An X-ray examination of the bile ducts and gall bladder, after a special contrast medium has been injected.
Process of recording biliary duct function with x-rays.
An X-ray study of the gallbladder and ducts often done in the course of surgery of the gallbladder and related structures.
X-ray examination of the bile ducts, used to demonstrate the site and nature of any obstruction to the ducts or to show the presence of stones within them. A dye that is opaque to X-rays is introduced into the ducts either by injection into the bloodstream (intravenous cholangiography); direct injection into the liver (percutaneous transhepatic cholangiography); direct injection into the bile ducts at operation (operative cholangiography); or by injection into the duodenal opening of the common bile duct through an endoscope (endoscopic retrograde cholangiopancreatography, ERCP).
The process whereby the bile ducts and the gall-bladder are rendered radio-opaque and therefore visible on an X-ray film.
A diagnostic procedure involving the utilization of a distinct dye injected into the bile ducts, followed by radiographic examination. This method serves to ascertain the condition of the bile ducts, specifically detecting any signs of enlargement, constriction, or obstruction.
A diagnostic imaging technique employs the utilization of a contrast medium, a substance that is resistant to X-rays, to enhance the visibility of the bile ducts on X-ray images. This procedure aids in the diagnosis of biliary stones, which resemble gallstones but form within the bile ducts rather than the gallbladder, as well as the identification of narrowings or tumors within the bile ducts. However, this procedure is gradually being supplanted by ultrasound scanning and magnetic resonance imaging (MRI), both of which offer the ability to locate stones and provide detailed imaging without the need for contrast medium.
