Bone and/or joint imaging; whole body

AI EXPLANATION: A whole-body bone scan is a specialized nuclear imaging test used to evaluate the entire skeleton. During the test, a small, safe amount of a radioactive tracer is injected into a vein and travels through the bloodstream. As the tracer is absorbed by the skeleton, a special camera scans the body to create detailed images that highlight areas of unusually high or low bone activity, helping clinicians detect bone conditions such as fractures, arthritis, infections, or unexplained bone pain.
