Nadolol, a recently developed noncardioselective beta-adrenergic blocker, has the potential advantages of a longer oral half-life (t 1/2) than propranolol and, in animal studies, markedly fewer direct myocardial depressant effects. Neither the relati

The left ventricular ejection fraction was determined serially with radioisotope angiography in 63 patients with acute myocardial infarction. After the peripheral injection of a bolus of technetium-99m, precordial radioactivity was recorded with a ga

Accurate glomerular filtration rates (GFR) can be calculated based on the infusion of small amounts of nonradioactive iothalamate and collection of plasma samples for assay by x-ray fluorescence. This innovation permits frequent clearance determinati

We have recently reported on the relationship between left ventricular (LV) volume (V) determined by contrast ventriculography (CV) and corresponding volume units calculated from LV region-of-interest counts obtained from ECG gated equilibrium radion

Because of the high target-to-background contrast obtained with single photon emission computed tomography (SPECT), normal intrahepatic vessels approximately 2 cm in diameter may appear as distinct focal defects in tomographic sections throughout the

During the past several years and in cooperation with our cardiology colleagues, we have attempted to perfect a method of determining left-ventricular ejection fraction that can be applied in the evaluation of patients with left-ventricular dysfuncti

The accurate measurement of cardiac chamber volume is of major importance in assessing cardiac performance. Accurate equilibrium radionuclide volume estimations are difficult to obtain, due to the geometry of the chambers, and the physical characteri

Seventy-six patients were studied within one week of contrast ventriculography to assess the influence of differing background assignments on ejection fractions derived from gated equilibrium radionuclide anigograms. "Fixed" and "variable" left-ventr
