A MUGA (multigated acquisition) scan is a scan of your heart and blood flow. This type of scan shows how well your heart pumps blood to the rest of your body.
During this test, a small amount of a radioactive substance called a tracer is injected into one of your veins. A camera detects the tracer as it flows through your heart.
The camera takes a series of pictures of your heart. Each picture is taken at a specific time of the heartbeat. The pictures are strung together so that they look like a video of your heart's motion and the blood moving through it.
A MUGA scan is done to check the size of the chambers of the heart and how well your heart muscle pumps blood to the rest of the body.
The test may take about 1 to 2 hours.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse call line if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
