The efficacy of thallium 201, 99mTc phosphates, and 99mTc MAA in localizing small myocardial infarctions in the pig

MR Tetalman, LC Foley, CP Spencer and SP Bishop

An intercomparison was made of technetium phosphates, thallium 201, and technetium-labeled MAA to define areas of small myocardial infarction in pigs. Byinstilling 0.01 ml of mercury into the coronary arteries, 2- cm infarcts were created. Several of the infarcts were in the anterior left ventricular wall. None of the infarcts was imaged with 99mTc phosphates. Three of the seven thallium 201 images demonstrated only diffuse right ventricular activity. Three of the seven infarcts were imaged with technetium MAA; a perfusion defect was seen in the area of infarction. Technetium MAA is the most sensitive agent in defining areas of abnormal myocardial perfusion.
