The Brain and Spine Institute is made up of experts in the field of neuroscience in order to bring patients the best healthcare in East Tennessee for a full range of neurological diseases and disorders.
A three-phase bone scan is a medical test that is performed when osteomyelitis is suspected. Osteomyelitis is an inflammation of bone, especially bone marrow, that is caused by a pathogenic organism. Example bone scan images are made immediately, five hours, and 25 hours after tracer injection.
The patient will receive an injection of 99m-Technetium-MDP in a vein in the arm. Images are obtained in three phases: immediately after the injection; four hours after the injection; and 24 hours after the injection. Each scan requires about 20 minutes in order to obtain satisfactory images. For each scan, the patient will lie motionless on a bed while the scanner images the bone.
Technetium-99 is a widely-used isotope in Nuclear Medicine. It has a short half-life (6 hours) so that the material soon leaves body tissues. It emits gamma radiation (high energy photons) of appropriate energy for detection by gamma cameras. The technetium is attached to a pharmaceutical agent (MDP) that localizes in bone that is active or inflamed. No allergic reactions are experienced with this test.
