【摘要】目的:探讨多层螺旋CT(MSCT)评判腰椎形态和骨组织细微结构改变、测量腰椎指数及松质骨CT值这3种方法在老年性骨质疏松症中的诊断价值.方法:对100例经双能X线骨密度仪检测诊断为老年性骨质疏松症病例行腰椎MSCT扫描,分别行形态和骨组织细微结构改变评判、腰椎指数测量、松质骨CT值测量等方法评判,将评判和测量结果采用x2检验.结果:100例病例中,骨密度T值从-5.1~-2.5,平均-3.5±0.8;腰椎形态和骨组织细微结构改变评判:19例正常,轻度骨质疏松28例,中度4例,量度49例;腰椎指数评判:88例正常,轻度骨质疏松7例,中度5例,无重度骨质疏松患者;CT值测量评判:8例正常,轻度骨质疏松6例,中度9例,重度77例.结论:3种评判方法各有优劣,以CT值测量法骨质疏松症检出率最高.三者结合能提高骨质疏松症诊断准确性,为全面评价骨质疏松症,评估骨质疏松性骨折提供有力的客观依据.%Objective:To investigate the diagnostic value of multi-slice spiral CT (MSCT) with three methods in evaluating shape and bone fine structure changes of lumbar vertebrae,lumbar index and CT value in cancellous bone of elderly population with osteoporosis. Methods: 100 cases of elderly population with osteoporosis diagnosed by dual energy X-ray ab-sorptiometry (DEXA) underwent lumbar vertebrae MSCT examination. The shape and fine structure changes of lumbar vertebrae,lumbar index
