Bone function: Bone scan involves intravenous injection of radio tracer usually technetium 99m mdp which accumulates in skeleton.Scan with camera: early phase(5-10 min) and late phase(2-3 hr) imaging. Increased uptake is seen in fractures, tumors, infection, etc. Decreased activity is seen in metal artifacts, aggressive tumor/infection, ; loss of blood supply to bones. Bone scan very sensitive but not specific.
