Feedback:
An arthrogram is a radiographic examination of a joint, usually the knee or shoulder. The physician first injects a local anesthetic and then inserts a needle into the joint space. Fluoroscopy may be used to verify correct placement of the needle. The synovial fluid in the joint is aspirated and sent to the laboratory for analysis. A contrast medium is then injected, and x-ray films are taken. Arthroscopy is the internal inspection of a joint using an instrument called an arthroscope. Arthrocentesis is the aspiration of synovial fluid. The client receives local anesthesia just before this procedure. The physician inserts a large needle into the joint and removes the fluid. This can be done during an arthrogram or arthroscopy. Bone densitometry estimates bone density using radiography or advanced radiographic techniques.
