MultiGated Blood-Pool Imaging Scan

What is the doctor looking for?

A MUGA scan (MultiGated blood-pool imaging scan) is a test that examines how well your heart is pumping.

What is the test?

The test is also known as a multigated graft acquisition, cardiac blood-pool imaging, and equilibrium radionuclide angiocardiography. A MUGA scan uses a special substance that “tags” red blood cells so they can be identified. A special camera then counts these cells during numerous cardiac cycles, and generates an image of your heart chambers and the larger blood vessels leading to and from it. First, you will be placed on a table and a technician will begin an intravenous (IV) line. This allows technetium, a radioactive substance which helps “tag” the red blood cells, to be sent through your bloodstream. You are then hooked to an ECG monitor, and asked to lie very still. The technician and physician will use a special camera to view images of your heart on a screen, and store them on a computer for later interpretation.

Where are the tests done?

A MUGA scan is performed in a hospital, with a technician and physician present.
