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).

Given that serum IgG4 concentrations nor cholangiographic or cholangioscopic features do not differentiate these disorders clearly (32-34), endoscopic biopsy is often required to differentiate IgG4-related sclerosing cholangitis from both primary sclerosing cholangitis and hilar cholangiocarcinoma.

Pathological Features.--Primary sclerosing cholangitis involves large bile ducts, and cholangiographic findings of large-duct damage form the mainstay of diagnosis.
