Myocardial Perfusion Imaging:
A diagnostic study which uses a small amount of radioactive tracer injected into the body and a small camera that detects the radiation to produce a computer image of the heart. Combined with exercise, the study can help determine if there is adequate blood flow to the heart at rest, as compared with activity.
Multigated Acquisition Scan (MUGA scan):
A nuclear scan that evaluates the pumping function of the ventricles.
