MUGA Scan (Multigated Acquisition Scan)
A MUGA scan is a nuclear scan that evaluates the heart’s pumping function.
A camera will be focused on your heart to analyze the amount of radio-labeled red blood cells pumped out of the heart with each heartbeat. This is called the ejection fraction.
Preparation
To prepare, wear comfortable clothes that can easily be removed. There is a consent form for this procedure.
Procedure
During the test you will be asked to lie on a table under a large camera. Your heart will be monitored on an ECG (electrocardiograph) monitor and you will receive IV radioactive tracer material.
This test is not associated with any pain or discomfort. The MUGA scan takes about one to two hours to perform.
