Abstract

An average, variable precision error of up to 6% related to source age was observed for dual-photon absorptiometry of the spine in a longitudinal study of bone mineral content involving 393 women. Application of a software correction for source decay compensated for only a portion of this error. The authors conclude that measurement of bone-loss rates using serial dual-photon bone mineral measurements must be interpreted with caution.

摘要

在一项涉及393名女性的骨矿物质含量纵向研究中,对脊柱进行双能X线吸收法测量时,观察到与源年龄相关的平均可变精度误差高达6%。应用软件对源衰减进行校正仅能补偿部分误差。作者得出结论,使用连续双能X线骨矿物质测量来测定骨质流失率时必须谨慎解读。
