nuclear imaging for heart disease
MUGA (Multiple Gated Acquisition) Scan. Also called radionuclide angiography (RNA), this non-invasive test is used to evaluate the function of the heart ventricles. It measures how much blood is pumped out per heartbeat. A radioactive tracer solution attaches to red blood cells, which are visualized by a special camera and translated on a computer as they travel through the heart. This test is more accurate than an echocardiogram.
