摘　　要：目的:探讨分析基于放射吸收法(RA)与双能X射线吸收法(DEXA)骨密度测量的相关性。方法:选取30只手部标本分别应用自主研发基于RA骨密度测量软件与Hologic公司的QDR-2000骨密度分析软件进行测量分析和计算。结果:配对比较在F检验的整体结果有显著性的条件下进行,采用线性回归分析对关联进行评估,RA与DEXA之间具有显著相关性(r=0.7798,P<0.05),并呈中高度相关。结论:自主开发的骨密度测量软件性能稳定,价格低廉,具有广阔的应用前景。Objective： To investigate the correlation between BMD based on DR and DEXA. Methods： A total of 30 cadaver hand specimens were measured by bone mineral density measurement software based on RA developed by us and Hologic QDR-2000. Results： The overall results of F test were significant so that the data were analyzed by SPSS16 statistical software（r=0.7798, P＆lt;0.05）. It is moderately and highly correlated between RA and DEXA. Conclusion： Self-developed software has a bright future because it is accurate and cheaper compared to foreign software.
