Abstract
Resting computerized transaxial tomography was performed after i.v. injection of 201Tl in 6 normal subjects and 5 patients who had had myocardial infarctions 3 mo. to 4 yr previously. Decreased myocardial activity corresponded to the site of previous infarction in all cases and was clearly separated from adjacent myocardium with normal activity. With tomography, the left ventricle was clearly separated from surrounding structures such as the left-ventricular cavity, the lungs and the liver. The feasibility for assessment of myocardial perfusion using single-photon transaxial emission computed tomography was demonstrated.
