- an imaging investigation of the musculoskeletal system using radioactive tracers. Technetium-99m phosphate is injected intravenously and absorbed into the hydroxyapatite crystals of bone. It concentrates in areas of increased blood flow and metabolism, such as areas of infection, trauma, and neoplasia, before giving off radiation that can be detected by a gamma camera, which produces a map or scan of activity in the target area. A bone scan is particularly useful in the diagnosis of subtle fractures (including stress fractures), avascular necrosis (see osteonecrosis), osteomyelitis, and loosening of orthopaedic implants.
