic Ultrasonography and Intraductal Ultrasonography  

PubMed Central

Background/Aims In recent years, endoscopic snare papillectomy has been performed to treat tumors of the ampulla of Vater. This procedure requires accurate preoperative evaluation. In this study, we diagnosed the focal extension of such tumors by using endoscopic ultrasonography (EUS) and intraductal ultrasonography (IDUS), and examined the indications for endoscopic snare papillectomy. Methods The subjects were 48 patients with a papillary tumor (13 patients, surgical resection; 35 patients, endoscopic snare papillectomy) who were evaluated preoperatively with EUS and IDUS. The tumor-node-metastasis classification was used for the endosonographic evaluation and pathological diagnosis of these tumors. Results The diagnostic accuracy of EUS was 97% for diagnosing adenomas and pTis tumors, 73% for pT1 tumors, 50% for pT2 tumors, and 50% for pT3-4 tumors, for an overall accuracy of 85% for T-staging. The diagnostic accuracy of IDUS was 94% for adenomas and pTis tumors, 73% for pT1 tumors, 50% for pT2 tumors, and 100% for pT3-4 tumors, for an overall accuracy of 80% for T-staging. Conclusions EUS and IDUS are highly capable of evaluating tumors of the ampulla of Vater preoperatively. However, these techniques are not sufficient for evaluating the focal extension of carcinomas preoperatively. Currently, endoscopic snare papillectomy is adequate for treating adenomas and pTis tumors.

Ultrasonography-guided ethanol ablation of predominantly solid thyroid nodules: a preliminary study for factors that predict the outcome  

PubMed Central

Objectives The aim of this study was to evaluate the success rate in ultrasonography-guided ethanol ablation (EA) of benign, predominantly solid thyroid nodules and to assess the value of colour Doppler ultrasonography in prediction of its success. Methods From January 2008 to June 2009, 30 predominantly solid thyroid nodules in 27 patients were enrolled. Differences in the success rate of EA were assessed according to nodule vascularity, nodule size, ratio of cystic component, amount of injected ethanol, degree of intranodular echo-staining just after ethanol injection and the number of EA sessions. Results On follow-up ultrasonography after EA for treatment of thyroid nodules, 16 nodules showed an excellent response (90% or greater decrease in volume) and 2 nodules showed a good response (50–90% decrease in volume) on follow-up ultrasonography. However, 5 nodules showed an incomplete response (10–50% decrease in volume) and 7 nodules showed a poor response (10% or less decrease in volume). Statistical analysis revealed a significant association of nodule vascularity (p = 0.002) and degree of intranodular echo-staining just after ethanol injection (p = 0.003) with a successful outcome; however, no such association was observed with regard to nodule size, ratio of cystic component, amount of infused ethanol and the number of EA sessions. No serious complications were observed during or after EA. Conclusion The success rate of EA was 60%, and nodule vascularity and intranodular echo-staining on colour Doppler ultrasonography were useful in predicting the success rate of EA for benign, predominantly solid thyroid nodules.

Red flags in bedside ultrasonography for surgical cases  

PubMed Central

Bedside ultrasonography is highly accurate in evaluating hypotension, even if performed by nonradiologist. Here we report three cases presenting with hypotension to the trauma room. In the first case, limited bedside ultrasonography demonstrated dilatation of the inferior vena cava and loss of respiratory variation in diameter. In further evaluation, dilated aortic root, massive pericardial effusion, collapse of right heart chambers, and a dissection flap at the anterior wall of base of ascending aorta were detected. With these findings, the patient was sent to the operation room with a diagnosis of DeBakey type 2 aortic dissection in approximately 15 min. In the second case, bedside ultrasonography demonstrated absence of pleural movements and comet tail artifacts on the right lung region of the patient. Together with deterioration of the vital signs, the patient was diagnosed as right-sided pneumothorax and underwent the tube thoracostomy. In the third case, bedside ultrasonography revealed the presence of free fluid in Morrison’s pouch and splenorenal space in a hypotensive patient with a blunt abdominal trauma. He was consulted with general surgery department and was sent to the operation room without further diagnostic evaluation. In these cases, we emphasized the key role of bedside ultrasonography in hypotensive patients.

Cardiac rhabdomyosarcoma mimicking a mediastinal tumor and the role of endoscopic ultrasonography  

PubMed Central

We report a case of cardiac rhabdomyosarcoma, with initial clinical features of “atrial rhythmic dysfunction”, which was concluded as a mediastinal tumor by computed tomography (CT) scan. Endoscopic ultrasonography (EUS) and EUS-FNA (fine needle aspiration) were initially conducted to diagnose the isolated mediastinal mass. In this case, EUS re-assessed the previous diagnosis as a cardiac tumor, and the patient eventually achieved a 17-month survival rate after chemotherapy. In this paper, EUS findings obtained in our case are described and a review of literatures is briefly discussed. We also describe the advantages and limitations of this technique compared with other image diagnosis alternatives.

Acrania/encephalocele sequence (exencephaly) associated with 92,XXXX karyotype: early prenatal diagnosis at 9(+5) weeks by 3D transvaginal ultrasound and coelocentesis.  

PubMed

A 27-year-old pregnant woman was diagnosed by 3D transvaginal ultrasound as carrying a fetus of 9(+5) weeks gestation affected by acrania/encephalocele (exencephaly) sequence. A 2D transvaginal ultrasound-guided aspiration of 5 mL of extra-coelomic fluid was performed under cervical block before uterine suction. Conventional cytogenetic analysis demonstrated a 92,XXXX karyotype. Transvaginal 2D ultrasound-guided coelocentesis for rapid karyotyping can be proposed to women who are near to miscarriage or in cases where a prenatal ultrasound diagnosis of congenital anomaly is performed at an early stage of development. Genetic analysis can be performed using traditional cytogenetic analysis or can be aided by fluorescence in situ hybridization (FISH). Coelocentesis may become an integral part of first trimester armamentarium and may be clinically useful in the understanding of the pathogenesis of early prenatally diagnosed congenital anomalies.

Management of vesicovaginal fistula: An experience of 52 cases with a rationalized algorithm for choosing the transvaginal or transabdominal approach  

PubMed Central

Purpose: We aim to present our experience for the repair of vesicovaginal fistula (VVF) with special reference to surgical approach. Materials and Methods: From January 1999 to June 2005, 52 VVF patients with mean age of 32 years underwent operative treatment. Fistulas were divided into two groups, simple and complex, depending on site, size, etiology and associated anomalies. Simple VVFs were approached through the vaginal route and complex VVFs via the transabdominal route. Patients were evaluated at two to three weeks initially, three-monthly twice and later depending on symptoms. Results: Thirty-two (61.5%) had simple fistulas and 20 (38.5%) complex fistulas. The most common etiology was obstetric trauma in 31 (59.6%) patients, while the second most common cause was post hysterectomy VVF. Thirty-two (61.5%) patients were managed by transvaginal route, of which 17 had supratrigonal and 15 trigonal fistulas. Twenty (38.5%) patients with complex fistulas were managed by abdominal route. The mean blood loss, postoperative pain and mean hospital stay were shorter in transvaginal repair. Eleven (21.2%) patients required ancillary procedures for various other associated anomalies at the time of fistula repair. Three patients failed repair giving a success rate of 94.2%. At a mean follow-up of three years 48 women were sexually active, of these 10 (19.2%) complained of mild to moderate dyspareunia. Conclusion: Most of the simple fistulas irrespective their locations are easily accessible transvaginally while in complex fistulas we recommend the transabdominal approach. Depending on the clinical context both the approaches achieved comparable success rates.

Importance of the Ultrasonography in Diagnosis of Ileal Duplication Cyst  

PubMed Central

Gastrointestinal duplication cysts are rare congenital anomalies that can be seen in anywhere of the gastrointestinal system from the mouth to the anus. These are prenatally diagnosed through antenatal ultrasonography. However, attention must be paid since these formations might be confused with ovarian or mesenteric cysts. Our patient, who had been diagnosed with ovarian cyst on the ultrasonography performed in another center and with mesenteric cyst based on the abdominal MRI carried out at fifth month of life, presented to our clinic with the only complaint of constipation at 9th month of life. The diagnosis was set through double wall appearance of duplication cyst on the abdominal ultrasonography. The patient's cyst was resected.

Luteal function induced by transvaginal ultrasonic-guided follicular aspiration in mares.  

PubMed

Ultrasonic-guided transvaginal follicle aspiration was performed in 58 crossbreed mares in order to determine whether aspiration of various dominant follicle diameters resulted in luteal tissue capable of producing progesterone (P(4)). The mares were randomly assigned to three groups according to follicular diameter (25-29 mm; 30-35 mm and >35 mm). Mares that had ovulations naturally served as controls. The serum progesterone (P(4)) concentrations in the aspirated mares were greater (P < 0.0001; r(2) = 0.6687; CV = 21.52) in mares with natural ovulation compared to mares with aspirated follicles regardless of groups. Serum P(4) concentration in aspired mares with follicular diameter of 25-29 mm declined 0.365 ng/ml/day (P = 0.0065) from the day of aspiration (D0) up to D8. In mares with follicle diameter of 30-35 mm, serum P(4) concentration increased (0.258 ng/ml/day; P = 0.001), as well as in the mares with follicles >35 mm diameter (0.481 ng/ml/day; P < 0.0001), and in mares with natural ovulation (1.236 ng/ml/day; P < 0.0001). Out of the 25 mares with follicular aspirations that formed Corpora hemorragica (P(4) >1 ng/ml), 23 (92%) had greater (>2 ng/ml) serum P(4) concentrations on Day 8 after aspiration. Of these 23 mares, 75% were in the 25-29 mm group, 9/10 (90%) in the 30-35 mm group, and 11/11 (100%) of the mares in the >35 mm follicular diameter group had luteinization (P(4) >2 ng/ml). These results suggest that a functional Corpus luteum can be induced in mares using follicular aspiration and that a minimum 35 mm follicular diameter is needed to reach a progesterone serum concentration compatible with that of a Corpus luteum produced by natural ovulation.

Prenatal diagnosis of congenital syphilis using two- and three-dimensional ultrasonography: case report.  

PubMed

The numbers of syphilis cases have been increasing considerably, especially in eastern europe, thereby contributing towards greater chances of cases of congenital syphilis. Some of the complications of congenital syphilis can be detected on two-dimensional ultrasonography (2DUS), and these are generally manifested in the second trimester of pregnancy. The commonest ultrasonographic signs are hepatosplenomegaly, placentomegaly, and fetal growth restriction, while lower-frequency occurrences include intrahepatic calcifications, ascites, fetal hydrops, and even fetal death. Three-dimensional ultrasonography (3DUS) is a relatively new imaging technique that is adjuvant to 2DUS and enables detailed assessment of the fetal surface anatomy. We present a case of a 21-year-old primigravida with a diagnosis of congenital syphilis, with obstetric 2DUS findings of hepatosplenomegaly, ascites, pericardial effusion and hyperechogenicity of the cerebral parenchyma. 3DUS in rendering mode allowed clear assessment of the fetal limbs, especially the feet, which appeared twisted and lacked some toes. It allowed the parents to understand the pathological condition better and improved prenatal management and neonatal followup. 3DUS can be used routinely for assessing fetal malformations resulting from congenital infections.

Ultrasonography and computed tomography of inflammatory abdominal wall lesions  

SciTech Connect

Twenty-four patients with inflammatory lesions of the abdominal wall were examined by ultrasonography. Nine of these patients underwent computed tomographic (CT) scanning as well. Both ultrasonography and CT clearly delineated the exact location and extent of abdominal wall abscesses. Abscesses were easily differentiated from cellulitis or phlegmon with ultrasound. The peritoneal line was more clearly delineated on ultrasonograms than on CT scans; abscesses were also more distinct on the ultrasonograms because of their low echogenicity compared with the surrounding structures. Gas bubbles, fat density with specific low attenuation values, and underlying inflamed bowel loops in obese patients with Crohn's disease were better delineated by CT.

Echo intensity obtained from ultrasonography images reflecting muscle strength in elderly men  

PubMed Central

Background It is well known that loss of muscle mass (quantitative change) is a major change that occurs with aging. Qualitative changes in skeletal muscle, such as increased intramuscular fat, also occur as one ages. Enhanced echo intensity (EI) on ultrasonography images of skeletal muscle is believed to reflect muscle quality. Recent studies evaluating the quality of skeletal muscle using computer-aided gray scale analysis showed that EI is associated with muscle strength independently of age or muscle size in middle-aged and elderly women. The aim of the present study was to investigate whether muscle quality based on EI is associated with muscle strength independently of muscle size for elderly men. Methods A total of 184 elderly men (65–91 years) living independently in Kyoto, Japan, participated in this study. The EI, muscle thickness (MT), and subcutaneous fat thickness (FT) of the anterior compartment of the right thigh were determined by assessing ultrasonography images. The maximum isometric torque of knee extension at a knee angle of 90° was measured. Results The EI showed a significant negative correlation with muscle strength (r = ?0.333, P < 0.001). Multivariate regression analysis revealed that the MT and EI of the knee extensor muscle were independently associated with maximum isometric knee extension strength. Even when partial correlation analysis was performed with age, height, weight, and FT as control variables, EI was still significantly correlated with muscle strength. Conclusion The results of this study indicate that aging-related changes in muscle quality contribute to diminishing muscle strength. Ultrasonography is a low-cost, easily accessible, and safe method suitable for the assessment of EI as an index of muscle quality.

The conventional sonographic examinations exhibited solitary lesions without common respects, while contrast-enhanced ultrasonography (CEUS) revealed nodular appearance mimicking its pathologic characteristics. It suggests that CEUS can provide morphologic information for diagnosing SANT.

Laryngeal ultrasonography versus cuff leak test in predicting postextubation stridor.  

PubMed

Introduction: Although cuff leak test has been proposed as a simple method of predicting the occurrence of postextubation stridor, cut-off point of cuff-leak volume substantially differs between previous studies. In addition, laryngeal ultrasonography including measurement of air column width could predict postextubation stridor. The aim of the present study was to evaluate the value of laryngeal ultrasonography versus cuff leak test in predicting postextubation stridor. Methods: In a prospective study, all patients intubated for a minimum of 24 h for acute respiratory failure, airway protection and other causes were included. Patients were evaluated for postextubation stridor and need for reintubation after extubation. The cuff leak volume was defined as a difference between expiratory tidal volumes with the cuff inflated and deflated. Laryngeal air column width was defined as the width of air passed through the vocal cords as determined by laryngeal ultrasonography. The air-column width difference was the width difference between balloon-cuff inflation and deflation. Results: Forty one intubated patients with the mean age of 57.16±20.07 years were included. Postextubation stridor was observed in 4 patients (9.75%). Cuff leak test (cut off point: 249 mL) showed sensitivity and specificity of 75% and 59%, respectively. In addition, laryngeal ultrasonography (cut off point for air column width: 10.95 mm) resulted in sensitivity and specificity of 50% and 54%, respectively. Positive predictive value of both methods were <20%. Conclusion: Both cuff leak test and laryngeal ultrasonography have low positive predictive value and sensitivity in predicting postextubation stridor and should be used with caution in this regard.

Double contrast-enhanced ultrasonography in preoperative Borrmann classification of advanced gastric carcinoma: comparison with histopathology  

PubMed Central

The purpose of this study was to investigate the accuracy of double contrast-enhanced ultrasonography (DCEUS) for assessing the Borrmann classification of advanced gastric carcinoma (AGC) preoperatively. Three hundred twenty nine patients with proved AGC were enrolled. DCEUS (intravenous microbubbles combined with combined with oral contrast-enhanced ultrasound) was performed preoperatively. The diagnostic accuracy of DCEUS in determining Borrmann classification was compared with postoperative pathological findings. The reliability of DCEUS was analyzed. The accuracy of DCEUS in determining the Borrmann classification of AGC was 91.49%. The intra- and inter-observer reproducibility was both almost perfect for assessing the Borrmann classification of AGC by DCEUS. DCEUS could be considered as an accurate, non-invasive, and reliable diagnostic method for preoperative Borrmann classification of advanced gastric carcinoma.

The Current Role of Carotid Duplex Ultrasonography in the Management of Carotid Atherosclerosis: Foundations and Advances  

PubMed Central

The management of atherosclerotic carotid occlusive disease for stroke prevention has entered a time of dramatic change. Improvements in medical management have begun to challenge traditional interventional approaches to asymptomatic carotid stenosis. Simultaneously, carotid artery stenting (CAS) has emerged as an alternative to carotid endarterectomy (CE). Finally, multiple factors beyond degree of stenosis and symptom status now mitigate clinical decision making. These factors include brain perfusion, plaque morphology, and patency of intracranial collaterals (circle of Willis). With all of these changes, it seems prudent to review the role of carotid duplex ultrasonography in the management of atherosclerotic carotid occlusive disease for stroke prevention. Carotid duplex ultrasonography (CDU) for initial and serial imaging of the carotid bifurcation remains an essential component in the management of carotid bifurcation disease. However, correlative axial imaging modalities (computer tomographic angiography (CTA) and contrast-enhanced magnetic resonance angiography (CE-MRA)) increasingly aid in the assessment of individual stroke risk and are important in treatment decisions. The purpose of this paper is twofold: (1) to discuss foundations and advances in CDU and (2) to evaluate the current role of CDU, in light of other imaging modalities, in the clinical management of carotid atherosclerosis.

Endoscopic ultrasonography: Challenges and opportunities in the developing world  

PubMed Central

Endoscopic ultrasonography (EUS) has become a vital diagnostic modality for the evaluation of mediastinal lymphadenopathy, pancreatic cysts and masses, anorectal pathology, subepithelial gastrointestinal lesions, and for the staging of many gastrointestinal and pulmonary malignancies. Establishing a EUS program in a developing country presents many challenges. Doing so in Pakistan has led to the identification of the following challenges: initial investment, ongoing costs (particularly fine needle aspiration needle costs), awareness and cytopathology. Endoscopic ultrasonography has revolutionized aspects of the practice of gastroenterology and oncology in the West. This technique is becoming increasingly available in the developing world, where it poses unique challenges to its practice. These challenges include those relating to service initiation and maintenance costs, physician awareness, and on-site cytopathology access. If these issues are anticipated and addressed in ways appropriate to local circumstances, obstacles to the institution of EUS programs can be overcome.

Musculoskeletal ultrasonography is now widely used by almost all rheumatologists thanks to an improvement in the quality of ultrasound unit and probe and to the systematic teaching of this imaging technique to the rheumatology fellows. Applications have broadened from the study of degenerative and mechanical diseases to inflammatory rheumatic diseases. Ultrasound is more sensitive than clinical examination. Power Doppler allows the direct visualisation of inflammation within the tissues. Finally, it is a prognostic tool helping the physician in the management of the disease. This review will focus on the value and applications of ultrasonography in the 2 most frequent rheumatic diseases: rheumatoid arthritis and spondyloarthritis. We will also give some recent data on the usefulness of this imaging technique in the study of musculoskeletal manifestations associated with connective tissue disease. PMID:24439720

Thyroid gland volume as measured by ultrasonography in preterm infants.  

PubMed

The volume of the thyroid gland was determined by ultrasonography in 30 preterm infants (27-36 weeks' gestation) born in Madrid. Thyroid gland volume significantly increased (p < 0.01) with postnatal and postmenstrual age and was very well correlated with body weight, height and surface area (p < 0.01). Serum thyroid hormones 3,5,3'-triiodothyronine (T3) and free thyroxine (FT4) were linearly correlated with postnatal and postmenstrual age, thus T3 and FT4 levels were also correlated with thyroid gland volume (p < 0.05). We report measurements of the thyroid gland volume obtained by ultrasonography in this group of preterm infants. Quantitative determination of thyroid gland volume is more accurate for the diagnosis of goitre than clinical criteria. It is also interesting to determine the thyroid gland volume in the neonatal period when the thyroid is particularly hypersensitive to the effects of iodine deficiency and excess. PMID:7734900

Diagnostic ultrasonography in cattle with abdominal fat necrosis  

PubMed Central

This study describes the ultrasonographic findings in 14 cows with abdominal fat necrosis. Ultrasonography of the abdomen revealed the presence of heterogeneous hyperechoic masses and hyperechoic omentum with localized masses floating in a hypoechoic peritoneal fluid. A hyperechogenic rim was imaged around both kidneys. The intestines were coated with hyperechoic capsules and the intestinal lumens were constricted. Ultrasonographic examination of the pancreatic parenchyma showed an overall increased echogenicity which was homogenously distributed in 3 cases. A diagnosis of abdominal fat necrosis was made with ultrasound-guided biopsy of the echogenic masses, and thereafter at postmortem examination. Results from this study demonstrate the efficacy of ultrasonography as an imaging modality for antemortem diagnosis of abdominal lipomatosis in cattle. To the authors’ knowledge, this study is the first that illustrates ultrasonographic findings in cattle affected with abdominal lipomatosis.

