In recent years technological advancements in nuclear medicine have resulted in increasing interest in the use of radioisotope techniques in the evaluation of cardiac disease, and cardiovascular nuclear medicine has developed into a useful noninvasive tool in clinical cardiology. Myocardial infarct imaging with technetium-99m pyrophosphate has been demonstrated to be a reliable method in the diagnosis of suspected myocardial infarction. Radioisotope cardiac flow studies are useful in the diagnosis and follow-up of congenital heart disease, and gated cardiac blood pool imaging is emerging as an important technique in the evaluation of left ventricular function and ejection fraction. One of the more promising recent applications of nuclear medicine in cardiology has been the development of myocardial perfusion imaging in the evaluation of coronary artery disease. Thallium 201 is the major radioisotope employed in myocardial perfusion imaging and this report will review its basic properties and its use in the diagnosis of ischemic heart disease.
