摘要
本文讨论了描述骨质 疏松的数学方法,分析了双能X光骨密度仪测量的骨密度参数的物理意义,找出了以骨密度为指标的骨质疏松诊断标准造成误诊与漏诊的原因,介绍了骨强度指标-抗骨折能力的概念及其在临床上的应用。最后简单介绍了目前临床上诊断骨质疏松的设备。
This article discu-sses the mathem-
atical modeling method for describing bone loss or osteoporosis, analyzes the physical meaning of bone mineral density (BMD), and demonstrates the causes of misdiagnosis that frequently happens with the (BMD) standard. This article introduces the method of the bone strength analysis and the principle to overcome the misdiagnoses related with the BMD standard, and finally introduces the functions of clinically applied bone density and strength instrumentation systems.
