[Scanning of the myocardium with pyrophosphate-technetium 99m. 367 cases].
Pyrophosphate-99m Tc injected intravenously is almost invariably fixed in the infarcted zone in transmural infarctions less than 8 days old. Fixation occurs in only 2/3 of cases of rudimentary infarction. The degree of fixation is more or less proportional to the size of the peak of creatine phosphokinase. After the 8th day following infarction, fixation is slight or nil. It is inconstant in pre-infarction syndrome or simple angina. This examination complements clinical, electrocardiographic and enzyme findings, in particular in the case of difficult diagnosis.
