Blood supply of the myocardium during rest or under stress is examined with this test. It is examined whether there is an obstruction or not in the vessels supplying heart and if there is, whether this obstruction creates a dysfunction of the supplying of heart or not. It is a more sensitive test than stress effort test. First, the patient is given intravenous radioactive material and resting images are obtained in the device called gamma camera, then the patient is walked on the treadmill or stress test with medication is performed, again radioactive agent is injected. Images are obtained in gamma camera again. Radioactive material reaches to heart and myocardium. This material is less involved at the places where there is atherosclerosis.
Gama camera is the name of the device provides taking images. It turns around the heart with certain periods and transmits the radioactive signals from the heart to a computer. The computer transforms the obtained signals to a colored image and performs the blood supply analysis of the all regions of the heart. In which cases myocardium perfusion scintigarphy is requested; In the determination of the chest pains relationship with heart disease, in the diagnosis of cardiovascular diseases, determination of the vitality of myocardium after myocardial infarction, in the determination of the procedure’s benefit and necessity before and after coronary balloon angioplasty, as a disease screening test in patients who have risk factors of cardiovascular diseases, detecting the importance of the vascular disease in people with cardiovascular disease, detecting the effectiveness of treatment after coronary bypass surgery or medical treatment, to detect whether the patients had or not myocardial infarction and for the determination of the wideness and severity of the myocardial infarction
