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 .

Oral cholecystography is a radiological procedure used to visualize the gallbladder and biliary channels, developed in 1924 by American surgeons Evarts Ambrose Graham and Warren Henry Cole.
Percutaneous transhepatic cholangiography, percutaneous hepatic cholangiogram (PTHC) is a radiological technique used to visualize the anatomy of the biliary tract. [1] A contrast medium is injected into a bile duct in the liver, after which X-rays are taken.
Endoscopic retrograde cholangiopancreatography (ERCP) is a technique that combines the use of endoscopy and fluoroscopy to diagnose and treat certain problems of the biliary or pancreatic ductal systems.
There are at least four types of cholangiography: [citation needed] Percutaneous transhepatic cholangiography (PTC): Examination of liver and bile ducts by x-rays. This is accomplished by the insertion of a thin needle into the liver carrying a contrast medium to help to see blockage in liver and bile ducts.
MRCP has been slowly replacing endoscopic retrograde cholangiopancreatography (ERCP) as investigation of choice. MRCP is highly accurate in diagnosing the biliary system, pancreatic duct and accessing surrounding solid organs.
Non-contact thermography, thermographic imaging, or medical thermology is the field of thermography that uses infrared images of the human skin to assist in the diagnosis and treatment of medical conditions.
