Final answer:
ERCP is the procedure used to visualize the cystic, hepatic, and common ducts. A tube is placed down the throat, into the stomach, and then into the small intestine to inject dye and allow for visualization of the ducts on an X-ray.
Step-by-step explanation:
The procedure used to visualize the cystic, hepatic, and common ducts is Endoscopic Retrograde Cholangiopancreatography (ERCP). In an ERCP, a healthcare professional places a tube down the throat, into the stomach, then into the small intestine. Dye is used to help the doctor see the structure of the common bile duct, other bile ducts, and the pancreatic duct on an X-ray.
