Bone density scan

    A bone density scan (DEXA) is used to check for osteoporosis, a condition in which the bones become weaker and more prone to fractures. Osteoporosis often develops slowly over time and may not cause noticeable symptoms until a bone breaks, which is why early detection through diagnostic imaging is so important. A private DEXA scan can help identify bone loss before fractures occur, allowing preventative steps or treatment to begin sooner.

    During the scan, X-rays measure the amount of calcium and other minerals contained within a specific area of bone. And while X-rays are part of the process, you are exposed to very low levels of radiation. 

    • A bone density test mainly determines the presence of osteoporosis. The most common bones tested are in the hip, spine and forearm.

      An osteoporosis diagnostic test can be helpful to:

      • Identify decreases in bone density
      • Determine a person's risk of fractures
      • Confirm osteoporosis is present
      • Determine the effectiveness of an osteoporosis treatment

      Bone density scans do not show the presence of arthritis.

    • In most cases, little to no preparation is required for a bone density scan. You may be advised to avoid calcium supplements for 24 hours before the test and to wear loose, comfortable clothing without metal fastenings.

      You should tell your doctor beforehand if you've recently had a barium exam or had contrast material injected for a CT scan or nuclear medicine test as contrast materials might interfere with your bone density test.

    • When you arrive for your appointment, a radiographer will explain the process and ensure you are comfortable before the scan begins. You will usually be asked to lie flat on a padded examination table, while a scanning arm passes slowly over the part of your body being examined.

      A small, portable machine can measure bone density in the bones at the far ends of your skeleton, such as those in your finger, wrist or heel.

    • Mayo Clinic Healthcare uses dual energy X-ray absorptiometry (DEXA) to measure bone density. Normally, the test shouldn’t last more than 30 minutes.

      Depending on your needs, specialists may scan bones that have signs of weakness or are most likely to break due to osteoporosis, such as:

      • Bones in your lower spine
      • Femur, where it meets your hip
      • Forearm bones

      Once the scan is complete, you can return to your normal daily activities immediately, with no recovery time required.

    • Older women are more likely to develop osteoporosis. However, men also are susceptible. Regardless of your sex or age, your doctor may recommend a private DEXA scan if you've:

      • Lost height
      • Fractured a bone
      • Take certain drugs, such as long-term use of steroid medications
      • Had a drop in hormone levels

      Mayo Clinic Healthcare will work with you to determine if a bone density scan is appropriate to your needs. If testing reveals low bone density, your private consultant will work with you to develop a treatment plan tailored to your specific condition.

    • After your scan, the results will be reviewed by a specialist and explained clearly, ensuring you understand what they mean for your bone health and next steps.
