Simultaneous detection of myocardial perfusion and wall motion abnormalities by cinematic 201Tl imaging

A method for simultaneous acquisition of static and ECG-synchronized 201Tl myocardial images is reported. The ECG-synchronized images are then displayed continuously in cinematic format. In studies of 37 patients, the cinematic technique provided detection of regional wall motion abnormalities and improved distinction of cardiac borders without losing perception of perfusion defects. Cinematic display is a useful addition to 201Tl myocardial imaging.
