Muga Scan


A multigated acquisition (MUGA) scan is a test used to examine the lower chambers of your heart (ventricles). It shows how well the ventricles pump blood. Healthcare providers will measure the amount of blood that pumps out of your heart with each heartbeat. You may have this test while you are at rest, with exercise, or both.


Contact your healthcare provider if:

  • You have pain, redness, or swelling in the area where the tracer was injected.
  • You have questions or concerns about your condition or care.


  • Drink plenty of water to help flush the tracer out of your body. The tracer leaves your body within a few days through your urine or bowel movements. Ask your healthcare provider how much liquid to drink each day and which liquids are best for you.
  • Wash your hands well with soap and water each time you urinate.

Follow up with your healthcare provider as directed:

You may need to return to go over the results of your tests. Write down your questions so you remember to ask them during your visits.
