This study aimed to characterize cerebral perfusion in men with Klinefelter's syndrome, known to present specific deficits in language, using (99m)Tc- hexamethylpropylene-amine-oxime scintigraphy and Talairach normalization. While a perfusion asymmetry toward the left hemisphere was found in controls, perfusion was mostly symmetrical in Klinefelter patients in the upper temporal and lower parie...

Vaskov, L. S. (1973). British Journal of Industrial Medicine, 30, 3741. Use of radioisotopes in the study of textile workers with byssinosis and chronic lung damage. A radioisotope method of measuring separately the circulation times for the pulmonary artery and pulmonary veins is described. Combined with pulmonary scintigraphy this method has been used to invesigate textile workers with lung c...

Most large or fatal pulmonary embolisms (PE) at autopsy were unsuspected ante mortem. Newly identified clinical characteristics of PE enhance our ability to identify potential patients. Because of laudable efforts to diagnose PE, about 90% of outpatient computed tomographic (CT) angiograms are negative. Overuse of CT angiography has resulted in huge expenses and exposure of many to radiation. A...

Living-donor lobar lung transplantation (LDLLT) is indicated for rapidly deteriorating patients, and the total volume of two lower lobe grafts must be sufficient for the recipient. To rescue patients with small lobar grafts, we performed five LDLLTs sparing native upper lobes. This strategy was used when upper lobes or segments were preoperatively less impaired. There were no hospital deaths. E...

Although thallium-201 exercise scintigraphy has been established for the detection of myocardial ischemia and viability, little is known regarding the myocardial thallium-201 kinetics during angioplasty. Herein, we report a 77-year old man with angina pectoris, in whom serial myocardial imaging after a single dose of thallium-201 was helpful in identifying not only the culprit lesion and myocar...

BACKGROUND Pre-operative evaluation of lung cancer patients relies on calculation of predicted post-operative (PPO) lung function based on split lung function testing. Pulmonary perfusion (Q) PET/CT can now be performed by substituting Technetium-99 m labeling of macroaggregated albumin (MAA) with Gallium-68. This study compares Q PET/CT with current recommended methods of pre-operative lung fu...

UNLABELLED Lung volume reduction (LVR) is an effective therapy for end-stage emphysema. Preliminary and postprocedure imaging is usually limited to CT for anatomic delineation of the location and severity of the most acutely affected lung zones. The purpose of this study was to investigate the potential of using a new quantitative gas trapping index (GTI) derived from a (133)Xe ventilation scan...

UNLABELLED The use of a so-called gestalt interpretation, an integration of different sets of criteria and the physician's own experience, has been advocated in the interpretation of lung scintigraphs of patients with clinically suspected pulmonary embolism. However, data on the reliability of this approach are limited. The aim of this study was to investigate the observer variability and accur...
