Thallium-201 scintigraphy of the exercised myocardium was performed in 70 male patients admitted for coronary arteriography and left-ventricular angiography. Left ventricular scintigrams were collected in left lateral, left anterior oblique (65/sup 0/, 45/sup 0/, and 25/sup 0/), and anterior views, and the images were divided into eight segments: apical, anteroseptal, anterior, anterolateral, posterolateral, posterior, inferior, and posteroseptal. A correlative study between segmental hypoperfusion on scintigram and coronary-artery stenosis visualized by contrast arteriography allowed selection of specific segments for each main coronary artery. Coronary-artery disease could be detected in 95 percent of patients having more than 50 percent coronary-artery stenosis, with 93 percent specificity. In most cases, patients with two-vessel disease and three-vessel disease could not be distinguished from each other. Multiple-vessel disease suggested by segmental analysis of myocardial scintigrams after exercise was confirmed arteriographically in 88 percent of the patients, but 52 percent with scintigrams suggesting single-vessel disease had, in fact, multiple-vessel disease.