A New Soft Tissue Volume Measurement Strategy Using Ultrasonography  

PubMed Central

Abstract Various techniques are available for measuring the status of lymphedema. A modified imaging technique using ultrasonography was developed to measure the structure of soft tissue area in a cost-effective manner. The purpose of this study was to measure the reliability and the accuracy of this new method. Ultrasonography was performed on both arms of twenty healthy female participants. At 10?cm above (AE) and below (BE) the elbow crease, soft tissue thickness at medial, lateral, inferior, and superior locations were measured by two examiners with minimal unnecessary pressure. After measuring twice on 16 sites for each participant, the amount of soft tissue in the cross-sectional area (?CSA) was acquired by a designed formulation. The ?CSA was also compared with volumetry data (Perometer®). Cronbach's alpha coefficient test was used for statistics. The intra-class and inter-class reliability measurements for all soft tissue areas were very strong (?=0.980 and 0.960, respectively; p<0.01). All AE and BE reliabilities showed very strong correlation and strong correlation of inter-BE measurement. All reliabilities of ?CSA were very strong (?0.950). All CCs (correlation coefficients) between ?CSA, circumference, and volumetry were strong for AE and BE measurements, except for ?CSA and circumference at BE. The strongest CC was between volumetry and circumference measurements. This study suggests that measuring the ?CSA by ultrasonography could be an alternative way to measure the status of soft tissue indirectly with structural consideration.

Bedside Ultrasonography In Detection Of Post Procedure Pneumothorax  

PubMed Central

Background Bedside ultrasonography in the diagnosis of pneumothorax has been well described in emergency and trauma medicine literature. Its role in detection of iatrogenic pneumothoraces has not been studied. We describe the performance of bedside ultrasonography in detection of procedure related pneumothoraces and highlight some limitations. Methods 185 patients underwent thoracentesis (n=60), transbronchial biopsy (n=48), CT-guided lung biopsy (n=76), and CT-guided cryoablation of a lung mass (n=1). Bedside transthoracic ultrasound examination and post-procedure chest radiograph were performed in all patients. Patients in whom pleural surface was not well imaged with ultrasound were said to have a limited exam. Chest x-ray was the standard for diagnosing pneumothorax. Results Chest x-ray detected pneumothorax in 8/185 patients (4.0%). Ultrasound diagnosed pneumothorax in seven of these patients. Sensitivity, specificity and diagnostic accuracy were 88%, 97% and 97%, respectively. Limited quality ultrasound examinations due to pre-existing lung disease was seen in 43/185 patients. The positive and negative likelihood ratios for patients with adequate scans were 55 and 0.17, respectively. Likelihood ratio for patients with limited quality scan was 1.08. Conclusions Bedside chest ultrasonography, in the presence of good quality scan, is a valuable tool in the evaluation of post procedure pneumothorax. Patients with preexisting lung disease in whom the quality of ultrasound examination is limited should be studied with a chest x-ray.

[Thyroid ultrasonography--considerations and progress in routine diagnostic examinations].  

PubMed

Thyroid ultrasonography is becoming increasingly important because it is easy to perform non-invasively and provides much more information than other imaging devices such as CT and MRI. It is possible to infer the causes of diffuse goiter and thyrotoxicosis by the internal echo level and blood flow analysis. The combination of B mode and color Doppler imaging is also useful for the diagnosis of thyroid nodules. Malignant B mode findings include an irregular shape, indistinct border, hypo and inhomogeneous internal echo, and fine calcification. New diagnostic criteria for thyroid nodules and a flow chart for the selection of indications of aspiration biopsy cytology have been developed by the Japan Association of Breast and Thyroid Sonology. Recent improvements in thyroid ultrasonography include 3D imaging, contrast agents and tissue elasticity imaging. 3D ultrasonography and contrast agents have made it possible to display vascular structures more accurately. Tissue elasticity imaging is expected to play an important role in the diagnosis of thyroid carcinomas since it evaluates tissue stiffness objectively. Tissue elastography may be useful for the differentiation of follicular adenomas from follicular carcinomas, which is still one of the most difficult clinical challenges for all endocrinologists. It also provides detailed information on the efficacy of thyroid interventions. New combinations with tissue elastography and other imaging devices are under development. PMID:24724429

Development of a numerical index quantitating small bowel damage as detected by ultrasonography in Crohn's disease.  

PubMed

Small intestine contrast ultrasonography (SICUS) has emerged as a valuable tool in the detection of intestinal damage in Crohn's disease (CD). Our aim was to develop a numerical index quantitating small bowel damage as detected by SICUS in patients with an established diagnosis of CD. One hundred and ten patients with ileal or ileocolonic CD were prospectively enrolled and followed up for one year. Disease activity was assessed by CDAI and CRP levels. Study variables included bowel wall thickness, lumen diameter, lesion length and number of lesion site. Fistula, mesenteric adipose tissue alteration, abscess and lymphnodes were also considered. Bowel segments were considered as a hollow cylinder. Standardized variations of variables were combined into a statistical and mathematical model to create an algorithm scoring an index value ranging from 0 to 200. Index was subdivided into a severity scale with 5 classes from the lower (A) to the higher score (E). Median lesion index value was significantly higher (p<0.005) in patients with a CDAI>150 and in patients with CRP>5 mg/l (p=0.003). Patients classified in class E and D at SICUS underwent surgery within one year follow up more frequently than those in class C, B and A (p<0.0001). We propose a new index for assessment of small bowel lesions in CD (SLIC: sonographic lesion index for CD) developed by using SICUS. This index may turn ultrasonography in CD from a descriptive qualitative assessment to a quantitative numerical index suitable for comparison studies. PMID:22398077

Description of the use of contrast-enhanced ultrasonography in four dogs with pancreatic tumours.  

PubMed

Canine pancreatic tumours are rare compared to human medicine and the detection and differentiation of pancreatic neoplasia is challenging with B-mode ultrasonography, which often leads to late clinical diagnosis and poor prognosis. This case report describes the findings of contrast-enhanced ultrasonography in four dogs with pancreatic adenocarcinoma or insulinoma. B-mode ultrasonography of the pancreas revealed a hypoechoic nodule in three dogs and heterogenous tissue in one dog. Contrast-enhanced ultrasonography was able to differentiate between two tumour types: adenocarcinomas showed hypoechoic and hypovascular lesions, whereas insulinomas showed uniformly hypervascular lesions. Contrast-enhanced ultrasonography findings were confirmed by cytology and/or histopathology. The results demonstrated that contrast-enhanced ultrasonography was able to establish different enhancement patterns between exocrine (adenocarcinoma) and endocrine (insulinoma) tumours in dogs.

Ultrasonography for diagnosis of slipped capital femoral epiphysis. Comparison with radiography in 9 cases.  

PubMed

In 7 of 8 patients with non-acute slipped capital femoral epiphysis, the slip was visualized by ultrasound. The mean epiphyseal displacement was 6.0 mm, measured on an anterior ultrasound scan. Grading of slip severity by ultrasound was consistent with the radiographic assessment. Two patients had a moderate hip joint effusion which did not affect the final outcome, whereas one patient with an acute slip had a pronounced effusion, and necrosis of the epiphysis occurred. The anteversion angles of the affected hips were reduced as compared to those of the normal hips. It was concluded that ultrasonography was reliable in detecting pronounced and mild degrees of epiphyseal slips, whereas minimal slips could be missed. The detection of hip effusion is important because a tamponade may cause vascular impairment of the epiphysis, unless aspirated. PMID:1471516

Staging and follow-up of primary gastric lymphoma by endoscopic ultrasonography.  

PubMed

The usefulness of endoscopic ultrasonography (EUS) was assessed for diagnosing the depth of invasion in the gastric wall, the infiltration to the adjacent organs, and detecting regional lymph node involvement in primary gastric lymphoma. EUS was performed in 11 patients with primary gastric lymphoma who subsequently underwent gastrectomy with lymph node dissection, as well as chemotherapy in some cases. EUS findings showed a good correlation with the histopathology of the resected specimens. An accurate diagnosis of the depth of invasion into the gastric wall was made in 10 of 11 patients using the same T grade of the 1987 TNM system for gastric carcinoma. EUS also clearly visualized the reduction of depth of tumor invasion in two patients who underwent chemotherapy. Perigastric lymph node involvement could be detected accurately in nine of 11 patients. In conclusion, EUS is an excellent and sensitive diagnostic modality for the preoperative staging and follow-up of primary gastric lymphoma. PMID:2038994

Ultrasonography in the evaluation of midpalatal suture in surgically assisted rapid maxillary expansion.  

PubMed

Surgically assisted rapid maxillary expansion (SARME), which combines orthodontics and surgery, is a well-established therapy for transverse maxillary hypoplasia in adults after sutural closure or completion of skeletal maturation. X-rays are usually the preferred monitoring technique for this treatment. Recently, ultrasound scanning has been used successfully in the follow-up of patients undergoing distraction osteogenesis. In this study, ultrasonography (US) was used in the evaluation of bone callus formation in the midpalatal suture in 3 patients undergoing SARME. For each patient, US was performed immediately after active expansion, at 2 and 4 months of the expansion period, at the removal of the expander 6 months later, and at 2 months after expander removal. The results indicated that US might be a useful and accurate method to assess bone fill in the midpalatal suture in patients undergoing SARME. However, further studies are necessary to clarify the US scores in a larger patient group undergoing SARME. PMID:22948650

Endorectal ultrasonography and treatment of early stage rectal cancer.  

PubMed

The purpose of this study was to evaluate the accuracy of preoperative staging by endorectal ultrasonography (EUS) and its contribution to treatment of early stage rectal cancer (ESRC). The results of EUS for 154 consecutive patients with ESRC (pTis to pT2) were compared prospectively with histologic findings, assessed according to the TNM classification. Results of treatment selection and long-term outcomes were analyzed retrospectively. There were 35 patients histologically staged as pTis, 8 as pT1-slight (invasion confined to the superficial one-third of the submucosa), 37 as pT1-massive (invasion extending to the deeper submucosa), and 74 as pT2. The equipment used was an echoendoscope GF-UM2 or GF-UM3 (Olympus, Tokyo, Japan). Sensitivity/specificity/overall accuracy rates for detection of slight submucosal invasion, massive submucosal invasion, and muscularis propria invasion were 99%/74%/96%, 98%/88%/97%, and 97%/93%/96%, respectively. Incidences of lymph node metastasis in pTis, pTis to pT1-slight, pT1, pT1-massive, and pT2 cases were 0%, 0%, 18%, 22%, and 30%, respectively. Incidences of lymph node metastasis in ESRCs staged by EUS (u) as uTis, uT1-slight, uT1-massive, uT2, and uT3 by EUS were 0%, 0%, 26%, 36%, and 64%, respectively. Sensitivity, specificity, and overall accuracy rates for detection of positive nodes in overall ESRCs were 53%, 77%, and 72%, respectively. Of the 43 patients with pTis to pT1-slight tumors, 22 underwent endoscopic polypectomy or local excision, 20 radical surgery, and 1 radical surgery after endoscopic polypectomy due to vascular invasion. All these patients are alive and all but one (who refused radical surgery due to vascular invasion after local excision and developed liver and lung metastases) are disease-free. Of the 37 patients with pT1-massive tumors, 34 underwent radical surgery and 3 transcoccygeal segmental resection. All these patients are alive disease-free except for one who died of peritoneal carcinomatosis after radical surgery. All patients with pT2 tumors underwent radical surgery. The overall 5-year survival rates for pTis, pT1, and pT2 cases were 100%, 98%, and 97%, respectively. EUS is an accurate method for evaluating invasion depth in ESRC. Patients with uTis or uT1-slight tumors staged by EUS are at low risk of positive nodes and good candidates for endoscopic polypectomy or local excision. Those with uT1-massive or uT2 lesions should be treated with a radical operation because of the high incidence of positive nodes. PMID:11036283

Ultrasonography of the reticulum in 30 healthy Saanen goats  

PubMed Central

Background The reticulum plays a crucial role in the ruminant digestive tract because the primary cycle of rumen motility always starts with a reticular contraction. In contrast to cattle, there are only few results on the ultrasonographic examination of the reticulum in goats. Therefore, it was the goal of the present study, to describe the results of ultrasonography of the reticulum of 30 healthy Saanen goats. Methods Ultrasonography was carried out on standing, non-sedated animals using a 5.0 MHz linear transducer. The shape, contour and motility of the reticulum were investigated. A nine-minute video recording of the reticulum was made for each goat and the frequency, duration and amplitude of reticular contractions were calculated as described for cattle. Results The reticulum appeared as a crescent-shaped structure with a smooth contour located immediately adjacent to the diaphragm. 0.8 to 2.1 (1.41 ± 0.31) reticular contractions were seen per minute. In all goats, biphasic reticular contractions were observed. 90% of the goats also had monophasic reticular contractions, and two had triphasic contractions. During the nine-minute observation periods, there were 0 to 6 monophasic reticular contractions and 6 to 15 biphasic contractions per goat. The duration of the biphasic contractions was 6.56 ± 0.74 s, which was significantly longer than the monophasic contractions at 4.31 ± 0.81 s. The average interval between two reticular contractions was 45.06 ± 12.57 s. Conclusion Ultrasonography of the reticulum in goats is a valuable tool to characterise the appearance and motility of this organ. In addition to the biphasic motility pattern seen in cattle the reticular motility of goats is characterized by monophasic reticular contractions. The results of the present study are an important contribution for better understanding of the reticular motility in goats.

Vaginal sonographic hydrotubation was assessed in the evaluation of uterine configuration and tubal patency. In addition, technique using "agitated" saline during transvaginal sonography was evaluated. Ultrasound was more effective in detecting abnormalities of both interstitial and distal parts of the tube compared with hysterosalpingography. Sonohysterosalpingography is cheaper, may be performed in the office and also the pelvic irradiation is avoided. PMID:14756031

Abdominal ultrasonography in HIV/AIDS patients in southwestern Nigeria  

PubMed Central

Background Though the major target of the HIV-virus is the immune system, the frequency of abdominal disorders in HIV/AIDS patients has been reported to be second only to pulmonary disease. These abdominal manifestations may be on the increase as the use of antiretroviral therapy has increased life expectancy and improved quality of life. Ultrasonography is an easy to perform, non invasive, inexpensive and safe imaging technique that is invaluable in Africa where AIDS is most prevalent and where sophisticated diagnostic tools are not readily available. Purpose: To describe the findings and evaluate the clinical utility of abdominal ultrasonography in HIV/AIDS patients in Ibadan, Nigeria Methods A Prospective evaluation of the abdominal ultrasonography of 391 HIV-positive patients as well as 391 age and sex-matched HIV-negative patients were carried out at the University College Hospital, Ibadan. Results Of the 391 cases studied, 260 (66.5%) were females; the mean age was 38.02 years, (range 15–66 years). The disease was most prevalent in the 4th decade with an incidence of 40.4%. Compared with the HIV-negative individuals, the HIV+ group of patients had a significantly higher proportion of splenomegaly (13.5% vs. 7.7%; p < 0.01), lymphadenopathy (2.0% vs. 1.3%; p < 0.70), and renal abnormalities (8.4% vs. 3.8%; p < 0.02). There were no differences in hepatic and pancreatic abnormalities between the HIV+ and HIV- groups. There were significantly fewer gallstones in the HIV+ group (1.4% vs. 5.1%; p < 0.01). Conclusion AIDS is a multi-systemic disease and its demographic and clinical pattern remains the same globally. Ultrasonography is optimally suited for its clinical management especially in Africa. Its accuracy and sensitivity may be much improved with clinico-pathologic correlation which may not be readily available in developing countries; further studies may provide this much needed diagnostic algorithms.

Contrast-Enhanced Harmonic Endoscopic Ultrasonography in Pancreatic Diseases  

PubMed Central

Endoscopic ultrasonography (EUS) is the most sensitive imaging method for diagnosis of pancreatic tumors. However, it still has limits in the differentiation between pancreatic cancers and inflammatory tumor-like masses. A novel technology, contrast-enhanced harmonic EUS (CH-EUS), has been developed recently. It can visualize both parenchymal perfusion and microvasculature in pancreas without Doppler-related artifacts. Therefore, it is superior to EUS and CT in detecting small pancreatic masses and differential diagnosis of pancreatic masses. CH-EUS could be used for adequate sampling of pancreatic tumors and may predict the pathological features of the pancreatic solid lesions but still cannot replace EUS-FNA now.

Review of the results of the application of an advanced signal-processing technique, called time delay spectrometry, in obtaining soft tissue transmission images by transmission ultrasonography, both in vivo and in vitro. The presented results include amplitude ultrasound pictures and phase ultrasound pictures obtained by this technique. While amplitude ultrasonographs of tissue are closely analogous to X-ray pictures in that differential absorption is imaged, phase ultrasonographs represent an entirely new source of information based on differential time of propagation. Thus, a new source of information is made available for detailed analysis.

Ultrasonography reveals nail thickening in patients with chronic plaque psoriasis.  

PubMed

Nail psoriasis is usually investigated and diagnosed by clinical examination. Ultrasonography is a non-invasive imaging technique for studying soft tissue involvement. The objective of this study was to estimate nail involvement in patients with chronic plaque psoriasis by ultrasonography. Prevalence, clinical type and severity of nail involvement according to nail psoriasis and severity index (NAPSI) were investigated in 138 patients with psoriasis. The thickness of the plate and bed of the fingernails was measured in 54 patients with psoriasis, 46 healthy controls and 37 patients with chronic eczema, using an ultrasonographic system equipped with a frequency transducer of 18 MHz. The prevalence of nail psoriasis was 73 % (102 out of 138). Onycholysis and thickening of the nail plate were the most common clinical type affecting 56 and 50 % of patients, respectively; splinter haemorrhages was the less common involving 10 % of patients. The mean NAPSI score was 18.4 ± 17.5 (SD; range 0-107). The thickness of fingernail plate and bed was significantly higher in patients with psoriasis with nail disease compared to healthy controls and patients with chronic eczema (p < 0.001). There was a linear correlation between NAPSI and plate and bed nail thickness (r = 0.52 and r = 0.38, p = 0.001). Increased nail plate and bed thickness was observed also in patients with psoriasis without clinically apparent nail involvement. In conclusion, thickening of the nail is a common feature of nail psoriasis also in patients without clinically apparent nail involvement. PMID:23011659

Increased wall thickness using ultrasonography is associated with inflammation in an animal model of experimental colitis  

PubMed Central

Experimentally induced colitis is used in animals to investigate pathophysiological mechanisms in inflammatory bowel disease. When following disease course and treatment effects, it should be possible to perform repeated measurements without harming the animals. This pilot study was performed to investigate whether transabdominal ultrasound using a clinical scanner could be used on rats to demonstrate bowel inflammation in an experimental colitis model. Colitis was induced by either 5% dextran sodium sulfate (DSS) in drinking water for 7 days or a single dose of intracolonic trinitrobenzene sulfonic acid (TNBS). Using ultrasonography, wall thickness of distal colon, cecum, and small bowel was recorded prior to and after DSS, and prior to, 2, and 7 days after TNBS. Blood (tumor necrosis factor [TNF]-alpha) and fecal samples (HemoFEC occult blood) were taken from each group on the same days as sonography. Thereafter, rats were killed and specimens for histology were taken. Wall thickness of distal colon, not of cecum or small bowel, increased significantly after 7 days of DSS, and wall thickness of both distal colon and small bowel increased on day 2 and 7 after TNBS. TNF-alpha increased after 7 days in the latter group only. There was a significant correlation between ultrasonographic measurements and combined histology score of distal colon in the DSS group. HemoFEC was also positive in accordance with sonographic and histological features. Increased intestinal wall thickness in response to both DSS- and TNBS-induced colitis was able to be visualized by transabdominal sonography. Moreover, ultrasound findings, occult blood sampling, and histological findings supported each other, indicating that ultrasonography can be used to assess inflammation in a rat experimental model.

Evaluation of abdominal ultrasonography mass screening for hepatocellular carcinoma in Taiwan.  

PubMed

Mass screening with abdominal ultrasonography (AUS) has been suggested as a tool to control adult hepatocellular carcinoma (HCC) in individuals, but its efficacy in reducing HCC mortality has never been demonstrated. This study aimed to assess the effectiveness of reducing HCC mortality by mass AUS screening for HCC based on a program designed and implemented in the Changhua Community-based Integrated Screening (CHCIS) program with an efficient invitation scheme guided by the risk score. We invited 11,114 (27.0%) of 41,219 eligible Taiwanese subjects between 45 and 69 years of age who resided in an HCC high-incidence area to attend a risk score-guided mass AUS screening between 2008 and 2010. The efficacy of reducing HCC mortality was estimated. Of the 8,962 AUS screening attendees (with an 80.6% attendance rate), a total of 16 confirmed HCC cases were identified through community-based ultrasonography screening. Among the 16 screen-detected HCC cases, only two died from HCC, indicating a favorable survival. The cumulative mortality due to HCC (per 100,000) was considerably lower in the invited AUS group (17.26) compared with the uninvited AUS group (42.87) and the historical control group (47.51), yielding age- and gender-adjusted relative mortality rates of 0.69 (95% confidence interval [CI]: 0.56-0.84) and 0.63 (95% CI: 0.52-0.77), respectively. Conclusion: The residents invited to community-based AUS screening for HCC, compared with those who were not invited, showed a reduction in HCC mortality by ?31% among subjects aged 45-69 years who had not been included in the nationwide vaccination program against hepatitis B virus infection.

