MUGA Scan

MUGA scan (Multigated acquisition) or Gated scan.

Purpose of a MUGA scan:

A MUGA scan is used to assess a patient’s heart function. This test is often performed before a patient starts a type of chemotherapy regimen that contains drugs associated with potential side effects to heart such. These drugs include doxorubicin (adriamycin), herceptin, epirubicin (the risk is lower than doxorubicin), and others.

What is a MUGA scan?:

MUGA scan uses the electrical signals of the heart to trigger the camera to take a series of pictures that can be viewed later like a motion picture. The pictures record the heart's motion and determine if it is pumping (contracting) properly. MUGA scanning may take 2 to 3 hours to obtain all the needed views and can be done both before and after you exercise. You may be given nitroglycerin to see how your heart responds to this medicine. MUGA scanning may be done after a first-pass scan. It is usually not done on children.
