What is rest MUGA?
A rest multiple-gated acquisition (MUGA) is a simple test to show how well your heart is pumping blood. A special camera takes pictures at specific times during each heartbeat.
Why is your doctor ordering MUGA?
MUGA helps your doctor see how well your heart is pumping to learn why you may be having chest pain, trouble breathing, dizziness or tiredness. MUGA can also track the effect of certain chemotherapy drugs on the heart.
What to expect
During your MUGA, an intravenous line (IV) will be started in your arm through which you will receive medication to prepare your red blood cells. You will then receive a small amount of radioactive tracer so you heart can be seen with a special camera. One 5-minute picture will be taken of your heart while you lie on your back. The test takes about an hour.
