Bone Densitometry (DEXA)
Also known as Dual-energy X-ray Absorptiometry (DEXA), bone densitometry scan uses very low radiation x-ray beams to measure the density of mineral in bone and to evaluate bone density loss. The test is used to diagnose osteoporosis, a bone condition that develops as a result of calcium loss in bones, causing bones to become thinner and more prone to break. A DEXA scan can also be used to assess an individual risk for incurring fractures.
