Computed tomography angiography (CTA) is today a well-established diagnostic technique for non-invasive vascular imaging and has replaced diagnostic intra-arterial angiography. Especially since the implementation of multi detector-row computed tomography (MDCT) the acquisition of isotropic data sets is possible, thus widening the spectrum of clinical ...

Duodenal varices are a rare complication in patients with portal hypertension. Bleeding from duodenal varices often results in a severe prognosis. Diagnosis of the disease is usually based on findings obtained by endoscopy or angiography. However, it occasionally fails to detect the lesion and demonstrate its porto-systemic shunt vessels which are necessary information to decide an appropriate ...
OBJECTIVE: Patients with type 2 diabetes mellitus (T2DM) are at risk of polyvascular comorbidities and poor prognosis. Non-invasive techniques for early prediction of coronary artery disease (CAD) are desirable to prevent cardiovascular events in these patients. The aim of the present study was to investigate the association between CAD and systemic arteriosclerosis by qualitative vascular ...
The ileocecal area is a relatively short segment of the gastrointestinal tract but may be affected by pathologic conditions that are either common throughout the gastrointestinal system or exclusive to this area. These conditions include benign and malignant tumors, inflammatory processes (appendicitis, diverticulitis, epiploic appendagitis, Crohn disease), infectious diseases, and miscellaneous ...
The ability to diagnose pancreatic carcinoma has been rapidly improving with the recent advances in diagnostic techniques such as contrast-enhanced Doppler ultrasound (US), helical computed tomography (CT), enhanced magnetic resonance imaging (MRI), and endoscopic US (EUS). Each technique has advantages and limitations, making the selection of the proper diagnostic technique, in terms of purpose ...
Micropigs are the most likely source animals for xenotransplantation. However, an appropriate method for evaluating the lung of micropigs had not been established. Therefore, this study was performed to evaluate the feasibility of 64-channel multi-detector row computed tomography (MDCT) to measure the diameter of the pulmonary arteries and the lung volume ...

A wide spectrum of common and uncommon diffuse liver diseases affecting neonatal and pediatric liver transplant candidates is presented and analyzed using 16 and 64 multi-detector row helical CT (MDCT) and 1.5 T MRI fast imaging. Correlation of imaging findings and explanted liver or histology is illustrated in representative cases. Associated uncommon ...
The purpose was to evaluate a relationship between slice thickness and calculated volume on CT liver volumetry by comparing the results for images with various slice thicknesses including three-dimensional images. Twenty adult potential liver donors (12 men, 8 women; mean age, 39 years; range, 24-64) underwent CT with a 64-section multi-detector row CT ...

Fox), associated with the bats Myotis lcifuigus (Le Conte) and Tadarida ...
ObjectiveTo evaluate the spectrum, prevalence, and significance of incidental non-cardiac findings (INCF) in patients referred for a non-invasive coronary angiography using a 128-slice multi-detector CT (MDCT).Materials and MethodsThe study subjects included 1,044 patients; 774 males (mean age, 59.9 years) and 270 females (mean age, 63 years), referred for a coronary CT ...
BACKGROUND: Multi-detector computed tomography (MDCT) has been used to provide diagnostic information after heart valve replacements such as prosthetic valve dysfunction. However, only few data are available about aortic paraprosthetic regurgitation (APR). The aim of this study is to assess the feasibility, accuracy, and reproducibility of the existence of APR using ...
The most recommendable MRI sequence for the morphologic assessment of the cartilage damage due to osteoarthritis (OA) is gradient echo fat suppression T1 weighted image (SPGR: Spoiled gradient recalled acquisition in the steady state, FLASH: Fast low-angle shot). For the detection of the cartilage degeneration before the morphological change, T2 mapping, dGEMRIC (delayed Gd-DTPA2-Enhanced MRI of ...
A 57-year-old man presented with renovascular hypertension with chronic kidney disease. 16-Multi-detector row computed tomography (MDCT) showed that the left renal artery was totally occluded and the left kidney was atrophied. The left atrophied kidney was hormonally active despite the desolation of glomerular filtration function. Percutaneous renal ...
Catheter-directed digital subtraction angiography (DSA) is considered the standard for evaluation of superficial temporal to middle cerebral artery (STA-MCA) bypass patency. Few clinical investigations have been performed that evaluate the efficacy of computed tomographic angiography (CTA) in the assessment of extracranial-intracranial bypass. Using multi-detector ...
Multi-detector computed tomography (MDCT) scanner is available in most hospitals and is increasingly being used as the first line imaging in trauma and suspected cardiovascular emergencies, such as acute coronary syndrome, pulmonary artery thrombo-embolism, abdominal aortic aneurysm and acute haemorrhage (Ryan et al. Clin Radiol 60:599-607, 2005). A ...

The purpose of this study was to determine the optimal tube current setting and scanning mode for hominid fossil skull scanning, using multi-detector row computed tomography (CT). Four fossil skulls (La Ferrassie 1, Abri Pataud 1, CroMagnon 2 and Cro-Magnon 3) were examined by using the CT scanner LightSpeed 16 (General Electric Medical Systems) with ...
The shortage of organ donors has stimulated interest in the possibility of using animal organs for transplantation into humans. In addition, pigs are now considered to be the most likely source animals for human xenotransplantation because of their advantages over non-human primates. However, the appropriate standard values for estimations of the liver of micropigs have not been established. The ...
