In an emergency situation like a stroke, it's important for doctors to first confirm the type of stroke to provide the appropriate treatment. Imaging tests like a CT scan or MRI can help determine the type of stroke; blood flow tests like cerebral angiography, can help evaluate the size and location of blockages.
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.
