Diagnosis may or may not be determined by an ultrasound, but most likely the disease and other<unk>  diseases of the liver, gallbladder, and bile duct are found by what is most commonly referred to as a hepatobiliary or HIDA scan. This type of imaging is known as cholescintigraphy. Cholescintigraphy Cholescintigraphy or hepatobiliary scintigraphy is scintigraphy of the hepatobiliary tract, including the gallbladder and bile ducts. The image produced by this type of medical imaging, called a cholescintigram, is also known by other names depending on which radiotracer is used, such as HIDA scan, PIPIDA scan, DISIDA scan, or BrIDA scan. Cholescintigraphic scanning is a nuclear medicine procedure to evaluate the health and function of the gallbladder and<unk>  system. A radioactive tracer is injected through any accessible vein and then allowed to circulate to the liver and starts accumulating in the gall bladder which can take up to an hour. A standard fatty meal (usually a high fat milk shake) is then given and more imaging is performed for another hour so that the response to the fatty meal by the gall bladder can be shown. The gall bladder should respond and begin emptying into the duodenum, the amount of bile ejected can then be calculated as an ejection fraction (EF). An EF < 35% is considered to be diagnostic of<unk>  and suitable for cholecystectomy to be considered.
