Dual Energy X-ray Absorptiometry

Dual energy X-ray absorptiometry (DEXA) is a test that measures the density of your bones. The DEXA scan is an x-ray scan that uses a small amount of radiation to take pictures of different bones. These pictures are used to measure the density of the bones at the spine, hip, and forearm. It can also take pictures of other bones such as a finger or the heel bone. Measurements of the spine and hip are called central DXA. Those done on the arms or legs are called peripheral DXA. In some cases, your doctor may order a whole body scan.

  • Call Your Doctor

    Call your doctor if you have any questions about your condition, the test, or your test results.

  • What to Expect

  • Reasons for Test


    This test will help your doctor assess the density of your bones. It will help determine if you have
    osteoporosis, a bone-thinning disease. This information may be used to predict your risk of bone fractures.

  • Possible Complications

    An x-ray uses radiation to make images. The low levels of radiation from a single x-ray will not affect most people. If you are pregnant or think you may be pregnant, talk to your doctor before getting an x-ray. Radiation may be harmful to developing babies.
