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.

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.
The biliary tree (see below) is the whole network of various sized ducts branching through the liver.. The path is as follows: bile canaliculi → canals of Hering → interlobular bile ducts → intrahepatic bile ducts → left and right hepatic ducts merge to form → common hepatic duct exits liver and joins → cystic duct (from gall bladder) forming → common bile duct → joins with ...
Endoscopic retrograde cholangiography may be useful to visualize the extrahepatic biliary ducts. [87] In case of anatomical anomalies, or if endoscopic retrograde cholangiography is unsuccessful, percutaneous transhepatic cholangiography may be used. [77]
He was qualified with the title of Docent in Radiology in 1967 after successfully defending his thesis on percutaneous transhepatic cholangiography. [2] He was later able to demonstrate, using "phantom experiments", how one could insert a catheter into the femoral artery and reach both the parathyroid and renal arteries.
