[Results of myocardial perfusion scintigraphy (author's transl)]

Myocardial perfusion scintigraphy by means of the microsphere technique is a valuable method for detecting regional myocardial scars. The use of the microsphere technique is indicated in all patients who have had myocardial infarction and before coronary bypass operations. In a certain group of patients with severe but atypical angina pectoris and a normal coronary arteriogram and in some arrhythmias the perfusion scintigram can provide information on changes coronary microcirculation. The assessment of myocardial blood flow redistribution under pharmacological intervention is a further indication for the microsphere technique.
