Non-Invasive Cardiology Diagnostic Procedures

Multi Gated Blood Pool Nuclear Exams (MUGA)

What is it?  A MUGA scan is a test that examines how well your heart is pumping by tagging and tracking red blood cells as they circulate through a number of cardiac cycles.

What happens during the test?  An IV is started so that a radioactive substance called technetium can be sent through your bloodstream.  This substance will tag the red blood cells so that they can be identified throughout the test.  A special camera will count these cells as they travel through numerous cardiac cycles, and it will generate images of your heart chambers and the larger blood vessels that lead to and from it.

Preparing for the Test:

  • You may take all of your daily medications.
  • You may eat and drink as usual.
  • Wear comfortable clothes. Please don’t wear a top with metal snaps or zippers.
  • You will be able to drive yourself home following the test.

Helpful Information:

  • Please arrive 15 minutes prior to your scheduled time.
  • Bring your insurance cards and current list of medications with doses and frequency.
  • You will be here for approximately 1.5 – 2 hours. An IV will be started for a blood draw and injection. Images will be taken following the injection.
  • If you must cancel the test, please call the location you are scheduled, 24 hours in advance.
