If you mean a HIDA: scan it involves injection of a radiotracer that is taken up by the bile/biliary system and then taking xray pictures to watch the dye flow. From this information, a radiologist can tell if the GB is squeezing normally and if there is evidence of inflammation or blockage of normal flow. It is commonly used to diagnose biliary dyskinesia or to rule out cholecystitis in an acute setting. Good luck!
