Thallium-201 exercise myocardial perfusion scintigraphy, a new, non-invasive screening method, serves to visualize stress-induced ischemic regions and scarred tissue. As compared to the exercise electrocardiogram, the method shows higher sensitivity and specificity in detecting coronary artery disease. Moreover, it makes it possible to localize the predominant defects. Even though myocardial scintigraphy cannot replace coronary arteriography in establishing the precise morphologic situation of the coronary arteries, it is of help in deciding whether an arteriogram should be carried out or not. Thus, important indications for myocardial stress scintigraphy are atypical chest pain and an abnormal electrocardiogram without pain. Furthermore, the method is useful for evaluating patients with uninterpretable electrocardiograms during exercise, and in assessing the outcome of coronary artery bypass surgery.

D011877 Radionuclide Imaging The production of an image obtained by cameras that detect the radioactive emissions of an injected radionuclide as it has distributed differentially throughout tissues in the body. The image obtained from a moving detector is called a scan, while the image obtained from a stationary camera device is called a scintiphotograph.

D003327 Coronary Disease An imbalance between myocardial functional requirements and the capacity of the CORONARY VESSELS to supply sufficient blood flow. It is a form of MYOCARDIAL ISCHEMIA (insufficient blood supply to the heart muscle) caused by a decreased capacity of the coronary vessels.
