Myocardial Perfusion

A Myocardial Perfusion Scan images the blood supply (perfusion) to the heart muscle using a gamma camera. The blood supply is made visible to the camera by the introduction of a small amount of radioactive tracer (radiopharmaceutical or MIBI) injected into an arm vein.  Occasionally an alternative tracer called Thallium is used. Depending on the exact heart condition in question, the procedure may be performed at rest, with the heart under stress or, most commonly, both.

Myocardial scans give information useful in diagnosing and managing conditions such as coronary artery disease, dead tissue resulting from a lack of blood supply (infarcts) and diseases of the heart muscle (cardiomyopathy).
