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.
作者采用一种将超声速度与体内人体桡骨光子吸收测定法相结合的方法，测量了骨中的声速（U）和骨矿物质含量（BMC）。然后，根据这些测量结果和一个“简单”的骨模型，他们计算出了骨矿物质密度、密质骨密度和弹性模量。对这些参数以及骨模型的准确性进行了评估，并给出了每个参数的正常值，并与已发表的值进行了比较。作者认为，与单独使用任一参数相比，U和BMC相结合能更好地区分骨质疏松症或代谢性骨病患者的正常与异常情况。
