Which imaging test involves X-ray examination of the bile ducts with a contrast medium?

• A. Cholangiography
• B. Angiography
• C. Cholecystography
• D. Hysterosalpingography

Answer: (A)

Cholangiography is the imaging test that uses X-rays to visualize the biliary ducts after injecting a radiopaque contrast medium. This contrast fills the bile ducts—the hepatic ducts, common hepatic duct, common bile duct, and intrahepatic ducts—so they appear on X-ray or fluoroscopy. This helps identify stones, blockages, strictures, or leaks in the biliary system. The other options target different structures: angiography images blood vessels; cholecystography focuses on the gallbladder itself; hysterosalpingography images the uterus and fallopian tubes.
