Myocardial localization of 99mTc-pyrophosphate without evidence of acute myocardial infarction.
Localization of 99mTc-pyrophosphate in the cardiac region during routine bone scanning for metastatic tumor is discussed in two cases. Clinical information as well as electrocardiographic and serum enzyme studies did not reveal any evidence of acute myocardial injury. The cause of myocardial localization of the radiopharmaceutical is not clear in these cases.
