What Happens During a Muga Scan Procedure?

Muga scan ProcedureThe muga scan, or multigated acquisition test, is a procedure where the chambers of the heart are scanned. The scan shows if the heart pumps are functioning properly. This test can also reveal any existing abnormalities in the size and function of one’s heart.

What to Expect During Testing

Your doctor will provide you with instructions on how to prepare for the examination. Here is a short list of what you can expect during your muga scan.

  1. You will be instructed to remove all articles of jewelry and accessories, as these items could interfere with your scan and results. You may also be instructed to change into a hospital gown.
  2. Electrodes will be placed on your chest and a harmless tracer dye will be injected intravenously to monitor your heart’s activity during the test. You will need to lie still for some or all of the procedure in order for the test to be administered properly.
  3. As the dye diffuses through your blood, it will bind to the red blood cells, allowing one to see how the blood is flowing to and from your heart. A small medical camera will snap pictures of your heart’s activity from many different angles.

After the muga scan, you may be instructed to drink lots of water and fluids to help flush the radioactive dye from your system. Your doctor may also have special instructions for you to follow.

This test is used to assess your heart function and determine which method(s) of treatment will help you to obtain optimal heart health. To learn more about the testing process or to make an appointment, call Brookhaven Heart at 631-654-3278.