Transvaginal ovarian trauma, poor responders and improvement of success rates in IVF: Anecdotal data and a hypothesis.  

PubMed

In this report, we propose an intervention capable of improving IVF outcomes in subfertile women with poor ovarian response. This intervention derives from anecdotal data and observations in our daily practice, but most importantly from trials on experimental models and subfertile women with Polycystic Ovarian Syndrome (PCOS). Our hypothesis suggests that transvaginal induction of trauma to the ovary in the cycle preceding IVF should benefit poor ovarian responders and their lowered pregnancy rates by increasing - at least - the number of retrieved oocytes during oocyte retrieval. Up-to-the minute data show that, via this means, there is a unique response of the ovarian surface epithelium and stroma to the induced trauma. The potential pathways of this beneficial response involve an improvement of the raised gonadotrophins to act either through the mechanical reduction of the size of the ovary or through alterations of the hormonal profile by lowering LH, inhibin and local androgen concentrations through hypothalamic-pituitary axis feedbacks, the induction of increased blood flow to the ovaries, a differentiated local immune reaction and a non-elucidated as yet role of reactive oxygen species. In this report, we also describe the technique and the associated possible negative points while we try to point out the needed research steps to ensure its efficiency before it enters daily clinical practice.

Transperineal ultrasonography for evaluation of the perianal fistula and abscess in pediatric Crohn disease: preliminary study  

PubMed Central

Purpose: To assess the feasibility and effectiveness of transperineal ultrasonography (TPUS) for the evaluation of perianal Crohn disease (PCD) in pediatric patients. Methods: Between September 2010 and August 2013, 64 TPUS examinations were performed in 43 patients (34 males and 9 females; mean age±standard deviation, 13.3±2.4 years; age range, 6 to 17 years) to evaluate PCD. The pain severity, location, and activity of perianal fistula, the presence of an abscess, and anal canal hyperemia were retrospectively evaluated. Spearman rank correlation analysis was performed to assess the relationship between the severity of the pain and the fistula activity, the presence of an abscess, and anal canal hyperemia. Results: All examinations were successfully performed. Thirty-nine examinations (60.9%) were performed without any pain experienced by the patient, 19 examinations (29.7%) with mild pain, five examinations (7.8%) with moderate pain, and one examination (1.6%) with severe pain. The pain severity was correlated with the fistula activity (P<0.01). An anterior fistula location was more common than a posterior location. Active fistulas and abscesses were identified during 30 examinations (46.9%) and 12 examinations (18.8%), respectively. Anal canal hyperemia was identified in 31 examinations (48.4%). Conclusion: TPUS with a color Doppler study is useful for visualizing a perianal fistula or abscess and for assessing its inflammatory activity in pediatric Crohn patients.

Ultrasonography in the diagnosis and management of patients with inflammatory arthritides.  

PubMed

In primary care and internal medicine settings clinicians are often reluctant to take advantage of the resources that ultrasonography (US) offers as a diagnostic tool in the initial management of patients with inflammatory arthritis, despite the recognised importance of an accurate and timely diagnosis of rheumatoid arthritis (RA) and of early referral to ensure optimal patient management. Both grey-scale (GS) and power Doppler (PD) imaging have been extensively used in early detection of synovitis and bone erosions in patients with inflammatory arthritides. We reviewed the main data on the clinical use of US in the initial management of patients with inflammatory arthritis, focusing on RA diagnosis in patients with undifferentiated arthritis, prediction of disease severity, differential diagnoses and assessment of synovitis in children with juvenile idiopathic arthritis (JIA). The role of US in assessing treatment response and monitoring disease activity in clinical remission was also briefly evaluated. The reliability of US as a diagnostic tool in rheumatological diseases has greatly advanced in the last years and the use of this imaging technique, in association with conventional assessments such as physical examination and serological tests, should be considered more often also in primary care settings.

[Evaluation of preoperative effect for rectal cancer by transrectal ultrasonography].  

PubMed

The ultrasonographic examination was applied for the purpose of volume estimation of rectal cancer. We have performed 15 cases of echographic volume estimation compared with that of resected specimen (control group) and mean volume estimation error rate was 14.6% between two methods. And we also performed 17 preoperative irradiation cases of rectal cancer. Each tumor volume of pre- and post-irradiation was estimated echogenically and was compared with that of resected specimen. In the case when irradiation effect was remarkable, estimated volume by ultrasonography was much smaller in post-irradiation compared with that of pre-irradiation. Same tendency was also recognized in the study of resected specimen. Histopathological irradiation effect was also highly recognized in the case when echographic diminished rate was prominent. This method will useful for the judgement of preoperative irradiation effect in rectal cancer. PMID:2038288

Ultrasonography and radiography of the hip in infants.  

PubMed

Both hip joints in 156 children, aged 2 months to 2 years, were examined by ultrasonography (ultrasound) and radiography. Pathologic findings were based on an increased acetabular index, bony defects of the lateral acetabular rim, and lateral and/or proximal displacement of the proximal femur. Each hip was classified as normal, dysplasia, subluxation, or dislocation. The same diagnosis was reached by ultrasound and radiography in 303 of the 312 hips. The accordance was good in normal joints, in subluxation, and in dislocation. However in 7 of the 15 hips with radiographic dysplasia, ultrasound was normal. These patients were not treated, and spontaneous normalization or improvement occurred in all of them. One parameter only, the distance from the lateral margin of the ossification center of the femoral head to Perkins' line, was measured by both ultrasound and radiography; the correlation was high (r = 0.73). We recommend ultrasound as the primary imaging technique when congenital dislocation is suspected clinically. PMID:2696321

Interventional ultrasonography of the chest: Techniques and indications  

PubMed Central

Thoracic ultrasonography can be used for diagnostic purposes as well as a guide for diagnostic and therapeutic interventions. When the lesion or fluid collection has been located and the patient properly positioned, the angle of the needle is identified with respect to the transducer. The insertion tract should transgress the smallest possible area of aerated parenchyma. The needle can be introduced with a free-hand technique or with the aid of a needle guide. Correct planning of the procedure reduces intervention time and decreases the risk of complications. The main indications are superficial masses that require biopsy, pleural and parenchymal lesions formerly biopsied with CT or fluoroscopic guidance, and fluid collections that need to be drained. Ultrasound, thanks to its widespread use, simple execution, and low costs, represents a safe, manageable guide for thoracic interventions.

Intraoperative contrast-enhanced ultrasonography of normal canine jejunum.  

PubMed

Nine normal juvenile dogs were evaluated with direct jejunal contrast-enhanced ultrasonography via midline celiotomy. Three different doses of ultrasound contrast medium (Definity®) were injected through a peripheral venous catheter. Time-intensity curves were used to calculate baseline, time to initial rise, inflow slope, time-to-peak, peak intensity (PI), and outflow slope for each administered dose. PI was directly proportional to dose. Outflow slope was similar for all patients, independent of dose. The most favorable images were acquired with a dose of 0.030 ml/kg given as a rapid intravenous manual bolus. The technique and normal jejunal perfusion pattern described herein may provide useful data for evaluation of intestinal vascular, inflammatory, and neoplastic disease in the dog. PMID:21388474

Prenatal diagnosis of limb abnormalities: role of fetal ultrasonography  

PubMed Central

Fetal ultrasonografy is the most important tool to provide prenatal diagnosis of fetal anomalies. The detection of limb abnormalities may be a complex problem if the correct diagnostic approch is not established. A careful description of the abnormality using the rigth nomenclature is the first step. Looking for other associated abnormalities is the threshold to suspect chromosomal abnormalities or single gene disorder. According to the patogenic point of view, limb abnormalities may be the result of malformation, deformation, or disruption. The prenatal diagnosis and the management of limb abnormalities involve a multidisciplinary team of ostetrician, radiologist/sonologist, clinical geneticist, neonatologist, and orthopedic surgeons to provide the parents with the information regarding etiology of the disorder, prognosis, option related to the pregnancy and recurrence risk for future pregnancies. The aim of this review is to describe the importance of detailed fetal ultrasonography in prenatal diagnosis of limb abnormalities.

Imaging of a Renal Artery Aneurysm Detected Incidentally on Ultrasonography  

PubMed Central

Renal artery aneurysms occur with a frequency of less than 1% of the general population. Even if they are usually asymptomatic and incidentally found, they can be complicated with life-threatening conditions like rupture, thrombosis, embolism, or hypertension. Thus, once diagnosed, they should be fully evaluated with further imaging and treated when indicated. We present the case of a patient who was referred for ultrasonography for an unrelated reason. The examination demonstrated a hyperechoic focus near the right kidney. Further imaging workup with MDCT established the diagnosis of a right renal artery aneurysm which was saccular in shape and peripherally calcified. This ring-like calcification was also visible in a KUB radiography which was also performed. After presenting the case, various aspects of this rare entity are discussed.

Usefulness of ultrasound elastography in reducing the number of Breast Imaging Reporting and Data System category 3 lesions on ultrasonography  

PubMed Central

Purpose: To evaluate the negative predictive value (NPV) of ultrasound (US) elastography for non-palpable Breast Imaging Reporting and Data System (BI-RADS) category 3 lesions on ultrasonography and to determine whether US elastography is helpful in reducing the number of BI-RADS category 3 lesions on ultrasonography. Methods: Two hundred seventy-six consecutive, non-palpable BI-RADS category 3 lesions in 256 women who underwent US elastography and US-guided core biopsy, and who had at least 12 months of follow-up data, comprised our study group. The BI-RADS final assessment category and elasticity score were prospectively and independently classified. The rate of malignancy and NPV according to the elasticity score were analysed. We also investigated whether there was a subset of BI-RADS category 3 lesions that were of benign histology but negative on elastography. Results: Of the 276 non-palpable BI-RADS category 3 lesions, three lesions (1.0%) were finally confirmed as ductal carcinomas in situ. No cancers were found in the remaining 273 lesions with benign biopsy histology at a mean follow-up of 39.4 months (range, 12 to 72 months). The NPV of a negative elasticity score (elasticity score of 1) was 99.3% (165 of 166). If BI-RADS category 3 lesions showing a negative elasticity score were downgraded to BI-RADS category 2, 60.4% (165 of 273) of them with benign histology could have been safely followed without biopsy with an increased malignancy rate from 1% (3 of 276) to 1.8% (2 of 110), which is not significantly higher (P=0.626). Conclusion: US elastography has the potential to reduce the number of BI-RADS category 3 lesions on ultrasonography.

Miniprobe Endoscopic Ultrasonography Has Limitations in Determining the T Stage in Early Colorectal Cancer  

PubMed Central

Background/Aims Mini-probe endoscopic ultrasonography (mEUS) is a useful diagnostic tool for accurate assessment of tumor invasion. The aim of this study was to estimate the accuracy of mEUS in patients with early colorectal cancer (ECC). Methods Ninety lesions of ECC underwent mEUS for pre-treatment staging. We divided the lesions into either the mucosal group or the submucosal group according to the mEUS findings. The histological results of the specimens were compared with the mEUS findings. Results The overall accuracy for assessing the depth of tumor invasion (T stage) was 84.4% (76/90). The accuracy of mEUS was significantly lower for submucosal lesions compared to mucosal lesions (p=0.003) and it was lower for large tumors (?2 cm) (p=0.034). The odds ratios of large tumors and submucosal tumors affecting the accuracy of T staging were 3.46 (95% confidence interval [CI], 1.05 to 11.39) and 6.25 (95% CI, 1.85 to 25.14), respectively. When submucosal tumors were combined with large size, the odds ratio was 14.67 (95% CI, 1.46 to 146.96). Conclusions The overall accuracy of T stage determination with mEUS was considerably high in patients with ECC; however, the accuracy decreased when tumor size was >2 cm or the tumor had invaded the submucosal layer.

Mid-term results of pelvic organ prolapse repair using a transvaginal mesh: the experience in Sherbooke, Quebec  

PubMed Central

Objective: The objective was to report our experience on the implantation of the Prolift system since 2005. Methods: Fifty-six patients were operated on between July 2005 and August 2008 by 1 surgeon. The patients were implanted with the transvaginal mesh, the Prolift system, for the treatment of recurrent or high-grade (Baden-Walker stage III or IV) multiple compartment pelvic organ prolapse (POP) associated with symptoms. A concomitant anti-incontinence surgery was performed in 38 patients (68%). Results: The population had a mean age of 68 (range 46–88), a body mass index of 27 (range 21–40) and a parity average of 3 (range 1–16). Previous POP repair had been performed in 17 patients (30%) and a hysterectomy in 43 (77%). The operating room time was on average 98 minutes (range 70–135), blood loss 81 mL (range 50–300) and hospital stay 3 days (range 1–10). With a median follow-up of 21 months, we found that the cure rate for POP was 91% (48/53) and the reoperation rate was 8% (4/53). Perioperative complications included 1 rectal laceration and 1 prolonged bleeding. Short-term postoperative complications included 10 episodes of transient urinary retention that required immediate tape release in 4 patients. Long-term complications included 5 POP recurrences, 2 low grade and 3 high grade. Conclusion: The Prolift system appears to be a relatively safe and effective alternative to conventional surgeries for the treatment of recurrent or high-grade multiple compartment POP, because of a high mid-term cure rate and a satisfactory complication profile. However, long-term follow-up is still needed to confirm these results.

Ultrasonography, 99mTc-DIDA cholescintigraphy, and infusion tomography in the diagnosis of acute cholecystitis.  

PubMed

Ultrasonography, 99mTc-DIDA cholescintigraphy, and infusion tomography of the gallbladder were compared in a prospective study comprising 45 consecutive patients clinically suspected of having acute cholecystitis. The diagnosis of acute cholecystitis was established or excluded by operation in 35 patients, by oral cholecystography in 5, and by intravenous cholangiography in 5. The predictive values of a positive and a negative test were 100% and 83%, respectively, by ultrasonography and 98% and 88% by cholescintigraphy. Corresponding values for infusion tomography were 87% and 33%. The results suggest that in patients suspected of having acute cholecystitis, 99mTc-DIDA cholescintigraphy and ultrasonography provide a rapid and reliable diagnosis. PMID:7134840

Ultrasonography may be very useful for the positive and differential diagnosis of inflammatory rheumatic disorders (rheumatoid arthritis [RA], polymyalgia rheumatica [PMR] and spondylarthropathies) and if necessary, for the treatment response evaluation (RA). Later in the course of the disease, ultrasonography may help in diagnosing some peripheral complications (tendinous ruptures, synovial cysts, superficial bursitis...) and is useful to guide corticosteroid injections (RA, spondylarthropathies). This article addresses the main ultrasonographic features of inflammatory rheumatic disorders and the role of ultrasonography relative to other imaging modalities (especially magnetic resonance [MR] imaging).

The value of pre-operative multicompartment pelvic floor ultrasonography: a 1-year prospective study.  

PubMed

Objective: Comprehensive assessment of the pelvic floor (PF) provides information and diagnoses of coexisting abnormalities that may affect operative decisions. Our aim was to establish if pre-operative PF ultrasonography (PFUS) in patients complaining of PF dysfunction can complement clinical findings and contribute to additional management strategies. Methods: Females were recruited from the urogynaecology/gynaecology clinics between July and October 2009 and underwent pelvic organ prolapse quantification (POPQ) by an independent examiner. PFUS was performed using two-dimensional (2D) transperineal ultrasound (TPUS), high-frequency 2D/three-dimensional (3D) endovaginal ultrasound (EVUS) using a biplane probe with linear and transverse arrays and a 360° rotational 3D-EVUS. The clinician performing PFUS was blinded to POPQ results. POPQ and PFUS were repeated at 1 year. Two clinicians analysed the scans independently. Results: 158 of 160 females had a POPQ and PFUS. 105 females had pelvic organ prolapse and/or incontinence and 53 asymptomatic females were controls. 26 additional ultrasound diagnoses were noted at baseline and 46 at 1 year using 2D-TPUS and EVUS. Only one female with additional diagnoses on PFUS needed surgical intervention for this condition. Conclusion: Multicompartment PFUS identifies additional conditions to that diagnosed on clinical assessment. However, it neither changes the initial surgical management nor the management at 1-year follow-up and therefore clinical assessment should not be substituted by PFUS. Advances in knowledge: PFUS can be helpful in providing additional information; however, it does not change the initial management of the patient and therefore should not replace clinical assessment.

Comparison of Ultrasonography and Fine Needle Aspiration Cytology in the Diagnosis of Malignant Breast Lesions  

PubMed Central

Introduction: Breast cancer is the most common cancer of women worldwide and usually presents as lump in the breast. Ultrasonography and Fine Needle Aspiration Cytology (FNAC) are two investigational tools often used to differentiate malignant breast lump from benign one. Aims and Objects: To find out and compare the sensitivity, specificity and predictive values of ultrasonography and FNAC in diagnosing malignant breast lump. Material and Methods: Patients who presented with clinically palpable breast lump at the department of Surgery, RIMS, India, from September, 2010 to August, 2012, were included. Recurrent lumps, breast abscess and cystic breast lumps were excluded. All the patients underwent Ultrasonographic evaluation using 7.5 MHz probe (©SIEMENS, Sonoline Versa Plus) at the department of Radiodiagnosis, RIMS and FNAC at the department of Pathology, RIMS. All the patients underwent excision of the lumps and tissues were sent for Histopathological examination. Sensitivity, specificity and predictive values of ultrasonography and FNAC were calculated taking Histopathological result as the gold standard. Values were compared. Results: Sixty patients with 62 breast lumps (40 benign and 22 malignant) were included. FNAC reported 42 lumps as benign and 19 as malignant and was indeterminate in 1 case. Ultrasonography reported 36 cases as benign, 18 as malignant and 6 as indeterminate; it failed to detect breast lump in 2 cases. Sensitivity, specificity, positive and negative predictive values of ultrasonography and FNAC in diagnosing malignant breast lump were respectively 94.74%, 100%, 100%, 97.22% and 90.48%, 100%, 100%, 95.24%. Conclusion: Ultrasonography and FNAC are 100% specific in diagnosing malignant breast lesion. Although Ultrasonography appears more sensitive than FNAC, the percentage of indeterminate report is higher with Ultrasonography.

Percutaneous Liver Biopsies Guided with Ultrasonography: A Case Series  

PubMed Central

Background Although liver biopsy is an easy procedure for hospitalized patients and outpatients, some complications may occur. Objectives To evaluate the efficiency, complications, safety and clinicopathological utility of ultrasonographic-guided percutaneous liver biopsy in diffuse liver disease. Patients and Methods In our retrospective study, we evaluated ultrasound-assisted needle biopsies that were performed in outpatients from October 2006 to July 2010. The liver biopsies were performed following one-night fasting using the tru-cut biopsy gun (18-20 gauge) after marking the best seen and hypovascular part of the liver, distant enough from the adjacent organs. Results A total of 1018 patients were referred to our radiology department. Most of the patients had hepatitis B (60.6%). The biopsy specimens were recorded and sent to our pathology department for histopathological examination. Conclusion According to the results of our series, percutaneous liver biopsy using the tru-cut biopsy gun guided by ultrasonography can be performed safely. We resolve that routine ultrasound of the puncture site is a quick, effective and safe procedure. The complication rate is very low. The US-assisted percutaneous liver biopsy should be used for all cases.

Bedside ultrasonography by emergency physicians for anterior talofibular ligament injury  

PubMed Central

Objective: Our objective was to study the accuracy of emergency physician (EP) performed bedside ultrasonography (BUS) in patients with suspected anterior talofibular ligament (ATFL) injury. Materials and Methods: After a 6-h training program, from January to December 2011, an EP used BUS to prospectively evaluate patients presenting to the emergency department (ED) with suspected ATFL injury. Then, patients underwent ankle X-ray and Magnetic Resonance (MR) imaging. Outcome was determined by official radiology reports of the MR imaging. BUS and MR imaging results were compared using Chi-square testing. Results: Of the 65 enrolled patients, 30 patients were BUS positive. Of these, MR imaging results agreed with the BUS findings in 30 patients. In 35 cases, BUS was negative, and 33 of these were corroborated by MR imaging. The sensitivity, specificity, positive predictive value, negative predictive value, and negative likelihood ratio for BUS were 93.8%, 100%, 100%, 94.3%, and 0.06%, respectively. The diagnostic accuracy of BUS was not statistically different from MR imaging (K = 0.938, P = 0.001). Conclusion: BUS for the diagnosis of ATFL injury is another application of BUS in the ED. EPs can diagnose ATFL injury using BUS with a high degree of accuracy.

