Intravenous cholangiography

Intravenous cholangiography is the injection of a contrast agent into the body from the vein. The liver can excrete this contrast agent into the biliary tract through the bile, and the contrast agent discharged into the biliary tract can develop the bile duct without the need to concentrate the gallbladder. Therefore, this is an examination method mainly used to diagnose bile duct disease. The current commonly used biliary contrast agent is called bile glucosamine.
