Abstract
201Tl scintimetry of the heart was used for a statistical comparison between normal people (10 individuals) and those with acute anterior wall infarcts (5 patients), anterior wall hypokinesia (5 patients) and dyskinesia (8 patients). Numerical results were obtained by a computer and depended on the relative 201tl storage in the left ventricular myocardium (64 mm2 area) related to mediastinal background uptake. It was found that maximal myocardial uptake, compared with mediastinal activity (about 290%) did not differ between normals and patients with coronary heart disease. Aneurysms of the anterior ventricular wall showed a reduction (with the ventricle perpendicular to the collimator) of 45.8%; in hypokinesia and acute myocardial infarcts, it was 64.2% and 64.6% respectively (normal 82.6%). 201Tl uptake in aneurysms (42.4%) approached background activity (36%) if a projection parallel to the collimator was used. 201Tl scintimetry provides a means of defining functional ability of the myocardium (depdending on myocardial perfusion and mass). Aneurysms and hypokinetic portions of the myocardium can be differentiated statistically from normal 201Tl uptake.
