Which term denotes a diagnostic imaging procedure used to visualize a joint by recording images?

• A. Arthrocentesis
• B. Arthrodesis
• C. Arthroscopy
• D. Arthrography

Answer: (D)

Imaging the joint by recording images is arthrography. This procedure injects contrast into the joint and then uses X-ray imaging (often fluoroscopy) to visualize the joint space and internal structures, helping identify tears, cartilage defects, or ligament injuries. The other terms refer to different actions: arthrocentesis withdraws joint fluid for analysis, arthrodesis surgically fuses a joint, and arthroscopy uses a camera to directly view the inside of a joint, usually as a surgical or diagnostic procedure rather than an imaging study that records radiographic images.
