Bone / Skeletal Scan

What is a nuclear bone scan?

A nuclear bone scan is performed by injecting a small amount of radioactive tracer (Tc-99m and a phosphate) into the body.

Why is it performed?

There are a number of reasons your doctor may choose to perform a nuclear bone scan. These include:

  • To assess the source of pain in the bones (eg. back, joint, rib pain etc.)
  • To supplement or confirm findings from other scans and test results, such as x-rays, computed tomography (CT) scans and magnetic resonance imaging (MRI).
  • To assess and diagnose certain fractures
  • To diagnose infections of the bone and skin
  • To check what kind of response you are having to certain medications or treatments (eg. after chemotherapy)
  • To diagnose or evaluate cancer in the bones
  • To evaluate an abnormal gait in children or toddlers

How does it work?

First, you will be injected with a small amount of radioactive tracer, and images will be taken of the area of your body that is being scanned. This part of the process is referred to as early imaging, and may not be necessary, depending on your doctor's recommendation.

The second part of the process occurs after two to four hours. This part of the scanning process is known as delayed imaging, as the radioactive material has been absorbed into the bones by this stage.

After the scan, the radioactive tracer will be eliminated from your body through urination and decay.It is important to drink enough fluids after your scan and to void as often as you can.
