A hepatobiliary iminodiacetic acid (HIDA) scan is an imaging procedure that shows how well your liver, bile ducts and gallbladder are functioning. It can help diagnose certain conditions, such as cholecystitis, biliary leak and biliary atresia.
During a HIDA scan, a camera takes pictures of your gallbladder after a radioactive tracer is injected into a vein in your arm. The tracer travels through your liver, gallbladder, bile ducts, and small intestine. The camera takes a series of pictures of the tracer as it moves along.
