A MUGA scan is a nuclear imaging test which is designed to evaluate the function of the heart. This test may give Dr. Diego a good depiction of how well the patient’s heart is pumping blood.
MUGA, which stands for Multi-Gated Acquisition, is used to measure the function of the heart, and whether the heart valves and chambers are working efficiently. It’s also called Radionuclide Angiography or Radionuclide Ventriculography.
A MUGA scan may help Dr. Diego diagnose problems in patients who are having chest pains, difficulty breathing, dizziness, or fatigue. This scan may be used if other tests such as the echocardiogram or EKG indicate a heart problem. If the heart isn’t pumping enough blood to meet the needs of the body, it fits the definition of heart failure.
During a MUGA scan, a small amount of a radioactive substance called a tracer is injected into the bloodstream. The tracer, which attaches to red blood cells, is photographed by a special camera. This allows the doctor to visualize blood inside the working chambers (ventricles) of the heart.
