Which term describes a visual record of a joint?

• A. Myelogram
• B. Serum Calcium
• C. Splint
• D. Arthrogram

Answer: (D)

A joint imaging study that uses injected contrast to outline the joint structures creates a visual record of the joint. This is called an arthrogram. By infusing contrast into the joint space, an arthrogram makes the cartilage, ligaments, and joint capsule more visible on X-ray, fluoroscopy, or CT, helping to detect tears or other abnormalities that aren’t easily seen on standard images. The other terms refer to different things: a myelogram images the spinal canal with contrast, not a joint; serum calcium is a blood test for calcium levels; a splint is a device to immobilize a limb or joint.
