What is a MUGA scan?

A multigated acquisition scan (also called equilibrium radionuclide angiogram or blood pool scan) is a noninvasive diagnostic test used to evaluate the pumping function of the ventricles (lower chambers of the heart). During the test, a small amount of radioactive tracer is injected into a vein. A special camera, called a gamma camera, detects the radiation released by the tracer to produce computer-generated movie images of the beating heart. The MUGA scan is a highly accurate test used to determine the heart’s pumping function.

How should I prepare for the test?

  • There is no special preparation required for this test; there are no medication or food restrictions.
  • Wear comfortable clothes that can be easily removed, as you may be asked to wear a hospital gown during the test.
