AbstractNuclear medicine plays an integral role in the management of differentiated thyroid cancer. This editorial aims to provide a summary of the current role of radionuclide imaging, including whole body iodine scan and fluorodeoxyglucose (FDG)-positron emission tomography (PET), in the diagnostic work-up and follow-up of patients with thyroid cancer.

Nine cases of suspected craniotomy flap osteomyelitis evaluated by combined bone and gallium scanning are presented. In six cases, the clinical data were inconclusive and evaluation by radionuclide imaging provided an accurate negative diagnosis. The other three cases considered positive by this technique were proven infected at subsequent exploration and ...

False-positive radionuclide liver images can occur due to impingement on the liver by adjacent normal anatomic structures or adjacent pathologic masses or fluid collections. A patient with ascites in the anterior subphrenic space had an apparent cold lesion in the left lobe of the liver. Ultrasonography demonstrated a normal left lobe and localized the ...

From multiple single-pinhole exposures of a three dimensional object, taken with a position-sensitive gamma-ray detector, tomographic images of radionuclide distribution in patients during diagnostic tests are formed with the aid of a computer. The effect...

Significant effort currently is being devoted to the development of noninvasive imaging systems that allow in vivo assessment of biological and biomolecular interactions in mice and other small animals. While physiological function in small animals can be...

Abundantly illustrated with material culled from the McGill University Hospitals, the text examines the pathophysiology and the clinical manifestations of the disease entities in detail. The radionuclide modality is examined for its strengths and weaknesses and its place in the diagnostic algorithm is suggested for many of the entities in view of other competing or ...

Sequential computerized hepatobiliary imaging was performed in 11 jaundiced patients before, during, and after biliary decompression. The rates of plasma clearances and radionuclide accumulation in liver cells and biliary tree were calculated, in addition to the uptake and retention index.

Forty-three papers discuss methods for improvement of the images from radionuclide scans and radiographs for diagnostic purposes. Abstracts of three papers have appeared previously in ERA.

Two geriatic male rhesus monkeys were used for the radioisotope imaging in this research. Discussion of the radionuclide, materials and method used to accomplish the neurologic examination and the results obtained, both during the procedure and confirmati...

This paper describes new strategies for the brain-specific delivery of radionuclides that can be used to evaluate regional cerebral perfusion by single photon imaging techniques. A description of several examples of interesting new strategies that have re...

Although myocardial imaging is currently dominated by Tl-201, several alternative agents with improved physiologic or radionuclidic properties have been proposed. Based on human and animal studies in the literature, the metabolism of several of these comp...

Recent clinical evaluations of scintimammography (radionuclide breast imaging) are promising and suggest that this modality may prove a valuable complement to X-ray mammography and traditional breast cancer detection and diagnosis techniques. Scintimammog...

This book discussed embryology, anatomy, physiology, and immunology of the small intestine. Radiographic procedures in the small intestine especially enterolysis are presented. Focus is on the role of other types of imaging techniques including sonography, computed tomography, radionuclide imaging, angiography, biopsy, and enteroscopy.

The purpose of this study was to compare CT and radionuclide imaging of osmotic blood-brain barrier disruption, and to develop a quantitative method for imaging osmotic blood-brain barrier disruption and to see if iopamidol could be safety given intravenously in conjunction with blood-brain barrier disruption. Forty-five blood-brain ...

An unexpected vesicocolic fistula can be detected incidentally on routine bone scintigraphy. A 55-year-old man who had a radical colectomy for carcinoma of the sigmoid colon 1 year previously underwent bone scintigraphy to evaluate bone metastasis. Whole-body images showed an abnormal accumulation of radioactivity in the right lower quadrant of the abdomen, but the ...

Radionuclide brain imaging, a simple, noninvasive test for evaluating patients with suspected cerebral pathology, has a high degree of accuracy when compared with more complex neuroradiologic procedures such as angiography and pneumoencephalography. The detection of brain tumors with use of radionuclide scans is related to the tumor ...

Two geriatic male rhesus monkeys were used for the radioisotope imaging in this research. Discussion of the radionuclide, materials, and method used to accomplish the neurologic examination and the results obtained, both during the procedure and confirmation of the results by necropsies were accompanied by color photos of scan images. ...

The ECAT was designed and developed as a complete computerized positron radionuclide imaging system capable of providing high contrast, high resolution, quantitative images in 2 dimensional and tomographic formats. Flexibility, in its various image mode options, allows it to be used for a wide variety of ...
