A DEXA scan is a special type of??X-ray??that measures bone mineral density (BMD).
DEXA stands for “dual energy X-ray absorptiometry”.??This type of scan may also be called:
- a DXA scan
- a bone density scan
- a bone densitometry scan
DEXA scans are often used??to diagnose or assess someone’s risk of??osteoporosis, a condition??that weakens bones and makes them more likely to break.
As well as being quick and painless, a DEXA scan is more effective than normal X-rays in identifying low bone mineral density.
