Application of radionuclide imaging in the detection of acute myocardial infarction
Radionuclide imaging was useful for noninvasively visualizing a location and size of infarction in two patients with acute myocardial infarction. In one patient, inferior subendocardial myocardial infarction was detected by 99mTc-PYP myocardial scintigraphy and then inferior transmural infarction was observed as more intense radioactivity with a larger size. In the other patient with acute extensive anterior myocardial infarction, akinesis of the left ventricular wall and left ventricular aneurysm were confirmed by first-pass radionuclide angiocardiography and multigated equilibrium cardiac pool scan.
