采用超声声速法和光子吸收法在人体半径内测量声速(U)和骨矿物质含量（BMC）。根据这些测量结果和一个“简单”的骨骼模型，他们计算出骨矿物质密度、致密骨密度和弹性模量。评估这些参数和骨模型的准确性，并给出每个参数的正常值，并与已公布的值进行比较。作者认为，在骨质疏松症或代谢性骨病患者中，U和BMC的结合比单独使用任何一个参数都能更好地区分正常和异常。
Using a method combining the velocity of ultrasound and photon absorptiometry in the human radius in vivo, the authors measured the speed of sound in bone (U) and bone mineral content (BMC). From these measurements and a "simple" bone model, they then computed the bone mineral density, compact bone density, and modulus of elasticity. The accuracy of these parameters and of the bone model is assessed, and normal values for each parameter are given and compared with published values. The authors feel that a combination of U and BMC permits better discrimination between normal and abnormal in patients with osteoporosis or metabolic bone disease than either parameter alone.
