(medicine)
Roentgenography of the bile ducts.

Cholangiography

 

roentgenographic examination of the gallbladder and bile ducts after the introduction (orally or intravenously) of an iodine-containing contrast agent that is excreted with bile. The procedure is not applied in the case of pronounced jaundice. Cholangiography yields a clear picture of the anatomical structure and functioning of the gallbladder and bile ducts; it reveals the presence of calculi, or gallstones (cholelithiasis), inflammatory changes (cholecystitis or cholangitis), and disruption of the emptying mechanism of the bladder (dyskinesia).

In some BA cases, operative cholangiography may show a patent lower common bile duct in continuity with the gallbladder, with the atretic process restricted to the common hepatic and hepatic ducts.
