A MUGA scan, which stands for Multigated Acquisition Scan, is a non-invasive medical imaging procedure used to evaluate the functioning of the heart. This particular scan focuses on the heart's chambers, primarily assessing how well they are pumping blood. This procedure is extremely beneficial as it provides essential information about the health of your heart.

MUGA scan employs a radioactive tracer and a special camera to produce images of your heart as it beats. These images are then utilized to create a movie which showcases the chambers of the heart contracting and subsequently pumping blood. Doctors usually recommend a MUGA scan to gauge the heart's pumping function, particularly the left ventricle's functioning, as it supplies the body with oxygenated blood. People undergoing chemotherapy, those with heart conditions, or individuals experiencing symptoms such as shortness of breath, fatigue, or chest pain may be advised to have a MUGA scan.
