Tests and diagnosis

By Mayo Clinic Staff

If you have a mild form of fibrous dysplasia, you may not know it until it's discovered incidentally on an X-ray for another condition. If you have signs and symptoms, your doctor will perform a physical examination and order X-rays of the affected bones.

In some cases, your doctor may order more tests to confirm the diagnosis or to determine the extent of the disorder. They include:

  • Imaging tests. Computerized tomography or magnetic resonance imaging scans may be used to determine how extensively your bones are affected.
  • Bone scan. This test uses radioactive tracers, which are injected into your bloodstream. The damaged parts of your bones take up more of the tracers, which show up more brightly on the scan.
  • Biopsy. This test uses a hollow needle to remove a small piece of the affected bone for laboratory analysis.
