摘要
采用ＱＤＲ４５００Ａ型双能Ｘ线骨密度仪，以探讨绝经后骨质疏松症骨密度的最佳测量部位及指标。结果表明：骨密度比骨矿含量及骨表面积更能反映绝经后骨量减少的情况；腰椎骨密度比前臂骨密度，全身脊椎骨密度及股骨上段骨密度更能反映绝经后骨量减少的情况；腰３，４侧位中点（感兴趣区）骨密度受绝经年限影响最大。
As the function of most bone mineral measuring machine is limited, either by single photon absorptiometry(SPA), dual photon absorptiometry(DPA), speed of sound(SOS), or dual energy x ray absorptiometry(DEXA), it is hard to evaluate the best place and index of postmenopausal bone loss at many positions by one machine at the same time. So we used QDR4500A, one of the best advanced DEXA which has a good repeatability, to search the best place and index for postmenopausal bone loss. The results showed that (1) bone mineral density(BMD) was better than bone mineral content(BMC) and Area to reflect this kind of bone loss; (2) lumber BMD was a better place than the forearm BMD, total spine BMD and other places; and (3) midlateral L3,4 BMD was a best index for postmenopausal bone loss.
