A MUGA scan, which stands for “multiple gated acquisition,” is a nuclear-medicine test that allows your doctor to see if your heart is beating properly.

In a MUGA scan, a radioactive substance called Technetium 99 is is injected into the bloodstream. This substance attaches to red blood cells, and it can be viewed through the body using a special camera that ultimately produces a moving image of the beating heart.

A MUGA scan allows your doctor to measure how much blood is pumped by the heart with each heart beat. This measurement, called the left ventricular ejection fraction (LVEF) is a good measurement of overall heart function.
