MUGA Scans at ZP

A multigated acquisition (MUGA) scan is a non-invasive diagnostic test used to evaluate the pumping function of the lower chambers of the heart and shows how well your heart pumps blood. During this test, a small amount of radioactive tracer is injected into a vein and a special camera, called a gamma camera, detects the radiation released by the tracer to produce computer-generated video images of the beating heart. A MUGA scan is a highly accurate test that is used to determine the heart’s pumping function. To schedule an appointment, or to learn more about MUGA scans at ZP, then contact our office today!

How to Prepare for the Test

When you schedule your scan, you will perceive detailed instructions on how to prepare. You may not be able to eat or drink for four to six hours before your test, and you may be asked to avoid caffeine and tobacco for up to 24 hours before the test. When you go into our imaging center to complete the procedure, it is recommended that you wear comfortable clothes that can be easily removed, as you may be asked to wear a hospital gown during the test. Before beginning, be prepared to discuss some aspects of your medical history, your allergies, and any concerns you have about the test.

During the Test

A technologist will attach electrodes to the skin of your chest. Men may have their chest hair shaved to allow for a better connection. These electrodes are then attached to an electrocardiograph monitor (EKG) that charts your heart’s electrical activity during the test.

Then, an IV will be inserted into a vein in your arm where a radioactive tracer will be injected into your blood. This tracer tags your red blood cells so that they can be detected by the camera.

For a resting scan, you will lie on a table with a special camera above it. The camera will take many pictures of your heart while it is resting.

For an exercise scan, you will be asked to walk on a treadmill or ride a stationary bike until you reach your peak activity level. Then, you will stop and again lie on a table while the gamma camera takes pictures of your heart.

The test will take between one and two hours. Once you have completed the test, it is recommended that you drink plenty of water to flush the radioactive tracer from your body.

After the exam, your preferred physician will have access to the results and will contact you to discuss them.