Non-contact photoacoustic tomography and ultrasonography for brain imaging  

NASA Astrophysics Data System (ADS)

Photoacoustic tomography (PAT) and ultrasonography (US) of biological tissues usually rely on transducer arrays for the detection of ultrasound. Obtaining the best sensitivity requires a physical contact with the tissue using an intermediate coupling fluid (water or gel). This type of contact is a major drawback for several applications such as neurosurgery. Laser-ultrasonics is an established optical technique for the non-contact generation and detection of ultrasound in industrial materials. In this paper, the non-contact detection scheme used in laser-ultrasonics is adapted to allow probing of ultrasound in biological tissues while remaining below laser exposure safety limits. Both non-contact PAT (NCPAT) and non-contact US (NCUS) are demonstrated experimentally using a single-frequency detection laser emitting suitably shaped pulses and a confocal Fabry-Perot interferometer. It is shown that an acceptable sensitivity is obtained while remaining below the maximum permissible exposure (MPE) of biological tissues. Results obtained ex vivo with a calf brain specimen show that sub-mm endogenous and exogenous inclusions can be detected at depths exceeding 1 cm. When fully developed, the technique could be a unique diagnostic tool in neurosurgery providing deep imaging of blood vessels, blood clots and blood oxygenation.

Unlike cattle, ultrasound examination of the ovaries is not undertaken because failure to cycle during the normal season is rare in sheep and there are no common ovarian conditions causing acyclicity. Accurate diagnosis of foetal number has greatly improved the nutritional management of late gestation ewes over the past 30 years. Late gestation nutritional supply in response to foetal demand greatly reduces perinatal lamb mortality by ensuring lamb birthweight and ewe colostrum accumulation. The contents of vaginal prolapse have been determined using ultrasonography which has led to an improved method for correction. A retained foetus when second stage labour is considered to have been completed, and uterine torsion, can be identified during ultrasound examination allowing timely correction. Ultrasonographic examination of palpable scrotal abnormalities can provide much useful information particularly in the diagnosis of epididymitis, orchitis and testicular atrophy. PMID:22341010

Cardiac ultrasonography in structural abnormalities and arrhythmias. Recognition and treatment.  

PubMed Central

Fetal cardiac ultrasonography has become an important tool in the evaluation of fetuses at risk for cardiac anomalies. It can both guide prenatal treatment and assist the management and timing of delivery. We recommend that a fetal echocardiogram be done when there is a family history of congenital heart disease; maternal disease that may affect the fetus; a history of maternal drug use, either therapeutic or illegal; evidence of other fetal abnormalities; or evidence of fetal hydrops. The optimal timing of evaluation is 18 to 22 weeks' gestation. An entire range of structural cardiac defects can be visualized prenatally, including atrioventricular septal defect, ventricular septal defect, cardiomyopathy, ventricular outlet obstruction, and complex cardiac defects. The outcome for a fetus with a recognized abnormality is unfavourable, with less than 50% surviving the neonatal period. Fetal cardiac arrhythmias are also a common occurrence, 15% in the series described here. Premature atrial or ventricular contractions are most commonly seen and usually require no treatment. Supraventricular tachycardia can result in hydrops and require in utero treatment to prevent fetal demise. Complete heart block, particularly in association with structural heart disease, has a poor prognosis for fetal survival. Images

Non-contact photoacoustic tomography and ultrasonography for biomedical imaging  

NASA Astrophysics Data System (ADS)

Photoacoustic tomography (PAT) and ultrasonography (US) of biological tissues usually rely on ultrasonic transducers for the detection of ultrasound. For an optimum sensitivity, transducers require a physical contact with the tissue using a coupling fluid (water or gel). Such a contact is a major drawback in important potential applications such as surgical procedures on human beings and small animal imaging in research laboratories. On the other hand, laser ultrasonics (LU) is a well established optical technique for the non-contact generation and detection of ultrasound in industrial materials. In this paper, the remote optical detection scheme used in industrial LU is adapted to allow the detection of ultrasound in biological tissues while remaining below laser exposure safety limits. Both non-contact PAT (NCPAT) and non-contact US (NCUS) are considered experimentally using a high-power single-frequency detection laser emitting suitably shaped pulses and a confocal Fabry-Perot interferometer in differential configuration. It is shown that an acceptable sensitivity is obtained while remaining below the maximum permissible exposure (MPE) of biological tissues. Results were obtained ex vivo on chicken breast specimens with embedded inclusions simulating blood vessels optical properties. Sub-mm inclusions are readily detected at depths approaching 1 cm. The method is expected to be applicable to living tissues.

Magnetic resonance imaging and transvaginal ultrasound for determining fibroid burden: implications for clinical research  

PubMed Central

Objective(s) To compare MR and US imaging for uterine fibroid measurement Study Design Eighteen women undergoing hysterectomy for symptomatic fibroids underwent preoperative pelvic US and MR imaging. Resected fibroids were correlated with the images. Weighted kappa agreement statistics and Spearman correlations for patient characteristics were calculated. Results MR imaging identified 121 of 151 pathologically-confirmed fibroids, yielding 91% positive predictive value (PPV) (95%CI: 85%,95%) and 80% sensitivity (95%CI: 73%,86%). PPV and sensitivity for US were 97% (95%CI: 89%,100%) and 40% (95%CI: 32%,48%), respectively. Mean diameter-equivalent discrepancies between imaging and pathological measurements were 0.51±0.68 cm for MRI and 0.76±0.88 cm for US. Kappa statistics comparing imaging to pathology showed better agreement for MR than US (k=0.60 vs. 0.36). The number of fibroids detected by MR imaging predicted measurement errors (r=0.76; p=0.0002). Conclusion(s) Superior sensitivity and minimal measurement discrepancies suggest MR imaging should be preferentially utilized for assessing fibroids in clinical research studies.

The impact of the prenatal ultrasonography on birth of babies with Korean pediatric surgical index diseases  

PubMed Central

Purpose The purpose of this study is to examine the impact of prenatal ultrasonography (US) on the birth of babies with diseases listed on the Korean pediatric surgery index diseases (IDs). Methods Depending the ease of diagnosis using prenatal US, [diagnostic facility if prenatal US] IDs were divided into easily diagnosed (ED), not easily diagnosed (NED) and detected with difficulty (DD) groups. Five-year data were obtained for the total live birth number (TBN) from the Korean Statistical Information Service, and the actual birth number of IDs (ABNID) from the Korean Health Insurance Review and Assessment Service. The certified incidences of IDs (I) were obtained from a prestigious textbook of pediatric surgery. The estimated abortion rate (AR) of fetus in each group was obtained using the following formula: AR (%) = [1 - (ABNID)/(TBN × I)] × 100. Results The AR with all IDs was 38 to 77%. The AR was 78 to 93% for ED group, 38 to 66% for NED group and 0% for DD group. Conclusion In spite of high survival rates after treatment, the AR of each group depends on the ease of diagnosis using prenatal US in Korea. A recommendatory policy for the fetus with IDs should be urgently established after general consensus within the related medical societies.

Endoscopic ultrasonography for diagnosis and staging of pancreatic adenocarcinoma: key messages for clinicians.  

PubMed

Endoscopic ultrasound (EUS) is a technique that combines the potential of endoscopy, which enables the visual examination of the mucosal surface of any gastrointestinal (GI) tract, with ultrasonography. Despite diagnostic and therapeutic advance, pancreatic cancer (PC), in particular ductal adenocarcinoma, remains the most deadly of all GI malignancies, with a 5-years survival rate less than 1.8%. Moreover its incidence appears to be increasing and most patients present with advanced cancer either locally or with metastatic spread. Thus, all efforts must be oriented towards the need of an early diagnosis and to reliably identify patients who really can benefit from major surgical interventions. To date the most accurate imaging techniques for PC diagnosis and staging remain contrast-enhanced computed tomography and EUS. While the former should be the first choice in patients with suspected PC, EUS has the highest accuracy in detecting small lesions, in assessing tumor size and lymph nodes involvement. The possibility to obtain samples from suspicious lesions or lymph nodes, by means of EUS-guided fine-needle aspiration, makes this procedure an ideal staging modality for PC. Since an accurate preoperative evaluation is essential to choose the correct management strategy, EUS role is crucial. PMID:24727876

Accuracy of Endoscopic Ultrasonography for Determining the Treatment Method for Early Gastric Cancer  

PubMed Central

Background. Endoscopic resection (ER) for early gastric cancer (EGC) is a minimally invasive and curative treatment. The value of endoscopic ultrasonography (EUS) in determining the therapeutic strategy for EGC was assessed in this study. Materials and Methods. Pretreatment EUS was performed on 406?EGCs. The lesions were divided into the histological categories m/sm1 and sm2. The EUS-determined depths of invasion were classified as EUS-M/SM1, EUS-SM2, and EUS-MP or deeper. An analysis of the factors influencing the EUS-based depth determination was then conducted. Results. Most (92.8%) of the EUS-M/SM1 group belonged to the m/sm1 histological category. Ulcerated lesions, tumor size of larger than 2?cm, and the use of an ultrasound endoscope were independently associated with misdiagnosis of the depth of EGC by EUS. The ulcerated lesions had a significantly higher probability of overestimation. Conclusions. EUS is a useful method for determining the therapeutic strategy for EGC. Special attention should be paid not to overestimate the depth of cancer invasion when determining the ulcerated lesions and the type of curative procedure to be used.

Reproducibility of different screening classifications in ultrasonography of the newborn hip  

PubMed Central

Background Ultrasonography of the hip has gained wide acceptance as a primary method for diagnosis, screening and treatment monitoring of developmental hip dysplasia in infants. The aim of the study was to examine the degree of concordance of two objective classifications of hip morphology and subjective parameters by three investigators with different levels of experience. Methods In 207 consecutive newborns (101 boys; 106 girls) the following parameters were assessed: bony roof angle (?-angle) and cartilage roof angle (?-angle) according to Graf's basic standard method, "femoral head coverage" (FHC) as described by Terjesen, shape of the bony roof and position of the cartilaginous roof. Both hips were measured twice by each investigator with a 7.5 MHz linear transducer (SONOLINE G60S® ultrasound system, SIEMENS, Erlangen, Germany). Results Mean kappa-coefficients for the subjective parameters shape of the bony roof (0.97) and position of the cartilaginous roof (1.0) demonstrated high intra-observer reproducibility. Best results were achieved for ?-angle, followed by ?-angle and finally FHC. With respect to limits of agreement, inter-observer reproducibility was calculated less precisely. Conclusions Higher measurement differences were evaluated more in objective scorings. Those variations were observed by every investigator irrespective of level of experience.

Integration of three-dimensional ultrasonography in the prenatal diagnosis of amniotic band syndrome: A case report  

PubMed Central

Amniotic band syndrome is a rare disorder which is thought to be caused by early rupture of the amniotic membrane. The extent of the disease may vary from minor digital amputations to severe lethal anomalies. For many years in routine clinical practice, this syndrome has been diagnosed with two-dimensional ultrasonography. Evolving imaging techniques by means of three-dimensional ultrasonography gives the chance of early and accurate diagnosis of this devastating anomaly. By integrating three-dimensional ultrasonography to the suspected findings diagnosed in the two-dimensional ultrasonography allows us to predict possible outcomes and provides convenience in counselling. Herein we present a case of amniotic band syndrome diagnosed at 19 weeks of gestation with three-dimensional ultrasonography and pregnancy was terminated in the 20th week. Using three-dimensional ultrasonography in certain suspected foetal anomalies may provide the early diagnosis and more accurate knowledge about extent of the disease.

Evaluation of the diagnostic and prognostic utility of ultrasonography at first diagnosis of presumptive bovine respiratory disease  

PubMed Central

This project investigated the use of ultrasonography at first diagnosis of presumptive early bovine respiratory disease (BRD) in feedlot cattle from western Canada. One hundred seventy-four cattle (116 cases and 58 controls) at high risk of developing BRD were enrolled in a prospective longitudinal study over 2 y (2006–2007). Cattle with clinical signs relating to the respiratory system and assessed as sick at the time of feedlot arrival (arrival fever cases) or assessed as sick in the pen 3 to 30 d post-arrival (post-arrival fever cases, post-arrival no fevers cases) were eligible for enrollment. Control animals were identified at the time of case enrollments. Ultrasonography was done using a 3.5 sector transducer at enrollment and at 2, 4, and 6 wk post-enrollment. Lung lesions were identified at least 1 time over the course of the trial in 32/116 (28%) cases and 9/58 (16%) controls. At enrollment, lung lesions were identified in 20/115 (17%) cases and 2/55 (4%) controls (data unreadable n = 4). Post-arrival fever cases (14/48) were the most likely to have a lesion identified using ultrasound. In arrival fever cases, average daily gain (enrollment to last ultrasound, average 34 d) was improved (P = 0.007) in cattle identified with a lesion at enrollment using ultrasound compared with those not identified with a lesion at that time, potentially demonstrating the effects of gut fill at arrival weighing, as these sicker animals may have eaten less prior to arrival and, therefore, had more room for improvement in weight over time due to restoration of normal gut fill. None of the ultrasound time points explored (enrollment, 2, 4, or 6 wk post-enrollment) were associated with the animal health outcomes of interest (subsequent treatment, chronicity, wastage, or mortality) for cattle enrolled at arrival or post-arrival. Ultrasonography using a 3.5 sector transducer was not particularly effective as a prognostic/diagnostic tool for early detection of BRD, but may be useful in targeted populations of animals with respiratory disease of longer duration (such as chronic pens).

Bedside ultrasonography of musculoskeletal complications in brain injured patients  

PubMed Central

Introduction The aim of this study was to evaluate the role of bedside ultrasonography (US) in early diagnosis of musculoskeletal complications (MSC) of acquired brain injuries, to describe its incidence and US features in a neurorehabilitation setting. Materials and methods All 163 patients admitted in tertiary-level neurorehabilitation unit with diagnosis of stroke or severe brain injury (SBI), with symptoms or signs of musculoskeletal pathology, underwent bedside US. Results MSC were diagnosed in 51.5%. In 86.9% US clarified diagnosis and/or modified therapeutic approach. Shoulder pain was observed in 27.6%. US showed a shoulder subluxation in 73.3% and a frozen shoulder in 8.8% of painful shoulders. In all the cases rotator cuff abnormalities were noted. Wrist-hand syndrome was observed in 29.4%. US showed mild effusion in wrist joints and tendon sheaths and subcutaneous edema without significant vascularity. Neurogenic heterotopic ossification was observed in 1.8%. US demonstrated the “zone phenomenon” or heterogeneously hypoechoic mass with low resistance vessels within the lesions. Contractures and spasticity were observed in 18.4%. US allowed reliable guidance for Botulinum toxin A injection. Relapsing osteoarthritis and acute arthritis were diagnosed in 15.3% and 7.3% respectively. Patients with MSC had lower Functional Independence Measurement (FIM) and Katz index scores in discharge (p < 0.04 and p < 0.0294 respectively) and more length of hospital stay (p = 0.0024). Discussion Musculoskeletal pathology frequently complicates the course of acquired brain injuries and it delays functional recovery. Bedside US is a cheap and sensitive diagnostic tool and it can aid clinicians to define diagnosis and to choose therapeutic approach.

Contrast-Enhanced Harmonic Endoscopic Ultrasonography of Solid Pancreatic Lesions  

PubMed Central

Endoscopic ultrasonography is the best modality for pancreatic lesion evaluation as its superior spatial resolution allows small lesions to be identified and fine needle aspiration (FNA) cytology performed under ultrasound-guidance. Despite this, differentiating benign from malignant lesions remains a challenge as conventional ultrasound imaging is unable to differentiate lesions accurately and tissue yield is poorly diagnostic or limited in patients with the chronic inflammation. Contrast-harmonic technology uses a wide-band transducer capable of inducing sufficient acoustic energy to create harmonic microbubble oscillations of the newer second-generation ultrasound contrast agents (UCAs). These microbubbles are more stable, remaining within the intravascular component longer and emit significantly more harmonic content than surrounding tissue, thus allowing pancreatic parenchymal differentiation and microvascular architecture visualization. The use of UCAs is generally safe, but should be especially avoided in patients with unstable ischemic heart disease. During CH endosonography, pancreatic adenocarcinoma is commonly seen as an inhomogenous hypoenhancing lesion, focal pancreatitis as a hypo- or iso-enhancing lesion and neuroendocrine tumor as a hyperenhancing lesion. The presence of hyperenhancement is a strong predictor of non-adenocarcinoma etiology. Furthermore, in patients with the chronic pancreatitis or biliary stents that may obscure pancreatic inspection, the addition of contrast-harmonic endosonography to guide FNA cytology improves its diagnostic yield and accuracy. Quantitative analysis of perfusion through the time intensity curve is promising as an objective and accurate method to differentiate pancreatic lesions. Furthermore, studies are required to fully determine the role of contrast harmonic endosonography in the differential diagnosis of solid pancreatic lesions.

Does Prebiopsy, Nonsterile Ultrasonography Gel Affect Biopsy-Site Asepsis?  

SciTech Connect

Purpose. The purpose of this study was to determine the extent to which the use of nonsterile gel, prior to antiseptic procedures in ultrasonography (US)-guided percutaneous biopsies, results in contamination of the biopsy site. Materials and Methods. Patients referred for US-guided percutaneous biopsies were included in this study. Transmission material used for US evaluation before biopsy-site antiseptic procedures were performed was either nonsterile gel or sterile saline. Patients were randomly assigned to two groups: nonsterile gel (n = 30) and sterile saline (n = 30). Before the transmission material was used and after antiseptic procedures were performed, microbial swabs of a 10-cm{sup 2}-diameter area were obtained at the biopsy site. Swabs were also obtained from the gel, saline, and povidine-iodine. Inoculated specimen plates were incubated at 37{sup o}C under aerobic conditions, and the numbers of colony-forming units recorded. Nominal logistic regression analysis was used to calculate the odds of postantisepsis bacterial growth (after antiseptic procedures were performed) based on group, gender, coincidental disease (diabetes, chronic renal failure, and malignancy), biopsy-site location (head and neck or breast and abdomen), and local factors (skin fold, skin tag, and hair). Results. The following odds ratios (adjusted for the other variables) and their 95% confidence intervals were calculated: (1) group (2.9 [0.8-11.1]; p = 0.10); (2) gender (1.2 [0.3-5.2]; p = 0.78); (3) coincidental disease (7.6 [0.9-166.7]; p = 0.09); (4) biopsy site location (6.2 [1.4-31.3]; p = 0.02); and (5) local factors (7.0 [1.6-36.0]; p = 0.01). No bacterial growth occurred with swabs obtained from gel, povidine-iodine, or saline. Conclusion. We conclude that nonsterile gel used prior to percutaneous biopsy does not affect biopsy-site asepsis.

Clinical anatomy of the lingual nerve and identification with ultrasonography.  

PubMed

Our objective was to investigate the pathway of the lingual nerve and find out whether it can be identified using ultrasonography (US) intraorally. It is a dominant sensory nerve that branches from the posterior division of the mandibular aspect of the trigeminal nerve, and is one of the two most injured nerves during oral surgery. Its anatomy in the region of the third molar has been associated with lingual nerves of variable morphology. If surgeons can identify its precise location using US, morbidity should decrease. We searched published anatomical and specialty texts, journals, and websites for reference to its site and US. Cadavers (28 nerves) were dissected to analyse its orientation at the superior lingual alveolar crest (or lingual shelf). Volunteers (140 nerves) had US scans to identify the nerve intraorally. Our search of published books and journals found that descriptions of the nerve along the superior lingual alveolar crest were inadequate. We found no US studies of the nerve in humans. Dissections showed that the nerve was above (n=6, 21%) and below (n=22, 79%) the crest of the lingual plate. US scans showed 140 lingual nerves intraorally in 70 volunteers. The nerve lay either above or below the superior lingual alveolar crest, which led us to develop a high/low classification system. US can identify the lingual nerve and help to classify it preoperatively to avoid injury. Our results suggest that clinical anatomy of the lingual nerve includes the superior lingual alveolar crest at the third and second molars because of its surgical importance. US scans can successfully identify the nerve intraorally preoperatively. PMID:23182453

Carcinoma of the pancreatic head and periampullary region. Tumor staging with laparoscopy and laparoscopic ultrasonography.  

