Myocardial perfusion scintigraphy is a non-invasive technique to evaluate myocardial perfusion and ventricular function. It is used to detect functional abnormalities of the coronary arteries, myocardial scar, and ventricular function; and to stratify cardiac risk. A radioactive tracer is administered intravenously, usually during exercise which can be dynamic (treadmill) or pharmacological. The distribution of the tracer within the myocardium is imaged using a gamma camera, the degree of uptake of tracer representing a combination of myocardial viability and perfusion. Further images after a resting injection of tracer are usually obtained to distinguish between defects caused by scan and inducible perfusion defects.
