Quizplus · Accepted Answer

A bronchogram is an x-ray of the air passageways using a contrast medium, typically done to diagnose or monitor lung conditions such as pneumonia, bronchitis or lung cancer. Option A is a cholangiogram, which is a type of x-ray that uses contrast material to visualize the bile ducts in the liver. Option B is arthrography, which is an imaging technique used to visualize the inside of a joint (such as the knee or shoulder), often using contrast material to highlight the structures. Option C, photofluorography, is a type of x-ray imaging that involves creating a "moving" image of various organs or structures within the body, typically done to evaluate motion or the function of organs such as the esophagus or diaphragm.
