What Is a Total Body Nuclear Bone Scan?

A nuclear bone scan will detect if your bones have a lower or an increased level of bone metabolism than is considered normal. It identifies tumors, fractures, infections and other abnormalities using a radiotracer that is injected into the bloodstream.

Why These Scans Are Used

• If you have battled certain cancers like breast, kidney, thyroid or prostate, your doctor may order a nuclear bone scan. These types of cancers can spread to the bones and metastasize. Arthritis, joint infections or even replacements or unexplained bone pain are also reasons your doctor may write an order for a bone scan.

The Injection

• The test is performed by injecting radionuclide through a vein in your arm. This substance is chosen because its properties collect in the bones.

After the Injection

• You will be free to walk or sit over the next three or hour hours. You will be asked to consume large amounts of water and to urinate frequently so the radioactive material doesn't accumulate in your bladder, obstructing the doctor's view of your pelvis.

During the Scan

• During the scan, you will be asked to lie on your back and remain very still. The gamma camera will be placed on the body part that is being examined. The table may change position during the scan as you are studied from head to toe. This process takes about an hour.

After the Scan

• You will be asked to drink plenty of fluids after the scan. This will aid in eliminating the radiosotope. It will be almost totally eradicated within 24 hours.