PubMed Central

OBJECTIVE: The authors performed a prospective evaluation of staging laparoscopy with laparoscopic ultrasonography in predicting surgical resectability in patients with carcinomas of the pancreatic head and periampullary region. SUMMARY BACKGROUND DATA: Pancreatic resection with curative intent is possible in a select minority of patients who have carcinomas of the pancreatic head and periampullary region. Patient selection is important to plan appropriate therapy and avoid unnecessary laparotomy in patients with unresectable disease. Laparoscopic ultrasonography is a novel technique that combines the proven benefits of staging laparoscopy with high resolution intraoperative ultrasound of the liver and pancreas, but which has yet to be evaluated critically in the staging of pancreatic malignancy. METHODS: A cohort of 40 consecutive patients referred to a tertiary referral center and with a diagnosis of potentially resectable pancreatic or periampullary cancer underwent staging laparoscopy with laparoscopic ultrasonography. The diagnostic accuracy of staging laparoscopy alone and in conjunction with laparoscopic ultrasonography was evaluated in predicting tumor resectability (absence of peritoneal or liver metastases; absence of malignant regional lymphadenopathy; tumor confined to pancreatic head or periampullary region). RESULTS: "Occult" metastatic lesions were demonstrated by staging laparoscopy in 14 patients (35%). Laparoscopic ultrasonography demonstrated factors confirming unresectable tumor in 23 patients (59%), provided staging information in addition to that of laparoscopy alone in 20 patients (53%), and changed the decision regarding tumor resectability in 10 patients (25%). Staging laparoscopy with laparoscopic ultrasonography was more specific and accurate in predicting tumor resectability than laparoscopy alone (88% and 89% versus 50% and 65%, respectively). CONCLUSIONS: Staging laparoscopy is indispensable in the detection of "occult" intra-abdominal metastases. Laparoscopic ultrasonography improves the accuracy of laparoscopic staging in patients with potentially resectable pancreatic and periampullary carcinomas. Images Figure 1. Figure 2. Figure 3.

Enhancement Patterns of Gastric Carcinoma on Contrast-Enhanced Ultrasonography: Relationship with Clinicopathological Features  

PubMed Central

The aim of this study was to assess the relationship between the enhancement patterns and clinicopathological features of gastric cancer using intravenous contrast-enhanced ultrasonography (CEUS). In this Ethics Committee-approved prospective study, five hundred fifty two patients with gastric cancer who gave informed consent were examined preoperatively with CEUS. The enhancement pattern of each tumor was analyzed visually. Gross and histopathological findings on the postoperative specimens were compared with the preoperative CEUS findings. The most common CEUS pattern in differentiated gastric cancer was homogeneous enhancement, whereas heterogeneous enhancement was the most common pattern in undifferentiated gastric cancer. The proportion of heterogeneous enhancement was significantly different between the two histological subtypes (Chi- square?=?146.735, P<0.001). The sensitivity and specificity of early heterogeneous enhancement on CEUS in diagnosing undifferentiated gastric cancer were 78.84% and 72.59% respectively. Gastric cancers with heterogeneous enhancement were more often Borrmann III and IV macroscopic types than those with homogeneous enhancement (66.56% vs. 30.80%, P<0.001), more commonly T3 and T4 depth of invasion than those with homogeneous enhancement (71.52% vs. 59.60%, P<0.05), more often showed lymphatic invasion than those with homogeneous enhancement (84.44% vs. 76.40%, P<0.05), and were less likely to receive curative gastrectomy than those with homogeneous enhancement (74.83% vs. 86.40%, P<0.005). The intra- and inter-observer reproducibility were both almost perfect for assessing enhancement patterns, with Kappa values of 0.916 (P<0.001) for intra-observer and 0.842 (P<0.001) for inter-observer reproducibility. CEUS provided detailed information about tumor vascularity and contrast enhancement patterns in gastric cancer. CEUS is promising as a new and useful method to predict the histological type of gastric cancer.

Efficacy of Ultrasonography-Guided Injections in Patients with Facet Syndrome of the Low Lumbar Spine  

PubMed Central

Objective To investigate the efficacy of ultrasonography (US)-guided injections in patients with low lumbar facet syndrome, compared with that in patients who received fluoroscopy (FS)-guided injections. Method Fifty-seven subjects with facet syndrome of the lumbar spine of the L4-5 and L5-S1 levels were randomly divided into two groups to receive intraarticular injections into the facet joint. One group received FS-guided facet joint injections and the other group received US-guided facet joint injections. Treatment effectiveness was assessed using a visual analogue scale (VAS), physician's and patient's global assessment (PhyGA, PaGA), and the modified Oswestry Disability Index (MODI). All parameters were evaluated four times: before injections, and at a week, a month, and three months after injections. We also measured, in both groups, how long it took to complete the whole procedure. Results Each group showed significant improvement from the facet joint injections on the VAS, PhyGA, PaGA, and MODI (p<0.05). However at a week, a month, and three months after injections, no significant differences were observed between the groups with regard to VAS, PhyGA, PaGA, and MODI (p>0.05). Statistically significant differences in procedure time were observed between groups (FS: 248.7±6.5 sec; US: 263.4±5.9 sec; p=0.023). Conclusion US-guided injections in patients with lumbar facet syndrome are as effective as FS-guided injections for pain relief and improving activities of daily living.

Characterization of solid focal pancreatic lesions using endoscopic ultrasonography with real-time elastography.  

PubMed

OBJECTIVES. The aim of this study was to evaluate the diagnostic potential of strain assessment in solid focal pancreatic lesions using real-time elastography in combination with endoscopic ultrasonography (EUS). MATERIAL AND METHODS. Forty-eight solid focal pancreatic lesions in 39 patients were included prospectively over a 3-year period and studied by EUS with real-time elastography (EUS-RTE). Lesions previously described as cystic by CT were not included. Distribution patterns of tissue strain were assessed using strain ratio (SR) measurements, continuous visual analog scale (VAS), and a visual categorical score (VCS), based on color coding of relative strain. Final diagnosis was based on histopathology, fine-needle aspiration cytology, and/or follow-up for ?6 months. RESULTS. The 48 lesions included 11 adenocarcinomas, 7 malignant neuroendocrine tumors (NETs), 11 benign or indeterminate NETs, 8 focal pancreatic lesions, 2 microcystic adenomas, and 9 other benign lesions. Malignant lesions had significantly higher median SR (7.05 vs. 1.56) and VAS scores (93.0 vs. 63.5) than benign lesions. A receiver operation characteristic curve analysis showed sensitivity of 67% and specificity of 71%, when using SR = 4.4 as a cut-off for malignancy. The highest SR values were found in two benign microcystic adenomas. CONCLUSIONS. EUS-RTE with SR measurements and VAS evaluation demonstrated a significant strain difference between benign and malignant lesions. However, the variation within the entities was substantial and some benign lesions presented with low strain. Benign lesions were generally characterized by a strain similar to reference tissue, whereas malignant lesions were harder. The recorded strain pattern in individual lesions must be interpreted with caution. PMID:24713038

Estimation of Gastrocnemius Muscle Volume Using Ultrasonography in Children with Spastic Cerebral Palsy  

PubMed Central

Purpose This study aimed to investigate useful parameters for estimating gastrocnemius (GCM) muscle volume (MV) using ultrasonography (US) and anthropometry in children with spastic cerebral palsy (CP). Materials and Methods Eighteen legs from nine children with spastic CP aged 2 to 6 years were investigated in this study. Tibial length (TL) of each leg was measured and muscle thickness (MT) and anatomical cross-sectional area (aCSA) of GCM muscles were assessed using US. The volume of the GCM was measured by magnetic resonance imaging (MRI) scans. The relationship of TL, MT, and aCSA with MV measured by MRI was investigated. Simple and multiple regression analyses were performed to establish muscle volume prediction equations. Results Resting MT, aCSA, and TL were highly related to MV of both medial and lateral head of GCM determined by MRI. The MV prediction equation based on simple regression analysis resulted in r2 values ranging from 0.591 to 0.832 (p<0.05). The r2 values were higher using aCSA as independent variable than using MT. The MV prediction equation based on multiple regression analysis resulted in r2 values ranging from 0.779 to 0.903 (p<0.05). However, the relatively high standard error of the estimate values ranged from 18.0-33.6% on simple regression and 15.5-25.6% on multiple regression. The contribution of aCSA was higher than that of MT for predicting MV of GCM. Conclusion Our study demonstrated the suitability of US assessment of aCSA and MT combined with TL for estimating MV of GCM in children with spastic CP and showed that aCSA is more useful parameter than MT.

Real-Time Visualization of Ultrasonography Guided Cubital Tunnel Injection: A Cadaveric Study  

PubMed Central

Objective To describe an ultrasonography-guided technique for cubital tunnel injection. Method The ulnar nerves from 12 elbows of 6 adult cadavers were scanned, and the cross-sectional areas of the ulnar nerves, cubital tunnel inlets and outlets were measured by using ultrasonography. All elbows were dissected after an ultrasonography-guided dye injection at the inlet of the cubital tunnel. The dissectors evaluated the spread of dye and the coloration of the nerve and remeasured the cross-sectional areas of the cubital tunnel inlets and outlets. Results After a real-time visualization of an ultrasonography-guided injection, the ulnar nerves were seperated from the medial groove for the ulnar nerve. All the ulnar nerves of the cadavers were successfully colored with the dye, from the inlet to oulet of the cubital tunnel. The post-injection cross-sectional areas were significantly larger than the pre-injection cross-sectional areas. No significant differences were detected in the post-injection cross-sectional areas of the cubital tunnel outlet and the ulnar nerve as compared with the pre-injection areas. Conclusion Clinicians should consider real-time visualization of ultrasonography for guided injection around the ulnar nerve at the inlet of the cubital tunnel.

Ultrasonography Accurately Evaluates the Dimension and Shape of the Pilonidal Sinus  

PubMed Central

PURPOSE To study the benefits of ultrasonography for detecting the borders of pilonidal sinus tissue. The correlation between physical and ultrasonographic examination was used for surgical planning. METHOD Between April and December 2004, 73 patients were recruited for this study. All patients were examined, and the borders of the sinus tissue were marked on the skin according to palpation before surgery. The surgeon also made a treatment plan considering the diseased tissue and marked a possible incision line. Patients were subsequently examined with ultrasonography. According to the ultrasonographic evaluation, the margins, extensions, and openings of pilonidal sinus tissue were determined and marked on the patient in a different color by a radiologist prior to surgery. The most suitable surgical treatment was decided according to the information obtained by ultrasonography. RESULTS The average age was 23.03 ± 3.05 (range 18–39) years. We found 81 lesions in 73 patients. Ultrasonographic borders of sinus tissue were similar to the borders marked by the surgeon in 56 patients (76.7%). In the remaining 17 patients (23.3%), ultrasonography detected branches or borders that distinctly exceeded the planned incision line. After ultrasonographic examination, the surgeon changed his incision line in 14 patients and the surgical intervention in 3 patients. CONCLUSION Palpation and methylene blue injection do not provide appropriate information in many patients. Our study revealed that pre-operative ultrasonography can improve the identification of the sinus tract and its branches when compared to palpation and methylene blue injection.

High-resolution ultrasonography for the diagnosis of brachial plexus root lesions.  

PubMed

The aim of this study was to investigate the feasibility of using high-resolution ultrasonography in the diagnosis of brachial plexus (BP) root lesions. A prospective study of ultrasonographic evaluation of BP nerve roots was performed in 37 patients with BP root lesions (29 with root injuries, 8 with tumors). The pre-operative ultrasonographic findings were compared with the surgical and pathohistological findings. All C5-7 roots were detected by ultrasonography in all patients, whereas 92% (68/74) of C8 and 51% (38/74) of T1 nerve roots were visualized. Among 29 patients with BP root avulsion, partial injuries or totally interrupted BP roots were detected in all patients. Cystic masses and neuromas were detected in 16 and 23 patients, respectively. In 8 patients with BP root tumors, 8 hypo-echoic masses were detected inside or partly outside of intervertebral foramina connecting to nerve roots. Surgical exploration revealed that there were 57 BP root avulsions in 29 patients. However, 2 T1 nerve root avulsions had been missed by pre-operative ultrasonography. Pathohistology revealed that all 8 BP root tumors pre-operatively diagnosed by ultrasonography were schwannomas. High-resolution ultrasonography can provide a convenient and accurate imaging modality for quick diagnosis and location of BP root lesions. PMID:24768481

Accuracy of Ultrasonography and Magnetic Resonance Imaging in the Diagnosis of Placenta Accreta  

PubMed Central

Purpose To evaluate the accuracy of ultrasonography and magnetic resonance imaging (MRI) in the diagnosis of placenta accreta and to define the most relevant specific ultrasound and MRI features that may predict placental invasion. Material and Methods This study was approved by the institutional review board of the French College of Obstetricians and Gynecologists. We retrospectively reviewed the medical records of all patients referred for suspected placenta accreta to two university hospitals from 01/2001 to 05/2012. Our study population included 42 pregnant women who had been investigated by both ultrasonography and MRI. Ultrasound images and MRI were blindly reassessed for each case by 2 raters in order to score features that predict abnormal placental invasion. Results Sensitivity in the diagnosis of placenta accreta was 100% with ultrasound and 76.9% for MRI (P?=?0.03). Specificity was 37.5% with ultrasonography and 50% for MRI (P?=?0.6). The features of greatest sensitivity on ultrasonography were intraplacental lacunae and loss of the normal retroplacental clear space. Increased vascularization in the uterine serosa-bladder wall interface and vascularization perpendicular to the uterine wall had the best positive predictive value (92%). At MRI, uterine bulging had the best positive predictive value (85%) and its combination with the presence of dark intraplacental bands on T2-weighted images improved the predictive value to 90%. Conclusion Ultrasound imaging is the mainstay of screening for placenta accreta. MRI appears to be complementary to ultrasonography, especially when there are few ultrasound signs.

Comparison of Long-term Clinical Outcomes according to the Change in the Rectocele Depth between Transanal and Transvaginal Repairs for a Symptomatic Rectocele  

PubMed Central

Purpose This study was aimed to compare the results of a transanal repair with those of a transvaginal levatorplasty and to determine the long-term clinical outcomes according to the change in the depth of the rectocele after the procedure. Methods Of 50 women who underwent a rectocele repair from March 2005 to February 2007, 26 women (group A) received a transanal repair, and 24 (group B) received a transvaginal repair with or without levatorplasty. At 12 months after the procedures, 45 (group A/B, 22/23 women) among the 50 women completed physiologic studies, including anal manometry and defecography, and clinical-outcome measurements. The variations of the clinical outcomes with changes in the depth of the rectocele were also evaluated in 42 women (group A/B, 20/22) at the median follow-up of 50 months. Results On the defecographic findings, the postoperative depth of the rectocele decreased significantly in both groups (group A vs. B, 1.91 ± 0.20 vs. 2.25 ± 0.46, P = 0.040). At 12 months after surgery, 17 women in each group (group A/B, 77/75%) reported improvement of their symptoms. However, only 11 and 13 women (group A/B, 55/59%) of groups A and B, respectively, maintained their improvement at the median follow-up of 50 months. Better results were reported in patients with a greater change in the depth of their rectocele (?4 cm) after the procedure (P = 0.001) Conclusion In both procedures, clinical outcomes might become progressively worse as the length of the follow-up is increased.

Comparison of ultrasonography, computerized tomography, and radionuclide imaging in the diagnosis of acute and chronic cholecystitis  

SciTech Connect

Seventy-five patients with abdominal pain in the right upper quadrant who were subsequently confirmed operatively and histologically to have acute or chronic cholecystitis underwent radionuclide imaging of the biliary tree, ultrasonography, and/or computerized tomography before operation. fifty-eight of the patients had acute cholecystitis and 17 had chronic cholecystitis and cholelithiasis. Analysis of our data indicates that ultrasonography is an accurate and better screening test than cholescintigraphy in the diagnosis of chronic cholecystitis and cholelithiasis, but it is less accurate in the detection of acute cholecystitis. On the other hand, radionuclide imaging is highly sensitive and specific in the early diagnosis of acute cholecystitis, but it is poor in the diagnosis of chronic cholecystitis and cholelithiasis unless the cystic duct is obstructed. CT scanning is more expensive than ultrasonography but may be extremely helpful in problematic cases such as the diagnosis of the cause in biliary obstruction or in imaging of the pancreas.

Routine trans-abdominal ultrasonography before laparoscopic sleeve gastrectomy: the findings.  

PubMed

Although some bariatric guidelines reserve pre-operative trans-abdominal ultrasonography screening for symptomatic patients and those with elevated liver enzymes, there has yet to exist a general consensus regarding this issue. Some centers still employ its use as a vital step in the workup of the bariatric patient. This study aims to observe the prevalent findings on routine pre-operative trans-abdominal ultrasonography when used as a screening tool prior to laparoscopic sleeve gastrectomy (LSG). All patients undergoing LSG were screened pre-operatively with trans-abdominal ultrasonography. A retrospective study was done of the pre-operative ultrasonography results of patients who underwent LSG at Amiri Hospital from 2008 to 2012. A total of 747 patients were included in the study, with a median age of 36 (15-68). Five hundred ninety (79.0 %) patients were females while 157 (21.0 %) were males, with an overall median body mass index (BMI) of 45 (30-90). Two hundred forty patients (32.1 %) had normal pre-operative ultrasonography results, 83 (11.1 %) were found to have gallstones, 427 (57.2 %) had fatty liver, and 55 (7.4 %) had other pathologies. There was no statistically significant association between BMI and gallstones (p?=?0.545) and BMI and fatty liver (p?=?0.418). Trans-abdominal ultrasonography screening prior to LSG revealed a wide range of findings but does not add significant information to the pre-operative workup of patients undergoing the procedure and should be reserved for indicated patients.

Value of Entheseal Ultrasonography and Serum Cartilage Oligomeric Matrix Protein in the Preclinical Diagnosis of Psoriatic Arthritis  

PubMed Central

Objective: To evaluate the utility of entheseal ultrasonography and serum COMP in the preclinical diagnosis of psoriatic arthritis. Methods: 60 psoriatic patients were divided into: 30 patients with psoriasis (group I) and 30 patients with psoriatic arthritis as control (group II). They underwent independent clinical and ultrasonographic examination of both lower limbs at the calcaneal insertions of Achilles tendons. Psoriatic arthritis disease activity and severity was assessed by modified DAS28 and Steinbrockers scores. Serum levels of COMP were measured for all patients by ELISA. Results: On clinical examination, no entheseal abnormalities were detected in group I while they were present in 23.3% of group II with statistically significant difference between them (P < 0.001). Ultrasonographic entheseal abnormalities were detected in 33.3% of group I and in 46.7% of group II with no significant difference between them (P > 0.05). Serum COMP were significantly elevated in group I and II with no statistically significant difference between them (mean ± SD 5.9 ± 3 and 6.8 ± 12 respectively, P > 0.05). Entheseal ultrasound was more specific (67%) while serum COMP was more sensitive (87%) in the preclinical diagnosis of psoriatic arthritis. Serum COMP levels were significantly correlated with CRP in both groups and with DAS28 and Steinbrockers scores in group II (P < 0.01). Conclusion: Entheseal ultrasonography and serum COMP levels may be used complementary to each other for preclinical diagnosis of psoriatic arthritis. Serum COMP seems to be promising prognostic marker for psoriatic arthritis patients.

Renal Tract Ultrasonography for Routine Surveillance in Spinal Cord Injury Patients  

PubMed Central

Objectives: To report the efficacy of a urinary tract surveillance regime based on annual renal tract ultrasound without routine use of urodynamic testing (UDS) in our population of spinal cord injury (SCI) patients managed with clean intermittent catheterization (CIC). Methods: Data was gathered retrospectively from the records of 48 SCI patients (40 males and 8 females). After establishing a safe system with initial urodynamics, renal ultrasonography was done annually for surveillance. UDS was repeated only when patients presented with new symptoms. The primary endpoint was the report of ultrasound findings at last follow-up. Findings of dilatation, calculi, scarring, and reflux were noted. Results: Mean follow-up was 6.8 years. By final follow-up, pelvicaliectasis was present in 4 (8%) subjects. Mild-moderate hydronephrosis was present in 3 (6%) subjects: 1 stable and 2 (4%) new compared to initial assessment. No severe cases of hydronephrosis were noted. Six (13%) subjects had renal/ureteral calculi. No new cases of renal cortical scarring or thinning were noted. One (2%) subject had high-grade reflux on UDS secondary to a double J stent. Conclusions: Data relating to the efficacy of sequential surveillance studies in SCI patients are scarce, thus there is great variability in urologic surveillance methods worldwide. Upper tract abnormalities detected in our patients were early consequences of acute obstruction rather than late manifestations of detrusor changes and could not have been prevented with more regular urodyamic testing. These results suggest that annual ultrasound monitoring without routine urodynamic testing is an effective surveillance strategy in SCI patients managed with CIC.

