A HIDA, or biliary, scan is a test that uses a radioactive substance (or tracer) to examine the liver, gallbladder and bile ducts in detail. The radiation you are exposed to with the injected radioactive substance is about the same as a regular x-ray. A HIDA scan is performed to detect abnormalities in the biliary system, such as inflammation of the gallbladder, abnormal gallbladder contractility, bile duct obstruction or liver disease. HIDA scans depict functional information that is not visible on routine x-ray or ultrasound examinations.
