What does a healthy bone scan look like?

normal uptake. Bone scan involves intravenous injection of radiotracer usually technetium 99m mdp which accumulates in skeleton. Scan may involve early phase(5-10 min) and late phase(2-3 hr) imaging. Increased uptake is seen in fractures, tumors, infection, etc. Decreased uptake is seen in metal artifacts, aggressive tumor/infection, & loss of blood supply to bones.No abnormal uptake in skeleton is normal.
