A bone scan's sensitivity to variation in bone metabolism and its ability to scan the entire skeleton make it very helpful in diagnosing a wide range of bone disorders. The test poses no greater risk than do conventional X-ray procedures. The tracers used in a bone scan produce very little radiation exposure.

You might find the injection and the need to lie still during the scanning procedure mildly uncomfortable. The risk of an allergic reaction to the tracers is low.
