Bone Scan - indications and procedure details

Skeletal scintigraphy (or bone scan), is a valuable nuclear medicine examination with a wide variety of indications. Most common include: osseous metastases detection, evaluating for the presence of osteomyelitis, assessing for prosthetic hardware infection or loosening. The procedure starts with the intravenous injection of a radiotracer Tc99m-MDP. It is than followed by imaging at multiple time points and phases. For children it is normal to have additional intense uptake in the physes of the long bones- growth centers. In a healthy adult symmetric uptake should be seen throughout all the osseous structures. Extraosseous activity is seen in the kidneys and bladder as those excrete T99m-MDP. Most common complications of this procedure are based on a proper injection failure. More by the link.
