摘要
目的:探讨侧位腰椎测量法(LS)和侧位脊柱测量法(LVA)所得到的腰椎骨密度值是否一致。方法:应用GE Lunar Prod igy双能X线骨密度仪(DXA)采取两种不同的测量方法,即LS和LVA,共测量54个椎体,对骨密度值的分布情况进行探索性研究,结果用箱线图表示,比较两者的测量结果,对配对样本比较采用W ilcoxon符号秩和检验,并进行Pearson相关分析。结果:两种方法测量得到的骨密度值分布基本一致,经W ilcoxon符号秩和检验,两组结果无显著性统计学意义(P>0.05),两者有极显著相关关系(P=0.000)。结论:用GE Lunar Prod igy DXA采取两种方法测量的侧位腰椎骨密度结果是一致的。
Objective : To investigate the consistency of two methods in the measurement of bone mineral density in the lateral lumbar vertebra. Methods:The bone mineral densities of the 2nd, 3rd and 4th lumbar vertebras in 18 female patients, at a preset side lying position, were measured respectively by two methods (lateral spine analysis, LS and lateral vertebral analysis, LVA) provided by the dual-energy X-ray absorptiometry (GE Lunar, Prodigy). The results were recorded and analyzed by SPSS (Version 10.0). The values of bone mineral density were displayed by boxplot, paired and analyzed by Wilcoxon's signed rank test and Pearson's correlation analysis. Statistical significance was considered when P 〈 0.05. Results :The data distributions measured by the two different methods were accordant. The data form the two groups were not statistically different under Wilcoxon's signed rank test (P 〉 0.05 ) , and were clearly correlated ( P 〈 0. 001 ) under Pearson's correlation analysis. Conclusion : The results of the two methods for the measurement of bone mineral density in the lateral lumbar vertebras were coherent.
