Which term is the process of recording pictures of a joint?

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

Answer: (C)

Recording pictures of a joint involves imaging to visualize its internal structures. The term combines arthro- meaning joint with -graphy meaning recording or imaging. In arthrography, contrast dye is often injected into the joint to outline the joint space, ligaments, and cartilage so that X-ray, CT, or MRI can clearly show abnormalities. This is different from other procedures: drawing fluid from a joint is arthrocentesis, surgically fusing a joint is arthrodesis, and replacing a joint is arthroplasty. Therefore, the term for recording pictures of a joint is arthrography.
