'''Cholangiography''' is the imaging of the [[bile duct]] (also known as the biliary tree) by [[x-rays]] and an injection of contrast medium.<ref>{{Cite web|title=Cholangiography {{!}} Gallbladder cancer {{!}} Cancer Research UK|url=https://www.cancerresearchuk.org/about-cancer/gallbladder-cancer/getting-diagnosed/tests-diagnose/cholangiography|access-date=2021-01-04|website=www.cancerresearchuk.org}}</ref>

==Types==

There are at least twofour kindstypes of cholangiography:{{cn|date=January 2022}}

*# [[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.

In both cases [[fluorescent]] fluids are used to create contrasts that make the diagnosis possible. Cholangiography has largely replaced the previously used method of [[intravenous cholangiography]] (IVC).{{cn|date=January 2022}}

* [[Magnetic resonance cholangiopancreatography]] (MRCP) and [[T tube cholangiography]] areis otheranother cholangiography methodsmethod.
