A DEXA scan (dual-energy X-ray absorptiometry) is a quick, painless test that measures bone mineral density (BMD). It is the standard way to detect osteoporosis.
Who should consider a DEXA scan
- Women after menopause and men over 50, especially with risk factors.
- Anyone who has had a fracture from a minor injury.
- People on long-term steroids or with conditions affecting bone.
What to expect
You lie comfortably on a table while a scanner passes over your hip and spine. It takes only a few minutes, uses a very low dose of radiation, and needs no injections or preparation.
