What is a dual energy X-ray absorptiometry (DXA or DEXA) scan?

ANSWER

DXA scanning is used to test bone density -- how strong your bones are. It focuses on two main areas -- your hip and your spine. These areas can give your doctor a good idea of whether you’re likely to get fractures in other bones in your body.
