'''Cholangiography''' is the imaging of the [[bile duct]] (also known as the biliary tree) by [[x-rays]] and an injection of contrast medium.

==Types==

There are at least twofour kindstypes 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.

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).

[[Magnetic resonance cholangiopancreatography]] (MRCP) andis [[T tube cholangiography]] are otheranother cholangiography methodsmethod.
