As in most other nuclear medicine facilities, tomographic myocardial imaging was started here with the patients in the supine position. However, previous planar imaging experience indicated a high number of false-positive results using the supine pos

1.1. During A-V dissociation there is a tendency for atria and ventricles to contract synchronously or almost synchronously. 2.2. Five examples of A-V dissociation manifesting this tendency to synchronize are presented. 3.3. Graded criteria for suspe

An area of relatively increased tracer activity on a perfusion lung scan was found in the same location as a radiodense lung mass. The lesion responsible for this unusual combination of findings was identified after lobectomy and tissue examination t

✓ In a retrospective study of 44 patients with verified ruptured intracranial aneurysms, the results of radionuclide cerebral perfusion scintigraphy (dynamic brain scanning) and the presence or absence of arteriographic spasm were correlated with t

Forty-five patients with subarachnoid hemorrhage due to verified intracranial aneurysms were studied prospectively to determine whether delaying operations in those patients with abnormal cerebral perfusion, assessed by radionuclide dynamic scanning,

An extensive clinical evaluation was undertaken to assess the value of myocardial infarct imaging with radioactive potassium and analogues. Of 130 patients so examined, 80 were diagnosed as having suffered infarcts in the recent or distant past on th

The usefulness of digital phantoms and computer simulation of the scanning process to evaluate computer methods for improving the presentation of scan data is demonstrated. Knowledge of the exact radioactivity distribution, i.e. the digital phantom,

A device for simple, rapid, and accurate extrapolation of directly recorded dye- or isotope-dilution curves has been described and evaluated. A set of exponential curves was constructed to serve as an underlay for rectilinear recordings of dilution c

Tachycardia and peripheral vasoconstriction are the usual means by which the cardiovascular system, under nervous control, attempts to compensate for a lowering of pressure in the systemic arteries. When such compensatory efforts are absent during su
