Cholangiography is the imaging of the bile duct (also known as the biliary tree) by x-rays and an injection of contrast medium. __TOC__
==Types== There are at least four types of cholangiography: 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. Endoscopic retrograde cholangiopancreatography (ERCP). Although this is a form of imaging, it is both diagnostic and therapeutic, and is often classified with surgeries rather than with imaging. Primary cholangiography (or perioperative): Done in the operation room during a biliary drainage intervention. Secondary cholangiography: Done after a biliary drainage intervention.
