In the evaluation of myocardial perfusion, or blood flow through the coronary arteries, the SPECT scan may require both a resting and a stress test. The stress test is performed either by treadmill exercise or with medication if the patient cannot walk on the treadmill. The cardiac SPECT scan can identify areas of the heart which do not receive adequate blood flow during stress, called ischemia, as well as find areas of irreversibly damaged heart, or scar.
