[Technetium 99m-diphosphate as an imaging agent in acute myocardial infarction (author's transl)].
To test the sensitivity and specificity of 99m-Technetium-Diphosphat myocardial scintigraphy in the diagnosis of acute myocardial infarction we examined the scintigrams of 53 patients admitted to our CCU. In all 38 patients with transmural myocardial infarction positive scintigrams with localized uptake of the tracer found. Myocardial imaging was performed 70--90 minutes after the intravenous injection of 15 mCi 99m-Technetium-Diphosphat in anterior and LAO position. The clinical value of the method for proving the presence or absence of a myocardial infarction is demonstrated on infarctions combined with bundle-branch block, pacemaker Ecg and on reinfarction. All normal cases in this group showed no tracer activity outside the bones. In unstable angina pectoris a faint but not localized tracer activity was found.