Sonographic features and ultrasonography-guided fine-needle aspiration of metastases to the thyroid gland  

PubMed Central

Purpose: To evaluate the characteristic ultrasonographic (US) features of metastatic carcinoma to the thyroid, and how accurate US features and ultrasonography-guided fine-needle aspiration (US-FNA) are for the diagnosis of thyroid metastases. Methods: Twenty-three thyroid lesions in 23 patients (mean age, 66.7 years; range, 46 to 85 years) that had been diagnosed as thyroid metastases were included. The composition, echogenicity, margin, shape, presence of calcifications, underlying parenchymal echotexture, and vascularity were analyzed in US images of the thyroid metastases. Final US assessments were categorized into probably benign and suspicious malignancy. The presence of suspicious metastatic cervical lymph nodes was noted. The medical records, US-FNA cytology, and pathology reports of these patients were retrospectively reviewed. Results: Of the 23 thyroid lesions, the general US appearance was mass-forming in 21 (91.3%) and non-mass-forming in 2 (8.7%). All 23 lesions showed a solid tumor composition. Common US features among the 21 mass-forming thyroid metastases were hypoechogenicity (81.0%), non-circumscribed margins (90.5%), no calcifications (76.2%), and parallel shape (81.0%). Suspicious cervical lymph nodes were present in 18 patients (78.3%). Of the 23 lesions, 21 (91.3%) were classified as suspicious malignancy, and 2 (8.7%) as probably benign. US-FNA showed diagnostic results specific for metastases in 21 of the 22 patients (95.5%) who had undergone US-FNA. Conclusion: Common US features in thyroid metastasis were hypoechogenicity, non-circumscribed margins, no calcifications, parallel shape, and the presence of suspicious cervical lymph nodes. US-FNA can be effectively used in the diagnosis of thyroid metastasis, preventing unnecessary surgery.

Validation of trans-rectal ultrasonography for counting preovulatory follicles in weaned sows.  

PubMed

The present study investigated the accuracy of trans-rectal ultrasonography (TRU) for assessing the exact number of preovulatory follicles (POFs, with a diameter from 6 to 10mm) present in the ovaries of weaned sows. The ovaries of 63 hormonally treated (1500 IU of eCG) weaned sows were checked with TRU (7.5-MHz multiple scan angle transducer) in two successive scanning sessions performed at 26-27 and 30-31h after the beginning of oestrus signs, and the maximum number of POFs were counted. Sows were subjected to laparoscopy (LAP) immediately after the last TRU scan to confirm the number of POFs. The differences (mean+/-S.D.) in the number of POFs counted with TRU and LAP on each ovary were analyzed as a whole and after sorting the ovaries into three classes according to the number of POFs visualized by LAP: (1) less than 7; (2) from 7 to 13; and (3) more than 13. A significant correlation (P<0.01) was found between TRU and LAP for both the whole data set (126 ovaries) and in each of the three ovarian classes. Despite the significant correlation, TRU underestimated the number of POFs by 1.40+/-1.67 compared with LAP (P<0.001). However, the underestimation varied among the ovarian classes. This difference was not significant (P>0.05) in class 1 and was significant (P<0.001) in classes 2 (1.11+/-1.30 less POFs than counted by TRU) and 3 (3.19+/-1.54 less POFs than counted by TRU). In conclusion, TRU is a valuable tool to count the number of POFs present in the ovaries of weaned sows, but a certain degree of underestimation should be expected when the number of POFs is large.

Impact of endoscopic ultrasonography and physician specialty on the management of patients with esophagus cancer  

PubMed Central

SUMMARY While endoscopic ultrasonography (EUS) and EUS-guided fine-needle aspiration (EUS-FNA) are the most accurate techniques for locoregional staging of esophageal cancer, little evidence exists that these innovations impact on clinical care. The objective on this study was to determine the frequency with which EUS and EUS-FNA alter the management of patients with localized esophageal cancer, and assess practice variation among specialists at a tertiary care center. Three gastroenterologists, three medical oncologists, three radiation oncologists and four thoracic surgeons were asked to independently report their management recommendations as the anonymized staging information of 50 prospectively enrolled patients from another study were sequentially disclosed on-line. Compared to initial management recommendations, that were based upon history, physical examination, upper endoscopy and CT scan results, EUS prompted a change in management 24% (95% CI: 12–36%) of the time; usually to a more resource-intensive approach (71%), for example from recommending palliation to recommending neoadjuvant chemoradiation therapy. EUS-FNA plus cytology results altered management an additional 8% (95% CI: 6–15%) of the time. Agreement between specialists ranged from fair (intraclass correlation [ICC = 0.32) to substantial (ICC = 0.65); improving with additional information. Among specialists, agreement was greatest for patients with stage I disease. EUS and EUS-FNA changed patient management the most for patients with stages IIA, IIB or III disease. EUS, with or without FNA, significantly impacts the management of patients with localized esophageal cancer. With respect to the optimal treatment for each patient, agreement among physicians incrementally increases with endoscopic ultrasound results. Specialty training appears to influence therapeutic decision-making behavior.

Role of kidney Doppler ultrasonography in the diagnosis and management of anuric kidney failure.  

PubMed

Kidney perfusion can be acutely compromised by many factors including reduced systemic blood pressure and elevated intra-abdominal pressure. We present a case of near complete absence of kidney perfusion in a 57-year-old man with heart failure and new onset ascites. The renal perfusion defect was directly detected by Doppler ultrasonography. Immediate decompression with large-volume paracentesis restored the kidney perfusion and kidney function. This case illustrates that renal ultrasonography with Doppler flow analysis in appropriate settings can serve as an important adjunct in the diagnosis and treatment of acute oligoanuric kidney failure. Timely reversal of the perfusion defect can rescue kidney function. PMID:23253907

The value of ultrasonography alone in screening surveys of cystic echinococcosis in children in Turkey.  

PubMed

A total of 1,205 primary school children were examined for cystic echinococcosis in five villages of Manisa, Turkey, to evaluate the efficacy of diagnostic methods of this infection in community-based screening surveys. Six hundred and thirty children from three villages, examined by a portable ultrasound scanner, chest microfilm and serological methods (ELISA, indirect hemagglutination) in our previous study, were designated as Study Group 1; and 575 children, from two adjacent villages, examined by ultrasonography alone in the present study, were designated as Study Group 2. In Study Group 1, hepatic cystic echinococcosis was detected in two cases (0.3%) by ultrasonography, while 43 (8.9%) and 49 (10.1%) cases were found to be positive for cystic echinococcosis by ELISA and indirect hemagglutination, respectively. Three of 575 children (0.5%) were diagnosed with cystic echinococcosis (two hepatic and one renal involvement) by ultrasonography alone in Study Group 2; and lung lesions were later detected in both cases with liver involvement by chest radiography. Our results suggested that serological tests may be beneficial in suspected cases for confirmation and differential diagnosis, but have some drawbacks, such as discrepancy in results and high false seropositivity rates. Chest microfilm is not easy in field studies and exposure to X-ray is undesirable. As a reliable, simple, inexpensive and rapid technique, ultrasonography alone is recommended to be used in community-based screening surveys for cystic echinococcosis with confirmatory tests for suspected cases found during the screening program.

It is due to a defect in fusion of the anterior chest wall resulting in an extrathoracic location of the heart. We report prenatal 2-dimensional (2D) and 3D ultrasonography diagnosis and postnatal autoptic findings of an isolated ectopia cordis with tricuspid atresia. Ectopia cordis prenatal diagnosis is

Comparison of the sensitivity for detecting foreign bodies among conventional plain radiography, computed tomography and ultrasonography  

PubMed Central

Objective The purpose of this study was to compare the sensitivity for detecting foreign bodies among conventional plain radiography, CT and ultrasonography in in vitro models. Methods Seven different materials were selected as foreign bodies with dimensions of approximately 1×1×0.1 cm. These materials were metal, glass, wood, stone, acrylic, graphite and Bakelite. These foreign bodies were placed into a sheep's head between the corpus mandible and muscle, in the tongue and in the maxillary sinus. Conventional plain radiography, CT and ultrasonography imaging methods were compared to investigate their sensitivity for detecting these foreign bodies. Results Metal, glass and stone can be detected with all the visualization techniques used in the study in all of the zones. In contrast to this, foreign bodies with low radiopacity, which could be detected in air with CT, became less visible or almost invisible in muscle tissue and between bone and muscle tissue. The performance of ultrasonography for visualizing foreign bodies with low radiopacity is relatively better than CT. Conclusions Ultrasonography detects and localizes superficial foreign bodies with low radiopacity in the tissues of the body more effectively than CT and conventional plain radiography. However, CT is a more effective technique for visualization of foreign bodies in air than ultrasound and conventional plain radiography.

Rapid detection of pneumothorax by ultrasonography in patients with multiple trauma  

PubMed Central

Introduction Early detection of pneumothorax in multiple trauma patients is critically important. It can be argued that the efficacy of ultrasonography (US) for detection of pneumothorax is enhanced if it is performed and interpreted directly by the clinician in charge of the patients. The aim of this study was to assess the ability of emergency department clinicians to perform bedside US to detect and assess the size of the pneumothorax in patients with multiple trauma. Methods Over a 14 month period, patients with multiple trauma treated in the emergency department were enrolled in this prospective study. Bedside US was performed by emergency department clinicians in charge of the patients. Portable supine chest radiography (CXR) and computed tomography (CT) were obtained within an interval of three hours. Using CT and chest drain as the gold standard, the diagnostic efficacy of US and CXR for the detection of pneumothorax, defined as rapidity and accuracy (sensitivity, specificity, positive predictive value, negative predictive value), were compared. The size of the pneumothorax (small, medium and large) determined by US was also compared to that determined by CT. Results Of 135 patients (injury severity score = 29.1 ± 12.4) included in the study, 83 received mechanical ventilation. The time needed for diagnosis of pneumothorax was significantly shorter with US compared to CXR (2.3 ± 2.9 versus 19.9 ± 10.3 minutes, p < 0.001). CT and chest drain confirmed 29 cases of pneumothorax (21.5%). The diagnostic sensitivity, specificity, positive and negative predictive values and accuracy for US and radiography were 86.2% versus 27.6% (p < 0.001), 97.2% versus 100% (not significant), 89.3% versus 100% (not significant), 96.3% versus 83.5% (p = 0.002), and 94.8% versus 84.4% (p = 0.005), respectively. US was highly consistent with CT in determining the size of pneumothorax (Kappa = 0.669, p < 0.001). Conclusion Bedside clinician-performed US provides a reliable tool and has the advantages of being simple and rapid and having higher sensitivity and accuracy compared to chest radiography for the detection of pneumothorax in patients with multiple trauma.

Laparoscopy and laparoscopic ultrasonography avoid exploratory laparotomy in patients with hepatocellular carcinoma.  

PubMed Central

OBJECTIVE: This prospective study evaluates the value of laparoscopy and laparoscopic ultrasonography (USG) in avoiding exploratory laparotomy in patients with hepatocellular carcinoma (HCC). SUMMARY BACKGROUND DATA: Laparotomy and intraoperative USG is the gold standard to determine the resectability of HCC. No palliation can be offered to patients found to have unresectable disease, and the surgical exploration causes morbidity. METHODS: From June 1994 to June 1996, 110 of 370 patients (30%) with HCC were considered candidates for possible hepatic resection. Preoperative liver function was assessed using Child-Pugh grading and indocyanine green retention test. The extent of disease was evaluated with radiologic studies, including percutaneous USG, computerized tomography scan, and hepatic angiogram. Nineteen patients were excluded from the study because of previous upper abdominal surgery (n = 12), ruptured tumors (n = 4), refusal by patients (n = 2), and instrument failure (n = 1). Laparoscopy and laparoscopic USG was performed on 91 patients immediately before a planned laparotomy aiming at hepatic resection. Laparotomy was aborted when definite evidence of unresectable disease was found on laparoscopic examination. RESULTS: The median time required for laparoscopy and laparoscopic USG was 30 minutes (range, 10 to 120 minutes). Fifteen patients had evidence of unresectable disease on laparoscopic examination. Among the remaining 76 patients who underwent laparotomy, 9 had exploration only and 67 underwent hepatic resection. Thus, exploratory laparotomy was avoided in 63% of patients with unresectable disease. The laparoscopic examination failed to confirm unresectable disease more often when the tumor was >10 cm in diameter. The procedure accurately assessed the adequacy of the liver remnant and the presence of intrahepatic metastases, but it was less sensitive in determining the presence of tumor thrombi in major vascular structures and the extent of invasion of adjacent organs. When unresectable disease was detected without the need for a laparotomy, the postoperative recovery was faster, and the nonoperative treatment for the tumor could be initiated earlier. CONCLUSIONS: Laparoscopy with laparoscopic USG avoids unnecessary laparotomy in patients with HCC and should precede a planned laparotomy aiming at hepatic resection.

Effectiveness of routine ultrasonography in detecting fetal structural abnormalities in a low risk population.  

PubMed Central

OBJECTIVE--To review the efficacy of routine prenatal ultrasonography for detecting fetal structural abnormalities. DESIGN--Retrospective study of the ultrasonographic findings and outcome of all pregnancies in women scanned in 1988-9. SETTING--Maternity ultrasonography department of a district general hospital. SUBJECTS--8785 fetuses. MAIN OUTCOME MEASURES--Correlation of prenatal ultrasonographic findings with outcome in the neonate. RESULTS--8733 babies were born during 1988-9, and 52 pregnancies were terminated after a fetal malformation was identified. 8432 (95%) of the fetuses were examined by ultrasonography in the second trimester. 130 fetuses (1.5%) were found to have an abnormality at birth or after termination of pregnancy, 125 of which had been examined in the second trimester. In 93 cases the abnormality was detected before 24 weeks (sensitivity 74.4%, 95% confidence interval to 66.7% to 82.1%. Two false positive diagnoses occurred, in both cases the pregnancies were not terminated and apparently normal infants were born. This gives a specificity of 99.98% (99.9% to 99.99%). The positive predictive value of ultrasonography in the second trimester was 97.9% (92.6% to 99.7%). Of the 125 abnormalities, 87 were lethal or severely disabling; 72 of the 87 were detected by the routine screening programme (sensitivity 82.8%, 73.2% to 90.0%). CONCLUSION--Routine fetal examination by ultrasonography in a low risk population detects many fetal structural abnormalities but can present several dilemmas in counselling.

Transvaginal follicular aspiration and embryo development in superstimulated early postpartum beef cows and subsequent fertility after artificial insemination.  

PubMed

This study was conducted to investigate in early postpartum suckled beef cows with and without FSH pre-stimulation: (i) the influence of the postpartum period on the number and quality of oocytes recovered by ovum pick-up (OPU), (ii) the overall efficiency of the OPU/IVP embryos from days 30 to 80 postpartum and (iii) if repeated OPU negatively affect fertility following a fixed-time artificial insemination protocol. After parturition suckled Angus cows (n = 30) were divided in three groups (n = 10 group(-1)). All cows were anestrous at the commencement of experimental treatments (30.0 +/- 3.2 days postpartum, mean +/- SD; range 25-34 days). Group 1 treatments included: dominant follicle ablation (DFA), FSH treatment and OPU procedure 5 days after DFA. A total of 9 mg FSH (Ovagen) was administered s.c. once a day over 2 days at equal doses (4.5 + 4.5mg). For fertility test the cows received an intravaginal progesterone treatment from Days 78 to 86 postpartum and were fixed-time artificially inseminated (FTAI) at 56 and 72 h after device removal. Group 2: as cited for Group 1 with no FSH treatment. In both groups, OPU was repeated four times (Days 35, 49, 63 and 77 postpartum) and the collected oocytes classified as viable were in vitro matured, fertilized and presumptive embryos cultured for 8 days. Group 3 (Control FTAI): cows that had not previously aspirations were FTAI as Groups 1 and 2. Pregnancy was diagnosed by means ultrasonography 39 days after FTAI. The numbers (mean +/- SEM) of follicles visible and aspirated at the time of OPU in FSH-treated cows were greater (P < 0.05) than in non-treated cows (10.6 +/- 0.6 and 8.4 +/- 0.4 vs. 8.0 +/- 0.5 and 4.6 +/- 0.3, respectively). Following FSH treatment, the number (mean +/- SEM) of recovered oocytes per cow per OPU session and percentage of viable oocytes were greater in the treated (P < 0.05) than in non-treated animals (3.0 +/- 0.1 and 39.5% vs. 1.5 +/- 0.1 and 30.0%). The cleavage and embryo development rates were similar (P > 0.05) for both groups (14.8 and 6.4% vs. 16.6 and 5.5%). After FTAI the pregnancy rates were not different (P > 0.05) among groups (70, 60 and 90% for Groups 1, 2 and 3, respectively). We can conclude that (1) FSH-treated suckled postpartum cows can be a source of oocytes for in vitro fertilization and (2) repeated DFA/OPU applied during postpartum period did not affect the subsequent fertility following FTAI.

Intra- and early postpartum ultrasonography: a review. Part I.  

PubMed

The objective of this article is to review current literature pertaining to intra- and early postpartum sonography. All the manuscripts published in the English language regarding this topic were selected from a MEDLINE search from 1966 through August 1997. Additional sources were identified through cross-referencing. Currently, intra- and early postpartum sonography may be performed for either maternal or fetal indications. Maternal indications include cervical assessment in preterm labor/rupture of membranes, assessment of the lower uterine segment, size and position of uterine fibroids, guided-placement of central venous or pulmonary artery catheters, detection of intraoperative venous air embolism, deep venous thrombosis, assist management of the third-stage of labor, postpartum hemorrhage or febrile morbidity. Fetal indications include an anatomical survey in patients presenting without prenatal care, verification of fetal presentation, estimated fetal weight, assessment of the breech-presenting fetus, external cephalic version, management of delivery of the second-twin, and internal podalic version. Doppler flow velocimetry is a useful tool in depicting both maternal and fetal intrapartum physiologic changes. We conclude that intra- and early postpartum sonography is an established versatile diagnostic and interventional-guiding modality for many obstetric conditions and should be readily available on labor and delivery suites.

Time-Intensity Curve Parameters in Rectal Cancer Measured Using Endorectal Ultrasonography with Sterile Coupling Gels Filling the Rectum: Correlations with Tumor Angiogenesis and Clinicopathological Features  

PubMed Central

The primary aim of this study was to investigate the relationship between contrast-enhanced ultrasonography (CEUS) imaging parameters and clinicopathological features of rectal carcinoma and assess their potential as new radiological prognostic predictors. A total of 66 rectal carcinoma patients were analyzed with the time-intensity curve of CEUS. The parameter arrival time (AT), time to peak enhancement (TTP), wash-in time (WIT), enhanced intensity (EI), and ascending slope (AS) were measured. Microvessel density (MVD) was evaluated by immunohistochemical staining of surgical specimens. All findings were analysed prospectively and correlated with tumor staging, histological grading, and MVD. The mean values of AT, TTP, WIT, EI, and AS value of the rectal carcinoma were 10.84 ± 3.28?s, 20.61 ± 5.52?s, 9.78 ± 2.83?s, 28.68 ± 4.67?dB, and 3.20 ± 1.10, respectively. A positive linear correlation was found between the EI and MVD in rectal carcinoma (r = 0.295, P = 0.016), and there was a significant difference for EI among histological grading (r = ?0.264, P = 0.007). EI decreased as T stage increased with a trend of association noted (P = 0.096). EI of contrast enhanced endorectal ultrasonography provides noninvasive biomarker of tumor angiogenesis in rectal cancer. CEUS data have the potential to predict patient prognosis.

Comparison of ultrasonography, computed tomography and 99mTc liver scan in diagnosis of Budd-Chiari syndrome.  

PubMed Central

Ultrasonography, computed tomography and 99mTc liver scanning are all useful in diagnosis of patients with the Budd-Chiari syndrome. In a study to determine their comparative value characteristic findings were recorded in all nine patients at ultrasonography and in seven patients at computed tomography. In contrast 99mTc liver scan showed a characteristic pattern in only one of eight patients. In our experience intrahepatic venous abnormalities were seen better at ultrasonography than at computed tomography. In addition, abnormality in the direction of blood flow could be detected by pulsed Doppler examination. Ultrasonography is relatively inexpensive, readily accessible, does not require administration of radiation or contrast agents and therefore should be the primary non-invasive investigation of patients with Budd-Chiari syndrome, or those at risk of developing it.

Usefulness and Limitation of Ultrasonography in the Diagnosis of Intestinal Intussusception in Cows  

PubMed Central

The present study was conducted on 6 chronically ill Jersey/Red Sindhi cross-bred cows, which were suspected for intestinal obstruction on the basis of history and clinical signs. These cows were ultimately diagnosed with intestinal intussusception based on a combination of clinical, ultrasonographic and surgical examinations. “Bull's eye lesion” was the most prominent ultrasonographic finding, diagnostic for intussusception either trans-abdominally or transrectally. Dilated intestinal loops greater than 3.1?cm (mean ± SE, 4.41 ± 0.25) were imaged in the lower flank and the 12th intercostal space on the right side. Ultrasonography proved to be a useful tool in supplementing and substantiating the transrectal findings in cases of the bovine intestinal intussusception. However, ultrasonography was not significantly helpful where transrectal examination of the cows did not reveal any suspected intestinal mass.

