Abstract

Abnormal left ventricular function is a diagnostic indication of cardiac disease. Left ventricular function is commonly quantified by ejection fraction measurements. A novel approach for the determination of left ventricular ejection fraction from technetium-99m-methoxy isobutyl isonitrile multiple-gated radionuclide angiocardiography is presented. Data from 23 patients, symptomatic of cardiac disease, indicate that ejection fractions determined using the radionuclide technique correlate well with contrast X-ray single-plane cineangiography (r=0.83, p<10^-6). Data from 14 of the patients indicate favorable correlation with technetium-99m-pertechnetate gated blood pool radionuclide angiocardiography (r=0.87, p<10^-4)
