Résumé : Myocardial scintigraphy using Thallium 201 shows up most myocardial infarctions at the acute or subacute stage. However, it does not enable acute infarctions to be distinguished from established necrosis or ischemia. If, in a second phase, a tracer such as pyrophosphate marked with Technetium 99m, (which is more specific for recent necrosis) is used, a fairly complete list of myocardial lesions can be drawn up and very accurate information about their position can be given. Linked with the exercise test, myocardial scintigraphy using Thallium 201 has been found to be more sensitive and more specific than the usual exercise electrocardiogram for showing coronary insufficiency. It is, therefore, an excellent method for detecting coronary disease and, at the same time, provides physiological information which supplements the morphological findings obtained by coronarography.
