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.A DXA scanner is a machine that produces two X-ray beams, each with different energy levels. One beam is high energy while the other is low energy.ased on the difference between the two beams, the bone density can be measured. At present, DXA scanning focuses on two main areas -- the hip and spine. In certain situations -- if the hip or spine can't be measured, for instance -- it is measured in the forearm.