Pelvic congenital arteriovenous malformation diagnosed by transrectal ultrasonography: A case report  

PubMed Central

Arteriovenous malformations (AVMs) of the pelvis are relatively rare and difficult to treat because of multiple and extensive feeding vessels. We report the case of a 69-year-old male with pelvic congenital AVM that was detected during tests for dysuria. He visited our hospital complaining of voiding difficulty. Digital rectal examination revealed a pulsating mass that was palpable on the right side of the prostate. Transrectal ultrasonography showed multiple hypoechoic lesions adjacent to the prostate and colour Doppler ultrasonography revealed the flow regions corresponded to the hypoechoic lesions. Computed tomography demonstrated large-to-small tubular vessels adjacent to the prostate, while pelvic angiography showed many small feeder arteries extending mainly from the right internal iliac artery. He was diagnosed as having pelvic congenital AVM. Uroflowmetry revealed slight voiding difficulty without residual urine. The patient decided against treatment and requested we monitor his clinical course.

Duodenal Mucosa-Associated Lymphoid Tissue Lymphomas: Two Cases and the Evaluation of Endoscopic Ultrasonography  

PubMed Central

Mucosa-associated lymphoid tissue lymphoma mainly arises in the stomach, with fewer than 30% arising in the small intestine. We describe here two cases of primary duodenal mucosa-associated lymphoid tissue lymphoma which were evaluated by endoscopic ultrasonography. A 52-year-old man underwent endoscopy due to abdominal pain, which demonstrated a depressed lesion on duodenal bulb. Endoscopic ultrasonographic finding was hypoechoic lesion invading the submucosa. The other case was a previously healthy 51-year-old man. Endoscopy showed a whitish granular lesion on duodenum third portion. Endoscopic ultrasonography image was similar to the first case, whereas abdominal computed tomography revealed enlargement of multiple lymph nodes. The first case was treated with eradication of Helicobacter pylori, after which the mucosal change and endoscopic ultrasound finding were normalized in 7 months. The second case was treated with cyclophosphamide, vincristine, prednisolone, and rituximab every 3 weeks. After 6 courses of chemotherapy, the patient achieved complete remission.

Advanced Clinical Usefulness of Ultrasonography for Diseases in Oral and Maxillofacial Regions  

PubMed Central

Various kinds of diseases may be found in the oral and maxillofacial regions and various modalities may be applied for their diagnosis, including intra-oral radiography, panoramic radiography, ultrasonography, computed tomography, magnetic resonance imaging, and nuclear medicine methods such as positron emission tomography. Of these modalities, ultrasound imaging is easy to use for the detection of noninvasive and soft tissue-related diseases. Doppler ultrasound images taken in the B-mode can provide vascular information associated with the morphology of soft tissues. Thus, ultrasound imaging plays an important role in confirming the diagnosis of many kinds of diseases in such oral and maxillofacial regions as the tongue, lymph nodes, salivary glands, and masticatory muscles. In the present article, we introduce three new applications of ultrasonography: guided fine-needle aspiration, measurement of tongue cancer thickness, and diagnosis of metastasis to cervical lymph nodes.

Diagnosis of a sigmoid volvulus in pregnancy: ultrasonography and magnetic resonance imaging findings  

PubMed Central

Sigmoid volvulus complicating pregnancy is a rare, non-obstetric cause of abdominal pain that requires prompt surgical intervention (decompression) to avoid intestinal ischemia and perforation. We report the case of a 31-week pregnant woman with abdominal pain and subsequent development of constipation. Preoperative diagnosis was achieved using magnetic resonance imaging and ultrasonography: the large bowel distension and a typical whirl sign - near a sigmoid colon transition point - suggested the diagnosis of sigmoid volvulus. The decision to refer the patient for emergency laparotomy was adopted without any ionizing radiation exposure, and the pre-operative diagnosis was confirmed after surgery. Imaging features of sigmoid volvulus and differential diagnosis from other non-obstetric abdominal emergencies in pregnancy are discussed in our report, with special emphasis on the diagnostic capabilities of ultrasonography and magnetic resonance imaging.

Diagnostic Value of Ultrasonography and Magnetic Resonance Imaging in Ulnar Neuropathy at the Elbow  

PubMed Central

Aim. To evaluate the diagnostic value of ultrasonography and magnetic resonance imaging (MRI) in patients with ulnar neuropathy at the elbow (UNE). Methods. We prospectively performed electrodiagnostic, ultrasonographic, and MRI studies in UNE patients and healthy controls. Three cross-sectional area (CSA) measurements of the ulnar nerve at multiple levels along the arm and maximum CSA(-max) were recorded. Results. The ulnar nerve CSA measurements were different between the UNE severity grades (P < 0.05). CSA-max had the greatest sensitivity (93%) and specificity (68%). Moreover, CSA-max ?10?mm2 defined the severe UNE cases (sensitivity/specificity: 82%/72%). In MRI, ulnar nerve hyperintensity had the greatest sensitivity (90%) and specificity (80%). Conclusion. Ultrasonography using CSA-max is sensitive and specific in UNE diagnosis and discriminating the severe UNE cases. Furthermore, MRI particularly targeting at increased signal of the ulnar nerve can be a useful diagnostic test of UNE.

We report a case of surgically treated chest wall schwannoma without entering the pleural space utilizing ultrasonography. A 19-year-old woman was admitted for an abnormal shadow on a routine health checkup. Roentgenologic examination of the chest showed a 2 cm left chest wall mass. Chest computed tomography revealed a heterogeneous mass with obtuse angles characteristic of a pleural-based lesion. Under general anesthesia, the patient was placed in the right decubitous position. Chest wall ultrasonography defined a mass in the intercostal space. A 2.5 cm skin incision was made on the tumor. The tumor arising from the intercostal nerve was surgically removed without entering the pleural space. The pathological examination revealed a benign schwannoma. Postoperative course was uneventful and she discharged 2 days later. Six years later the patient is well without recurrence. PMID:19588826

The relationship between inferior vena cava diameter measured by bedside ultrasonography and central venous pressure value  

PubMed Central

Objective: We aimed to present inferior vena cava (IVC) diameter as a guiding method for detection of relationship between IVC diameter measured noninvasively with the help of ultrasonography (USG) and central venous pressure (CVP) and evaluation of patient's intravascular volume status. Methods: Patients over the age of 18, to whom a central venous catheter was inserted to their subclavian vein or internal jugular vein were included in our study. IVC diameter measurements were recorded in millimeters following measurement by the same clinician with the help of USG both at the end-inspiratory and end-expiratory phase. CVP measurements were viewed on the monitor by means of piezoelectric transducer and recorded in mmHg. SPSS 18.0 package program was used for statistical analysis of data. Results: Forty five patients were included in the study. The patients had the diagnosis of malignancy (35.6%), sepsis (13.3%), pneumonia, asthma, chronic obstructive pulmonary disease (11.1%). 11 patients (24.4%) required mechanical ventilation while 34 (75.6%) patients had spontaneous respiration. In patients with spontaneous respiration, a significant relationship was found between IVC diameters measured by ultrasonography at the end of expiratory and inspiratory phases and measured CVP values at the same phases (for expiratory p = 0.002, for inspiratory p= 0.001). There was no statistically significant association between IVC diameters measured by ultrasonography at the end of expiration and inspiration and measured CVP values at the same phases in mechanically ventilated patients. Conclusions: IVC diameter measured by bedside ultrasonography can be used for determination of the intravascular volume status of the patients with spontaneous respiration.

The Predictive Diagnostic Value of Serial Daily Bedside Ultrasonography for Severe Dengue in Indonesian Adults  

PubMed Central

Background Identification of dengue patients at risk for progressing to severe disease is difficult. Significant plasma leakage is a hallmark of severe dengue infection which can suddenly lead to hypovolemic shock around the time of defervescence. We hypothesized that the detection of subclinical plasma leakage may identify those at risk for severe dengue. The aim of the study was to determine the predictive diagnostic value of serial ultrasonography for severe dengue. Methodology/Principal Findings Daily bedside ultrasounds were performed with a handheld ultrasound device in a prospective cohort of adult Indonesians with dengue. Timing, localization and relation to dengue severity of the ultrasonography findings were determined, as well as the relation with serial hematocrit and albumin values. The severity of dengue was retrospectively determined by WHO 2009 criteria. A total of 66 patients with proven dengue infection were included in the study of whom 11 developed severe dengue. Presence of subclinical plasma leakage at enrollment had a positive predictive value of 35% and a negative predictive value of 90% for severe dengue. At enrollment, 55% of severe dengue cases already had subclinical plasma leakage, which increased to 91% during the subsequent days. Gallbladder wall edema was more pronounced in severe than in non-severe dengue patients and often preceded ascites/pleural effusion. Serial hematocrit and albumin measurements failed to identify plasma leakage and patients at risk for severe dengue. Conclusions/Significance Serial ultrasonography, in contrast to existing markers such as hematocrit, may better identify patients at risk for development of severe dengue. Patients with evidence of subclinical plasma leakage and/or an edematous gallbladder wall by ultrasonography merit intensive monitoring for development of complications.

Extramedullary Plasmacytoma of the Pancreas Diagnosed Using Endoscopic Ultrasonography-Guided Fine Needle Aspiration  

PubMed Central

Extramedullary plasmacytoma involves organs outside the bone marrow; however, involvement of the pancreas is rare. We recently experienced a case of extramedullary plasmacytoma of the pancreas that was diagnosed by endoscopic ultrasonography-guided fine needle aspiration (EUS-FNA). EUS-FNA, which has a high diagnostic accuracy and an excellent safety profile, is the modality of choice for establishing tissue diagnosis. We report a case of extramedullary plasmacytoma of the pancreas diagnosed using EUS-FNA.

Contrast-enhanced ultrasonography follow-up after radiofrequency ablation in normal rabbit kidney  

PubMed Central

Introduction The aim of this study was to evaluate the diagnostic performance of SonoVue-enhanced ultrasonography in the follow-up of rabbit kidney lesions induced by percutaneous radiofrequency ablation. Material and methods New Zealand rabbits (28) underwent percutaneous radiofrequency ablation (RFA) to generate renal lesions. Lesions were evaluated by conventional 2D ultrasound and contrast-enhanced ultrasonography (CEUS) at 1 day, 1 week, 1 month and 3 months after RFA, and the results were compared to gross pathology. Results One day and 1 week after RFA, renal lesions were wedge-shaped in the gross dissection cross-sectional profiles. Conventional ultrasound could not indicate the extent of the lesions; however, CEUS could exactly delineate the lesion shape and size. At 1 and 3 months, lesions were observed as hyperechogenic areas on conventional ultrasound, and as small perfusion defects on CEUS. The differences in the lesion measurements obtained by CEUS and in pathological specimens were not statistically significant (p > 0.05). Conclusions The conclusion could be deduced from the study that SonoVue-enhanced ultrasonography was effective for the follow-up of normal rabbit kidney percutaneous radiofrequency ablation.

A better way to manage perinephric abscesses: percutaneous ultrasonography-guided endoscopic lavage.  

PubMed

Purpose: To report the efficacy and safety of percutaneous ultrasonography-guided endoscopic lavage in the management of perinephric abscesses. Patients and Methods: This is a retrospective review of patients in a single center who had perinephric abscesses and were treated by percutaneous ultrasonography-guided endoscopic lavage during the period of March 2001 to March 2013. Information including the demographics, comorbid medical conditions, presenting symptoms, size of abscesses, operation information, and postoperative information were retrieved for review. Results: There were 37 patients (40 operations) identified during the study period. The mean age was 56.8 years (21-91 years). Eighteen (48.9%) patients presented with loin pain (48.6%) and/or fever (18, 48.6%), and the mean diameter of the abscesses was 10.8?cm (5-22?cm). Thirty-one (77.5%) procedures were performed under general anesthesia. The mean operative time was 49.4 minutes (15-140?min). Thirty-one (77.5%) patients had their percutaneous track dilated to 32F. Only two of 37 (5.4%) patients needed repeated drainage. The average postoperative drainage time was 8.35 days (3-21 days). The median postoperative hospital stay for our patients was 10 days (4-101 days). There was no mortality related to the abscess in this cohort. Conclusion: Percutaneous Ultrasonography-guided endoscopic lavage was shown to be an effective and safe approach for patients with perinephric abscesses. PMID:24372374

Contemporary technique of intraoperative 3-dimensional ultrasonography-guided transperineal prostate cryotherapy  

PubMed Central

Successful cryotherapy of the prostate for neoplasms relies on imaging to achieve good oncological outcomes with minimal complications. Traditional prostatic cryotherapy relies on 2-dimensional ultrasonography (2DUS) guidance, which often makes it difficult to track the passage of needles in an oblique plane. We describe our initial 3-dimensional ultrasonography (3DUS) system, and the subsequent improvements that have been made during the last 10 years. Our imaging system uses a Philips HDI 5000 ultrasonography unit, a standard PC, a Matrox Meteor II video frame grabber and 3DUS developed at Robarts Research Institute. For the cryotherapy we use ultrathin (17-gauge) IceRod needles. After image acquisition, preplanning is performed using the 3-dimensional (3D) software, and then the IceRod needles are inserted into the prostate. As the freezing process commences, continuous 3DUS images are taken and analyzed during the double freeze–thaw cycles to monitor the progress of the ice ball formation. Real-time intraoperative 3D imaging of the prostate during cryotherapy has allowed us to accurately preplan and then monitor the progression of ice ball formation, which represents a significant advantage over conventional 2DUS.

Comparison of Ultrasonography-Guided Central Venous Catheterization Between Adult and Pediatric Populations  

SciTech Connect

The purpose of this study was to compare the technical success and complication rates of ultrasonography-guided central venous catheterization between adult and pediatric patients which have not been reported previously. In a 4-year period, 859 ultrasonography-guided central vein catheterizations in 688 adult patients and 247 catheterizations in 156 pediatric patients were retrospectively evaluated. Mean age was 56.3 years (range, 18 to 95 years) for adults and 3.3 years (range, 0.1 to 16.3 years) for children. The preferred catheterization site was internal jugular vein in 97% of adults and 85% of children. The technical success rate, mean number of punctures, and rate of single wall puncture were 99.4%, 1.04 (range, 1-3), and 83% for adults and 90.3%, 1.25 (range, 1-5), and 49% for children, respectively. All the differences were statistically significant (p < 0.05). Complication rates were 2.3% and 2.4% for adults and children, respectively (p > 0.05). Major complications such as pneumothorax and hemothorax were not seen in any group. In conclusion, ultrasonography-guided central venous catheterization has a high technical success rate, lower puncture attempt rate, and higher single wall puncture rate in adults compared to children. Complication rates are comparable in the two groups.

Biomaterial implantation in facial esthetic diseases: ultrasonography monitor follow-up.  

PubMed

Facial deficit diseases are corrected by biomaterial implantation. The ideal biomaterial should be easy to implant and remove and simple to be identified by a low-dose radiation and low-cost radiologic technique. The purpose of this work was to evaluate ultrasonography (US) as a technique in monitoring biomaterial status after operation. In the last 3 years, for this study we used polyethylene porosus and polyacrylamide. Our study included 300 patients grouped accordingly as follows: malformative syndromes, degenerative syndromes, and esthetic problems, results of skull-facial traumas, and whether they are treated in the early phase and or the late phase. In this paper, we describe the better 15 clinical cases for their excellent result and for their variety of US images. Ultrasonography has been shown as an excellent way to visualize clinical features and a possible pathologic process of an implanted biomaterial; it is a noninvasive, low-radiation and low-cost dose radiologic technique. Reconstruction in facial deficit diseases needs adequate biomaterial to implant and a careful patients observation, that is, both clinical and radiologic. Ultrasonography is a fundamental component of the follow up of implanted biomaterial patients. PMID:18650740

IV-1?Accurate Targeting for LIPUS (Low Intensity Pulsed Ultrasound) Treatment with Ultrasonography.  

PubMed

The LIPUS device is self-administered by patients and the quantity and accuracy of daily treatment may be important for fracture healing. We characterized the quantity of treatment as the LIPUS compliance ratio. However, there remains doubt as to the accuracy of the targeting point. We typically indicate target points on the patients' skin, determined from radiograms taken over with clips near the surgical wound. Especially in the case of femoral fracture with thick soft tissue, it can be difficult to estimate accuracy of the treatment point. We used ultrasonography to visualize the fracture line clearly and to show the location of the treatment point. In most cases, we were able to visualize fractures easily and to demonstrate to patients how to use the transducer. The greatest advantage of ultrasonography is that we can inspect and estimate the fracture line with patients and thereby raise patient motivation. Targeting by ultrasonography is a simple and effective method that may improve both the quantity and the quality of LIPUS treatment. PMID:24854471

A case of poorly differentiated hepatocellular carcinoma with intriguing ultrasonography findings  

PubMed Central

A 60-year-old female was referred to the Toho University Omori Medical Center due to ultrasonography findings revealing a notable hepatic mass. The 44×32 mm isoechoic mass had a high-echo band along the margin in the liver. Contrast-enhanced ultrasonography (CEUS) with Sonazoid detected an enhancement pattern extending from the outer periphery to the inside of the mass in the vascular phase and a pattern similar to that of surrounding hepatic tissue in the post-vascular phase. High-flow hepatic hemangioma was suspected due to the hyperechoic rim-like high-echo band, the oval shape and the CEUS findings. However, computed tomography revealed a hypervascular hepatocellular carcinoma (HCC) pattern and the patient underwent surgery. Histopathological findings revealed poorly differentiated HCC. As poorly and moderately differentiated HCC types are conventionally classified as ‘hypervascular HCC’, few detailed ultrasonography (US) studies of poorly differentiated HCC are available. US characteristics of hypervascular HCC include the presence of a halo (hypoechoic band) around the lesion and reduced signal intensity in the post-vascular phase of CEUS. US in the patient revealed a mass with a hyperechoic band and a signal intensity in the post-vascular phase of CEUS that was almost identical to that of the surrounding liver parenchyma. These findings suggest poorly differentiated HCC and indicate that further research on hypervascular HCC is required.

Does ultrasonography accurately diagnose acute cholecystitis? Improving diagnostic accuracy based on a review at a regional hospital  

PubMed Central

Background Acute cholecystitis is one of the most common diseases requiring emergency surgery. Ultrasonography is an accurate test for cholelithiasis but has a high false-negative rate for acute cholecystitis. The Murphy sign and laboratory tests performed independently are also not particularly accurate. This study was designed to review the accuracy of ultrasonography for diagnosing acute cholecystitis in a regional hospital. Methods We studied all emergency cholecystectomies performed over a 1-year period. All imaging studies were reviewed by a single radiologist, and all pathology was reviewed by a single pathologist. The reviewers were blinded to each other’s results. Results A total of 107 patients required an emergency cholecystectomy in the study period; 83 of them underwent ultrasonography. Interradiologist agreement was 92% for ultrasonography. For cholelithiasis, ultrasonography had 100% sensitivity, 18% specificity, 81% positive predictive value (PPV) and 100% negative predictive value (NPV). For acute cholecystitis, it had 54% sensitivity, 81% specificity, 85% PPV and 47% NPV. All patients had chronic cholecystitis and 67% had acute cholecystitis on histology. When combined with positive Murphy sign and elevated neutrophil count, an ultrasound showing cholelithiasis or acute cholecystitis yielded a sensitivity of 74%, specificity of 62%, PPV of 80% and NPV of 53% for the diagnosis of acute cholecystitis. Conclusion Ultrasonography alone has a high rate of false-negative studies for acute cholecystitis. However, a higher rate of accurate diagnosis can be achieved using a triad of positive Murphy sign, elevated neutrophil count and an ultrasound showing cholelithiasis or cholecystitis.

Ultrasonography in the primary evaluation of patients with Perthes disease.  

PubMed

The utility of ultrasound in the primary examination of patients with Perthes disease was evaluated. Nineteen patients were examined with a longitudinal lateral and an anterior scan. Ultrasound was reliable in diagnosing Perthes disease when the surface of the ossified epiphysis was irregular and when fragmentation had occurred. There was good correspondence between ultrasound and radiography in assessment of femoral head coverage. Twelve patients had an increased anterior joint space, indicating accompanying synovitis. Femoral anteversion (AV) angles, measured by ultrasound, were significantly greater in the affected hips, but mean side difference (3 degrees) was moderate. Ultrasound provided useful information. Like conventional radiography, ultrasound showed the irregular structure of the bony epiphysis and the lateral coverage of the femoral head. In addition, the anterior coverage, an accompanying synovitis, and the degree of femoral AV were obtained. In the very early stage, the femoral head may look normal by ultrasound, but a persisting joint effusion arouses the suspicion of Perthes disease. PMID:8370776

Evaluation of gastrointestinal injury in blunt abdominal trauma "FAST is not reliable": the role of repeated ultrasonography  

PubMed Central

Background To determine the diagnostic Accuracy of Focused Assessment Sonography for Trauma (FAST) and repeated FAST in the patients with blunt abdominal trauma. Methods In this retrospective study we collected the data of all patients from September 2007 to July 2011 with gastrointestinal injury. The intraoperative outcome was compared with FAST technique and the repeated or delayed sonography. Results A total number of 1550 patients with blunt abdominal trauma underwent FAST in a period of 4 years in our hospital. Eighty-eight (5.67%) patients were found to have gastrointestinal injury after exploratory laparotomy. Fifty-five (62.5%) patients had isolated gastrointestinal injury and 33 (37.5%) patients had concomitant injury to the other solid organs. In those with isolated gastrointestinal injury, the sensitivity of FAST was 38.5%. Repeated ultrsonography was performed in 34 patients with false negative initial FAST after 12-24 hours. The sensitivity of repeated ultrasonography in negative initial FAST patients in detection of gastrointestinal injury was 85.2% (95% CI, 68.1%, and 94.4%). Conclusion Repeated sonography after 12 to 24 hours in patients with negative initial FAST but sustain abdominal symptom can facilitated a diagnosis of GI tract injury and can be as effective method instead of Computed tomography in developing country.

