DEXA, also known as bone densitometry, is a quick and painless X-ray that measures bone density. It is most often used to detect osteoporosis, but it can also assess your risk for developing fractures. If you are already being treated for bone loss, a follow-up DEXA can show if the therapy is effective.
What to Expect
Before the exam, we'll ask you to change into a gown and answer any questions you may have. During the exam, an X-ray technologist will position you on a padded table and ask you to remain very still. The DEXA equipment will scan one or more areas of bone, usually the hip and spine, where most osteoporosis-related fractures occur. DEXA will compute a numerical reading of bone strength, called a T-score. A radiologist will interpret the results and a report will be sent to your physician, who will discuss the findings with you.
Preparing for Your Bone Densitometry
You may eat and drink normally on the day of your exam.
Inform your physician or X-ray technologist if you are or may be pregnant.
The procedure takes approximately 10-20 minutes.
