There are at least four types 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.

# [[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) is another cholangiography method.
