Bone Scan
A bone scan is a diagnostic exam that evaluates the bones for new areas of growth or breakage. It may be used for the entire body or just a certain area, and can diagnose a specific problem. A bone scan can often detect abnormalities much earlier than a regular X-ray.
During a bone scan, a radioactive tracer substance is injected into a vein in the arm and helps show cell activity and function of the bones as it travels through them. A special camera can capture images of the tracer to help identify any abnormalities. The procedure takes about an hour and is generally painless.
A bone scan can help diagnose bone fractures or chronic, unexplained bone pain.
