Diagnosis of coronary artery disease with 201Tl. Computer analysis of myocardial perfusion images

JW Fletcher, KE Walter, KF Witztum, JL Daly, FK Herbig, HS Mueller and RM Donati

The diagnostic sensitivity of visually interpreted and computer- analyzed 201Tl myocardial perfusion images was compared to that of exercise electrocardiograms in 8 angiographically normal subjects and 24 patients with significant coronary artery disease. Visual interpretation was not significantly better than exercise ECGs. An index of perfusion homogeneity, derived from computer analysis of the 201Tl images, was more sensitive than visual interpretation (79% vs. 58%) and much more sensitive (p less than 0.05) than the exercise ECG (79% VS. 46%). The best overall sensitivity (88%) and specificity (75%) were achieved by combining computer analysis with exercise electrocardiography. The computer also permits enhanced detection of subtle perfusion changes which may not seem significant to the eye.
