Bone Scan
A bone scan detects areas of increased or decreased bone metabolism and is used to identify abnormal processes involving the bone such as tumor, infection or fracture.
A radiotracer (bone-seeking radionuclide) is injected into the bloodstream through a vein. As it decays, the radiotracer emits gamma radiation, which is detected by a camera that slowly scans your body and ultimately creates an image.
Preparation
There is no preparation for this test. There is a consent form for this procedure.
Procedure
Testing requires placement of an IV and that you lie still on a table during scanning. There is a 3-hour delay between the administration of the radiotracer and the actual scan, which gives the tracer time to collect in the bones. During this time, you are able to leave the hospital returning later for the actual scan.
The scanning portion of the test will last about an hour.
