Bone scintigraphy, also known as a bone scan, is a nuclear imaging technique used to evaluate bone metabolism and detect abnormalities in the bones. This diagnostic procedure involves the intravenous injection of a small amount of radioactive material (radiopharmaceutical) that tends to accumulate in areas of high bone activity, such as inflammation, infection, or tumors.
