Bone Scan

A bone scan is a nuclear imaging test used to do the following:

  • Diagnose bone conditions — most often, cancerous bone tumors and cancer that has spread to the bone (metastasized) from other parts of the body
  • Determine how much cancer is in the bones before and after treatment (known as “staging”) to see whether the treatment is working

For the test, a very small amount of a radioactive material (radionuclide) is injected into the patient’s bloodstream. This material gradually wears off but leaves behind small amounts of radiation that can be seen using a special scanner. Any area where the radionuclide remains, called a “hot spot,” may indicate a problem with the bone.

The scan is painless, and there are no side effects from the injection or the radionuclide.

Do I need a bone scan?

A doctor at Rush may recommend a bone scan for the following reasons:

  • To diagnose a cancerous or noncancerous bone tumor
  • To see if cancer has spread (metastasized) to the bones from another part of the body
  • To diagnose fractures that don’t show up on an X-ray
  • To see whether a bone is infected (osteomyelitis)
  • To figure out what is causing bone pain if other tests can’t pinpoint the cause
  • To detect other conditions, such as the following:
  • To follow the progress of treatment to see whether the treatment is working
