目的：探讨乳腺钼靶摄影质量控制在乳腺疾病诊断中的价值。方法：将2069例行乳腺钼靶X线检查并经手术或穿刺活检证实的患者纳入本研究中，其中质量控制组1210例共1338个病灶，未行质量控制组（对照组）859例共942个病灶。将钼靶检查结果与病理结果进行对照分析，比较两组中乳腺钼靶检查的诊断敏感度、特异度及诊断符合率。结果：质量控制组中乳腺钼靶检查的诊断敏感度、特异度和诊断符合率分别为91．89％、88．99％和90．06％，对照组中分别为85．09％、86．17％和85．77％，两组中诊断敏感度和符合率的差异有统计学意义（P＝0．002、0．002），特异度的差异无统计学意义（P＝0．105）。结论：实行在乳腺钼靶摄影中实施质量控制后，对乳腺疾病的诊断敏感性和准确性均有提高。%Objective:To evaluate the effect of quality control for mammography in the diagnosis of breast disease. Methods:2069 cases with breast lesions who underwent mammography and the results confirmed by operation or puncture biopsy were recruited in this study.In 1210 cases (1328 lesions)qualilty control of mammography was carried out (grouop A,as study group);in other 859 cases (942 lesions)no quality control was carried out (group B,as control group).The mammographic diagnosis of both groups was compared with the pathologic results,and the sensitivity,specificity and accu-racy of mammographic diagnosis in both groups were compared.Results:comparing the result of mammography with the re-sults of operation/pathology,the sensitivity,accuracy and specificity of the study group were 91.89%,88.99%and 90.06%respectively,while for the control group they were 85.09%,86.17% and 85.77%.The sensitivity and accuracy difference of the two group were statistically significant (P= 0.002.P= 0.002,but the specificity difference was statistically insignifi-cant (P= 0.105).Conclusion:According to the results of this study,the sensitivity and accuracy of diagnosing mammary dis-ease is improved significantly when a set of quality control for mammography is set up.