High resolution ultrasonography of the hand and wrist: three-year experience at a District General Hospital Trust.  

PubMed

A retrospective analysis of 227 patients undergoing ultrasonography (US) of the hand/wrist over a three-year period in a district general hospital trust was performed. The usefulness in each case was assessed by two independent reviewers using a qualitative rating system, as (A) Useful: determines management, (B) Useful: contributory, (C) Not useful: not misleading, or (D) Not useful: misleading/potentially harmful. US was useful in 74.8% of cases but misleading/potentially harmful in 13.1%. Misleading rates exceeding 10% in sub-categories including tendinopathy, carpal tunnel syndrome, foreign body and lumps, where US findings may influence the decision to operate or not, are particularly worrying. There were a number of cases where US led to unnecessary operations or suggested operating on the wrong structures, and also cases where US findings wrongly suggested that surgery was unnecessary. Various recommendations aimed to improve the usefulness of US in the Hand and Wrist, including mandatory/formal musculoskeletal US training, are made. PMID:21089192

Transcranial Doppler ultrasonography in the detection of venous to arterial shunting in acute stroke and transient ischaemic attacks.  

PubMed Central

OBJECTIVES: To prospectively evaluate the prevalence of venous to arterial shunting in patients with acute stroke and transient ischaemic attacks (TIAs) using transcranial Doppler ultrasonography (TCD) with saline contrast. METHODS: A consecutive series of patients with stroke or TIA underwent contrast TCD. Patients were subsequently divided into groups according to causative factors for stroke or TIA. The prevalence of right to left shunt was assessed within these groups. RESULTS: A total of 210 patients underwent contrast TCD. A right to left shunt was detected in 28.6% of patients (60 of 210). Among the patients with cryptogenic stroke or TIA, 37.1% (43 of 116) had a positive contrast TCD whereas only 18% (17 of 94) with another identifiable cause had a positive test (P = 0.0024). When age was used to further classify those patients with cryptogenic stroke, TCD was positive in 59.3% patients (16 of 27) of < or = 50 years of age versus 30.3% of patients (27 of 89) > 50 years of age (P = 0.0058). CONCLUSIONS: There was a significantly higher prevalence of venous to arterial shunting in patients with stroke or TIA of undetermined cause than in stroke patients with identifiable aetiologies, as detected by contrast TCD. The prevalence of a venous to arterial shunt was significantly higher in the younger group with cryptogenic stroke. Saline contrast TCD is a relatively non-invasive bedside procedure useful in the detection of venous to arterial shunting. Images

Automatic detection and measurement of femur length from fetal ultrasonography  

NASA Astrophysics Data System (ADS)

Femur bone length is used in the assessment of fetal development and in the prediction of gestational age (GA). In this paper, we present a completely automated two-step method for identifying fetal femur and measuring its length from 2D ultrasound images. The detection algorithm uses a normalized score premised on the distribution of anatomical shape, size and presentation of the femur bone in clinically acceptable scans. The measurement process utilizes a polynomial curve fitting technique to determine the end-points of the bone from a 1D profile that is most distal from the transducer surface. The method has been tested with manual measurements made on 90 third trimester femur images by two radiologists. The measurements made by the experts are strongly correlated (Pearson's coefficient = 0.95). Likewise, the algorithm estimate is strongly correlated with expert measurements (Pearson's coefficient = 0.92 and 0.94). Based on GA estimates and their bounds specified in Standard Obstetric Tables, the GA predictions from automated measurements are found to be within +/-2SD of GA estimates from both manual measurements in 89/90 cases and within +/-3SD in all 90 cases. The method presented in this paper can be adapted to perform automatic measurement of other fetal limbs.

[The role of ultrasonography and biopsy following kidney transplantation].  

PubMed

Several complications can occur during both the early and late postoperative periods after kidney transplantation. The methods used to follow up 575 kidney transplanted patients, (transplantations performed between October 1979 and November 1997) in the early (within 6 weeks) and late postoperative periods have been assessed. The diagnostic value of core biopsies and ultrasound examinations, the prevalence of complications, and the applicability of the diagnostic tools in the evaluation of the graft status and viability were analyzed. In the early postoperative period, graft rupture occurred more frequently after biopsy than in the late period (7.4% vs 0.82%), this leading graft loss in 18 of 20 cases. The sonographically diagnosed morphologic and functional changes were also analyzed. Sonography proved a very accurate method for the detection of perirenal fluid collections and masses and severe vascular complications. The data demonstrated that biopsy is indicated in the early postoperative period when the result of sonography is doubtful. In the late postoperative period, biopsy should be performed in every case.

Ultrasonography of the rumen in 30 Saanen goats.  

PubMed

This study describes the results of ultrasonographic examination of the rumen in 30 healthy Saanen goats. A linear or convex transducer with a variable frequency of 5 to 13 MHz was used to scan standing, non-sedated goats. The location and size of the rumen, the distance between the wall of the rumen and abdominal wall and the appearance and size of the gas, fibre mat and fluid layers of the ruminal contents were assessed. The rumen was seen as a large organ medial to the left abdominal wall. The wall of the rumen appeared as a thick echogenic line. The longitudinal groove was seen as an echogenic notch, which divided the rumen into the dorsal and ventral sacs. The rumen could be visualized from the 9th to 12th intercostal space (ICS) and flank on the left side in all the goats. The rumen was largest in the 12th ICS at 41.6 ± 5.13 cm and smallest in the 8th ICS at 11.3 ± 4.29 cm. The dorsal sac of the rumen was largest in the left cranial flank (17.4 ± 4.43 cm) and the ventral sac was largest in the 12th ICS on the left (29.1 ± 6.03 cm). In the cranial left flank, the rumen was situated immediately adjacent to the abdominal wall in all the goats. The spleen was located between the rumen and abdominal wall in the 8th to 12 th ICS in many of the goats. The gas, fibre mat and fluid layers of the ruminal contents could be visualized in all the goats. The gas layer was 9.9 ± 3.05 cm, the fibre mat layer 16.0 ± 4.55 cm and the fluid layer 12.2 ± 5.57 cm. PMID:21866512

Radiological assessment of vascular access in haemodialysis patients.  

PubMed

Clinical examination is still the most important diagnostic tool and duplex ultrasonography is the imaging method of first choice. Radiological assessment of vascular access for haemodialysis includes preoperative analysis of vessel anatomy and postoperative surveillance for access maturation as well as diagnosis in vascular access insufficiency. Compared to ultrasonography digital subtraction angiography is superior for the evaluation of the central veins and allows diagnosis and treatment in one session. Computed tomography should only be used in patients with inconclusive ultrasonography results, for example, for the assessment of the central veins and visualization of the vascular tree. Gadolinium-enhanced magnetic resonance imaging is no longer recommended in dialysis patients, because it may trigger nephrogenic systemic fibrosis. In patients with a history of previous central venous catheters additional preoperative imaging of the central veins should be performed. In this article we review the different radiological imaging methods for preoperative assessment and suspected vascular access dysfunction. PMID:24817452

Bifid scrotum and anocutaneous fistula associated with a perineal lipomatous tumor complicated by temporary bilateral cryptorchidism in utero mimicking ambiguous genitalia: 2-D/3-D fetal ultrasonography.  

PubMed

Ambiguous genitalia (AG) is a morphological diagnosis defined as genitalia not typical of a male or female. Findings mimicking AG, such as penoscrotal anomalies, anorectal malformations, and perineal lipomatous tumors, may prevent accurate identification of the fetal sex. We report a case of bifid scrotum and anocutaneous fistula associated with a perineal lipomatous tumor complicated by temporary bilateral cryptorchidism in utero, which were findings mimicking AG. Several perineal anomalies are associated developmental occurrences. In the present case, the combination of bifid scrotum and temporary bilateral cryptorchidism in the male fetus mimicked the combination of clitoromegaly and prominent labia, which are commonly observed in female fetuses. However, serial systemic assessments using prenatal 2-D/3-D ultrasonography and magnetic resonance imaging were unable to detect the anocutaneous fistula and differentiate the perineal lipomatous tumor. This case report suggests that the prenatal detection of perineal abnormalities may warn obstetricians of potentially undetected congenital perineal anomalies. PMID:24738127

Contrast-enhanced ultrasound (CEUS) continues to be in its infancy as it relates to evaluation of the acute abdomen. The purpose of this study was to compare survey radiography, B-mode ultrasound, CEUS, and CE-MDCT findings in canine patients presenting with acute abdominal signs; with a focus on the ability to differentiate surgical from non-surgical conditions. Nineteen dogs were prospectively enrolled. Inclusion required a clinical diagnosis of acute abdominal signs and confirmed surgical or non-surgical causes for the clinical signs. Agreement for the majority of recorded imaging features was at least moderate. There was poor agreement in the identification of pneumoperitoneum and in the comparison of pancreatic lesion dimensions for B-mode vs. CEUS. The CT feature of fat stranding was detected in cases including, but not limited to, gastric neoplasia with perforation, pancreatitis, and small intestinal foreign body. Ultrasound underestimated the size and number of specific lesions when compared with CE-MDCT. Contrast-enhanced ultrasound was successful in detecting bowel and pancreatic perfusion deficits that CE-MDCT failed to identify. Accuracy for differentiation of surgical vs. non-surgical conditions was high for all modalities; 100%, 94%, and 94% for CE-MDCT, ultrasonography and survey radiography respectively. Findings indicated that CE-MDCT is an accurate screening test for differentiating surgical from non-surgical acute abdominal conditions in dogs. Focused CEUS following CE-MDCT or B-mode ultrasonography may be beneficial for identifying potentially significant hypoperfused lesions. PMID:23919809

Low-intensity pulsed ultrasonography versus electrical stimulation for fracture healing: a systematic review and network meta-analysis  

PubMed Central

Background To best inform evidence-based patient care, it is often desirable to compare competing therapies. We performed a network meta-analysis to indirectly compare low intensity pulsed ultrasonography (LIPUS) with electrical stimulation (ESTIM) for fracture healing. Methods We searched the reference lists of recent reviews evaluating LIPUS and ESTIM that included studies published up to 2011 from 4 electronic databases. We updated the searches of all electronic databases up to April 2012. Eligible trials were those that included patients with a fresh fracture or an existing delayed union or nonunion who were randomized to LIPUS or ESTIM as well as a control group. Two pairs of reviewers, independently and in duplicate, screened titles and abstracts, reviewed the full text of potentially eligible articles, extracted data and assessed study quality. We used standard and network meta-analytic techniques to synthesize the data. Results Of the 27 eligible trials, 15 provided data for our analyses. In patients with a fresh fracture, there was a suggested benefit of LIPUS at 6 months (risk ratio [RR] 1.17, 95% confidence interval [CI] 0.97–1.41). In patients with an existing nonunion or delayed union, ESTIM had a suggested benefit over standard care on union rates at 3 months (RR 2.05, 95% CI 0.99–4.24). We found very low-quality evidence suggesting a potential benefit of LIPUS versus ESTIM in improving union rates at 6 months (RR 0.76, 95% CI 0.58–1.01) in fresh fracture populations. Conclusion To support our findings direct comparative trials with safeguards against bias assessing outcomes important to patients, such as functional recovery, are required.

Contribution of subcutaneous abdominal fat on ultrasonography to carotid atherosclerosis in patients with type 2 diabetes mellitus  

PubMed Central

Background Whereas visceral abdominal adipose tissue (VAT) is associated with cardiometabolic risk, there is debate regarding the role of subcutaneous abdominal adipose tissue (SAT). The aim of this study was to investigate the relationships of subcutaneous and visceral abdominal fat with carotid atherosclerosis in patients with type 2 diabetes mellitus (T2DM). Methods A total of 234 patients (men 131, women 103, mean age: 53 years) with T2DM were enrolled. Carotid intima-media thickness (CIMT), abdominal subcutaneous fat thickness (SFT) and visceral fat thickness (VFT) were assessed by high-resolution B-mode ultrasonography (US). Results Compared to women, men had significantly higher VFT and lower SFT (p?=?0.002, p?=?0.04, respectively). In partial correlation coefficient analyses between CIMT and abdominal fat thickness after adjustment for body mass index (BMI), SFT showed a negative correlation with CIMT in men (r?=?-0.27, p?=?0.03). VFT was not correlated with CIMT in either men or women. In women, SFT was not correlated with CIMT (r?=?-0.01, p?=?0.93). VFT/SFT ratio was not correlated with CIMT in either men or women. In multivariate regression analyses adjusted for BMI and other CVD risk factors, SFT but not VFT was independently inversely associated with CIMT in men but not in women (p?assessed by US was inversely associated with carotid atherosclerosis in patients with T2DM, particularly men. Further research into the different roles of the two types of abdominal adipose tissue in both men and women is warranted.

A critique of current practice of transvaginal pudendal nerve blocks: a prospective audit of understanding and clinical practice.  

PubMed

Pudendal nerve blocks are a pre-requisite to forceps delivery without regional anaesthesia. Their efficacy is dependent on introducing local anaesthetic in close proximity to the pudendal nerve and allowing sufficient time for its onset of action. An audit of 57 obstetricians evaluated their clinical technique against standards using both a questionnaire and adapted model pelvis. The majority of participants were unable to describe correctly the point of infiltration and were unaware of the lag time required to effect adequate analgesia. We identify a deficiency in training and describe a method by which training can be facilitated and assessed. PMID:23815197

Accuracy of ultrasonography in the diagnosis of acute calculous cholecystitis: review of the literature  

PubMed Central

Background To evaluate the accuracy of ultrasonography in the diagnosis of acute calculous cholecystitis in comparison with other imaging modalities. Methods The authors performed a search of the Medline/ PubMed (National Library of Medicine, Bethesda, Maryland) for original research and review publications examining the accuracy of ultrasonography in the diagnosis of acute calculous cholecystitis. The search design utilized a single or combination of the following terms : (1) acute cholecystitis, (2) ultrasonography, (3) computed tomography, (4) magnetic resonance cholangiopancreatography and (5) cholescintigraphy. This review was restricted to human studies and to English-language literature. Four authors reviewed all the titles and subsequent the abstract of 198 articles that appeared appropriate. Other articles were recognized by reviewing the reference lists of significant papers. Finally, the full text of 31 papers was reviewed. Results Sonography is still used as the initial imaging technique for evaluating patients with suspected acute calculous cholecystitis because of its high sensitivity at the detection of GB stones, its real-time character, and its speed and portability. Cholescintigraphy still has the highest sensitivity and specificity in patients who are suspected of having acute cholecystitis. However, due to a combination of reasons including logistic drawbacks, broad imaging capability and clinician referral pattern the use of cholescintigraphy is limited in clinical practice. CT is particularly useful for evaluating the many complications of acute calculous cholecystitis. The lack of widespread availability of MRI and the relatively high cost prohibits its primary use in patients with acute calculous cholecystitis. Conclusions US is currently considered the preferred initial imaging technique for patients who are clinically suspected of having acute calculous cholecystitis.

Automatic thickness estimation for skeletal muscle in ultrasonography: evaluation of two enhancement methods  

PubMed Central

Background Ultrasonography is a convenient technique to investigate muscle properties and has been widely used to look into muscle functions since it is non-invasive and real-time. Muscle thickness, a quantification which can effectively reflect the muscle activities during muscle contraction, is an important measure for musculoskeletal studies using ultrasonography. The traditional manual operation to read muscle thickness is subjective and time-consuming, therefore a number of studies have focused on the automatic estimation of muscle fascicle orientation and muscle thickness, to which the speckle noises in ultrasound images could be the major obstacle. There have been two popular methods proposed to enhance the hyperechoic regions over the speckles in ultrasonography, namely Gabor Filtering and Multiscale Vessel Enhancement Filtering (MVEF). Methods A study on gastrocnemius muscle is conducted to quantitatively evaluate whether and how these two methods could help the automatic estimation of the muscle thickness based on Revoting Hough Transform (RVHT). The muscle thickness results obtained from each of the two methods are compared with the results from manual measurement, respectively. Data from an aged subject with cerebral infarction is also studied. Results It’s shown in the experiments that, Gabor Filtering and MVEF can both enable RVHT to generate comparable results of muscle thickness to those by manual drawing (mean?±?SD, 1.45?±?0.48 and 1.38?±?0.56 mm respectively). However, the MVEF method requires much less computation than Gabor Filtering. Conclusions Both methods, as preprocessing procedure can enable RVHT the automatic estimation of muscle thickness and MVEF is believed to be a better choice for real-time applications.

Application of the Thyroid Imaging Reporting and Data System in thyroid ultrasonography interpretation by less experienced physicians  

PubMed Central

Purpose: To verify the usefulness of the Thyroid Imaging Reporting and Data System (TI-RADS) for thyroid nodule diagnosis by less experienced physicians. Methods: From March 2012 to May 2012, ultrasonography-guided fine needle aspiration was performed in 204 thyroid nodules in 195 consecutive patients by four less experienced radiologists (<1 year in thyroid imaging). The number of suspicious ultrasonography features and the total risk score of each thyroid nodule were calculated according to the previous two models suggested by Kwak et al. The Delong method was used to compare the areas under the curve (AUCs) of the two models. Associations between the two models and the risk of malignancy were analyzed using penalized B-splines and the Cochran-Armitage trend test. Results: Among 204 thyroid nodules, 65 were malignant and 139 were benign. The probability of malignancy tended to increase as the number of suspicious ultrasonography features, and the sum of risk scores increased. There was no significant difference in the AUCs of the two models (P=0.673). The Cochran-Armitage trend test demonstrated an increased risk of malignancy as the number of suspicious ultrasonography features and the total risk score increased (P=0.001). Conclusion: Both the number of suspicious ultrasonography features and the total risk score are applicable and show comparable results in the risk stratification of thyroid nodules by less experienced radiologists in thyroid imaging.

Complications of native arteriovenous fistula: the role of color Doppler ultrasonography.  

PubMed

Color Doppler ultrasonography (CDUS) is a readily available, inexpensive and noninvasive method, which has improved the survival of native arteriovenous fistula (AVF) by increasing the early diagnosis of complications. Although angiography has been currently considered as the gold standard for imaging of vascular access abnormalities, CDUS may be superior in some aspects, since it provides information both on the morphology and on the function of vascular access and it is the only tool directly available to the nephrologist. In addition, CDUS offers the advantage of a non-invasive bedside procedure with lower costs and with no need for radiocontrast. PMID:24720406

Prenatal diagnosis of congenital harlequin ichthyosis with 2D, 3D, and 4D ultrasonography.  

PubMed

Harlequin fetus is a rare and mostly fatal form of congenital ichthyosis that can be diagnosed by fetal skin biopsy in patients with a family history of the disease. More recently DNA analysis of amniocentesis and chorion villus sampling materials have also been utilized. We report a case of prenatally diagnosed congenital ichthyosis with no previous family history. Diagnosis was mainly achieved by 3D and 4D ultrasonography findings such as diffuse scaling of the skin, digital contractures, flattened rudimentary external ear, nasal hypoplasia, everted eyelids, typical fish mouth appearance, macroglossia, and persistently open fetal mouth.

Emergency department diagnosis of supraspinatus tendon calcification and shoulder impingement syndrome using bedside ultrasonography  

PubMed Central

A 45-year-old woman presented to the emergency department with a 2-day history of severe left shoulder pain made worse with movement. Emergency department (ED) bedside point-of-care static and dynamic ultrasound examination of the supraspinatus tendon revealed supraspinatus tendon calcification with impingement syndrome, and the patient was urgently referred to orthopedics after ED pain control was achieved. Bedside shoulder and supraspinatus tendon evaluation with static and dynamic ultrasonography can assist in the rapid diagnosis of supraspinatus tendon calcification and supraspinatus tendon impingement syndrome in the emergency department.

Image Analysis of Endosocopic Ultrasonography in Submucosal Tumor Using Fuzzy Inference  

PubMed Central

Endoscopists usually make a diagnosis in the submucosal tumor depending on the subjective evaluation about general images obtained by endoscopic ultrasonography. In this paper, we propose a method to extract areas of gastrointestinal stromal tumor (GIST) and lipoma automatically from the ultrasonic image to assist those specialists. We also propose an algorithm to differentiate GIST from non-GIST by fuzzy inference from such images after applying ROC curve with mean and standard deviation of brightness information. In experiments using real images that medical specialists use, we verify that our method is sufficiently helpful for such specialists for efficient classification of submucosal tumors.
