A simple, quick and low-dose scan that measures bone strength, used to assess and monitor osteoporosis and fracture risk
A DEXA scan is a simple test that measures the density, or strength, of your bones. It is the standard way to assess for osteoporosis and to judge the risk of fracture. The scan is quick, painless and uses only a very low dose of radiation, much less than many ordinary X-rays.
Written for patients and reviewed by Dr Liubov Borukhson, Consultant Rheumatologist (GMC 7021928).
A DEXA scan helps to:
The scan is straightforward. You lie comfortably on a couch while a scanning arm passes over you, usually measuring the hip and spine. It takes only a short time, you remain fully clothed for most setups, and there is nothing to recover from afterwards. You can return to your normal activities straight away.
The result is given as a score that compares your bone density with an expected value. On its own, though, a number means little. What matters is how it is interpreted alongside your age, history and other risk factors to build a complete picture of your bone health and fracture risk.
Dr Borukhson arranges DEXA scanning where appropriate as part of a wider bone-health assessment, and explains what the results mean for you and what, if anything, should be done. You can read more on the osteoporosis page.
Your GP can also help arrange a DEXA scan. Seeing Dr Borukhson, however, often means the scan can be arranged more quickly, and that the result is reviewed by a rheumatology specialist and acted on without delay, all as part of a single, joined-up assessment of your bone health.
A DEXA scan, interpreted as part of a full assessment, can clarify your bone strength and fracture risk and guide the right plan
