Percutaneous transhepatic cholangiography, also called percutaneous hepatic cholangiogram and abbreviated PTHC, is a radiological technique used to visualize the anatomy of the biliary tract. A contrast medium is injected into a bile duct within the liver and X-rays are then taken, and the technique provides access to the biliary tree when endoscopic retrograde cholangiopancreatography has been unsuccessful. It was first reported in 1937 and became a popular technique by 1952.
