Multigated Acquisition Scan


What do I need to know about a multigated acquisition scan?

A multigated acquisition (MUGA) scan is a test used to examine the chambers and blood vessels of your heart. It shows how well the left ventricle of your heart is pumping. Healthcare providers will be able to measure the ejection fraction (the amount of blood that pumps out of your heart with each heartbeat).

How do I prepare for a MUGA scan?

Your healthcare provider will talk to you about how to prepare for the test. He may tell you not to eat or drink for several hours before your test. He will tell you what medicines to take or not take on the day of your test.

How is a MUGA scan performed?

Your healthcare provider will place an IV into a vein, usually in your hand or arm. He will inject a substance called radioactive tracer to make blood that pumps through your heart show up better. You will also have electrodes placed on your chest to have an EKG. An EKG will record your heart rhythm and how fast your heart beats. A camera will be placed over your heart to take pictures. Healthcare providers may repeat the test after you exercise or after they give you medicine to stress your heart.

What are the risks of a MUGA scan?

You may have bleeding, redness, or swelling where the IV was placed. The test may increase your risk for an irregular heart rate or a heart attack.
