摘　　要：目的通过对双能X线骨密度测量仪(dual X-ray absorptiometry,DXA)骨密度报告的影像分析,评估操作者的骨密度测量质量。方法收集18所参加多中心药物试验医院DXA的腰椎和股骨近端测量报告共2 160例次。分别依据DXA测量报告所示信息及其影像所见,分析平均不合格率与操作者的职称类别、所在科室类别、DXA机型种类、是否接受过骨密度测量授课培训等因素之间的差异及与DXA操作者工作年限等因素之间的关系。结果 DXA操作者职称类别的技师和护士之间的平均不合格率比较,差异有统计学意义(P=0.000);平均不合格率与DXA所在科室类别除放射科与核医学科间差异有统计学意义(P=0.023),其余科室间比较,差异无统计学意义(P>0.05);操作者是否接受过骨矿含量测量授课培训与其相应的平均不合格率比较,差异均有统计学意义(P=0.000);DXA机型类别比较,差异无统计学意义(P=0.859);DXA操作者工作年限与其不合格率无显著相关性(r=0.293,P=0.237)。结论操作者的操作对DXA测量质量至关重要,在临床应用DXA测量前,建议现场培训有关操作人员。Objective To evaluate the quality of dual X-ray absorptiometry（ DXA） measurements by operators,which was based on image analysis from DXA reports. Methods Totally 2 160 of spine and femur DXA reports from 18 hospitals in multi-center trials were reviewed in the study. Factors such as operator＇s years of experience,position,employed departments,training history,as well as device system for DXA measurements were analyzed in comparison with the overall failing rate,respectively. Spearman rank correlation and Chi-Square were used for statistical analysis.Results Failing rates show significant（ P = 0. 000） difference between operator＇s positions（ technician and nurse）,employed departments（ radiology and nuclear medicine）,as well as training history. In addition,no significant（ P〉0. 05） result was presented between failing rate with the rest employed departments and with device system for DXA measurement,respectively. Also,there was no significant correlation between operator＇s years of experience with the failing rate（ r = 0. 293,P = 0. 237）. Conclusion Operator＇s performance may play an important role in implementing the quality of DXA measurement. Hands-on training for operator should be suggested before clinical application of bone mineral density measurement with DXA.
