A cholescintigraphy scan, also known as: hepatobiliary iminodiacetic acid (HIDA), paraisopropyl iminodiacetic acid (PIPIDA), or diisopropyl iminodiacetic acid (DISIDA) scan is a nuclear imaging procedure to evaluate the health and function of the gallbladder. A radioactive tracer is injected through any accessible vein, then allowed to circulate to the liver, where it is excreted into the biliary system and stored by the gallbladder and biliary system.
