The NOF says a test called Dual-energy X-ray absorptiometry, or DXA, is the best test for osteoporosis. DXA uses radiation from x-rays.

国家骨质疏松基金会说，一种叫作双重能量X 射线吸光测定法，或是DXA是用来诊断骨质疏松症的最佳途径。

Objective To evaluate consistency of bone mineral density(BMD) measurement and osteoporosis(OP) diagnosis between tibial quantitative ultrasonometry(QUS) and dual energy X-ray absorptiometry(DXA).

目的评价胫骨定量超声（QUS）和双能X线吸收法（DXA）在骨密度（BMD）测量和骨质疏松（OP）诊断中的一致性。
