Having intuitively validated the concept of Wu et a!., let us review our experience with the red-
bean flow to learn principles of indicator dilution in a pulsatile bean model, which might be …

Cardiovascular Performance In 1971, the technique of gated cardiac blood-pool imaging
was developed. In this approach, the electrocardiogram is introduced into the imaging …

Radionuclide angiography techniques have been used for the noninvasive evaluation of
ventricular performance since the late seventies. These techniques require peripheral …

SUMMARY (ABSTRACT) A method for radioisotope angiocardiography using the
scintillation camera arid a quantitative television data system for rapid data recording and …

Materials and Methods Twelve patients, age 27-67 (mean 51) years were studied. Three
patients had valvular heart disease, and 9 patients had symptomatic coronary artery …

Changes in ejection fraction (EF) and segmental wall motion (SWM) have been shown to be
sensitive indicators of left ventricular (LV) function. This information is only obtainable by …

Sequential quantitative first pass radionuclide angiocardiograms (RA) were used to
measure left ventricular ejec-tion fraction (LVEF) and left ventricular ejection rate (LVER) …

Quantitative analysis of 201T1images has been proposed as a method of improving the
detection and localization of myocardial isehemia (18). Unfortunately, computer programs …
