What happens during a DXA scan
Measuring bone density
Bone density is measured using a DXA (dual energy X-ray absorptiometry) scan.
You will be asked to lie on a bed and stay still while the scanner, a kind of X-ray machine, moves over the different parts of your body being scanned. The procedure is painless and will take approximately 15 minutes.
