Cholangiography: Definition, Uses, and Clinical Overview
Cholangiography is an imaging technique used to visualize the bile ducts. It usually involves filling the biliary tree with contrast material and taking images, often with fluoroscopy (real-time X-ray). Clinicians use it to evaluate blockage, narrowing, leaks, or abnormal anatomy in the hepatobiliary system. It is commonly used in endoscopy suites, interventional radiology, and operating rooms.
