Myocardial perfusion scintigraphy with thallous chloride T1 201 shows a 'cold spot' of decreased uptake in areas of reduced blood flow. The major application of this technique is, of course, in detecting coronary artery disease, but it has also proved useful in diagnosis of acute myocardial infarcts, congenital heart disease, and other myocardial diseases and in follow-up after coronary revascularization. More specific in detecting myocardial infarcts, however, is technetium Tc 99m pyrophosphate myocardial imaging, which shows 'hot spots' of increased uptake in areas of necrosis.
