Multiple Gated Acquisition Scan (MUGA)
The Multiple Gated Acquisition (MUGA) scan is a noninvasive test to evaluate the pumping function of the heart. It produces a moving image of the beating heart’s chambers.
What to Expect During a MUGA Scan
After undressing from the waist up, you will be given a gown and asked to lie on an exam table under a gamma camera. Electrodes will be attached to your chest for an electrocardiograph (EKG) monitor, which helps with the interpretation of the electrical activity of your heart. An IV line will be placed in your arm in order to inject a radioactive material that will be picked up by the camera.
Moving images of your beating heart will be displayed on a video monitor in order to measure how well your heart pumps with each beat.
How to Prepare for a MUGA Scan
There is no preparation for a MUGA Scan. Please consult your physician about any medications you may take before the test.
