What term refers to a radiographic examination of the bile ducts?

The term that refers to a radiographic examination of the bile ducts is cholangiography. This medical procedure involves the use of imaging techniques to visualize the bile ducts, which are important structures that transport bile from the liver and gallbladder to the intestine. In cholangiography, a contrast dye is injected into the bile ducts, allowing them to be seen more clearly on X-rays. This process is crucial for diagnosing issues such as blockages, stones, or tumors within the biliary system.

Other options do not pertain to the examination of bile ducts. For instance, bronchopneumonia relates to an infection in the lungs, while cephalothoracopagus is a term used to describe a rare condition in conjoined twins where the heads and thoraxes are joined. Chlamydia, on the other hand, is a sexually transmitted infection and is unrelated to radiographic examinations. Understanding these distinctions highlights the importance of specialized terms in medical contexts.
