What is a DEXA scan for the bones?
Dual X-ray absorptiometry (DXA) is the preferred technique for measuring bone mineral density (BMD). DXA has also been called dual energy X-ray absorptiometry, or DEXA. DXA is relatively easy to perform and the amount of radiation exposure is low.
What is a DEXA scan used for?
Bone density scanning, also called dual-energy x-ray absorptiometry (DXA) or bone densitometry, is an enhanced form of x-ray technology that is used to measure bone loss. DXA is today’s established standard for measuring bone mineral density (BMD).
What is a bone density scan?
Bone densitometry is a test like an X-ray that quickly and accurately measures the density of bone. It is used primarily to detect osteopenia or osteoporosis, diseases in which the bone’s mineral and density are low and the risk of fractures is increased.
