MUGA scan

MUGA - Multiple Gated Acquisition scan is a non-invasive diagnostic tool that is used to assess the heart's functioning with moving images. MUGA scan uses a radioactive substance Technetium 99. It is injected to the patient's bloodstream where it is attaches to red blood cells. A gamma camera is used to detect low-level radiation given off by these red blood cells. The MUGA scan helps in determining the condition of the heart and its functioning of the cardiac ventricles.

This nuclear heart scan follows the movement of the technetium through the blood. Images are recorded for later analysis. An important pointer to the cardiac efficiency is the LVEF (Left Ventricular Ejection Fraction). The MUGA scan is preferred over other diagnostic tests such as echocardiogram as it is highly accurate and non-invasive. MUGA scan is also called cardiac blood pool imagine or equilibrium radionuclide angiography. Sometimes stress MUGA scan and rest MUGA scan are taken and analyzed. This is best done under the guidance of a cardiologist. MUGA scan aids in checking a person's heart function after chemotherapy.
