A bone scan is a nuclear imaging test that helps diagnose and track several types of bone disease. Your doctor may order a bone scan if you have unexplained skeletal pain suggesting bone loss, bone infection or a bone injury undetectable on a standard X-ray.
A bone scan is also an important tool for detecting cancer that has spread (metastasized) to the bone from a tumor that started in a different organ, such as the breast or prostate. Similarly, a bone scan can detect some abnormalities related to leukemia and lymphoma.
