目的：探讨数字化X线局部加压放大摄影在诊断乳腺疾病方面的价值。方法常规摄影及联合局部加压摄影检查并手术病检100例，所有患者采用常规体位摄影检查，对常规摄影不能明确诊断的病灶进一步采取局部加压放大摄影，使用美国放射学会推荐的乳腺影像报告和数据系统（ BI-RADS）对病变诊断评价分类，统计分析方法采用χ2检验，比较局部加压前后两组诊断结果与病理结果符合率。结果100例乳腺占位性病变，病理诊断71例良性及29例恶性。常规体位明确诊断43例，诊断良性病变31例及恶性病变12例，需要活检43例，14例需结合其他影像学检查进一步评价，诊断恶性病变病理符合率41．3％，诊断良性病变病理符合率43．6％；经局部加压放大摄影后明确诊断81例，诊断良性病变57例及恶性病变24例，需要活检16例，需结合其他影像学检查进一步评价3例，诊断恶性病变病理符合率82．7％，较常规摄影提高41．4％，诊断良性病变病理符合率80．2％，较常规摄影提高36．6％。两组评价结果差异有统计学意义（ P＜0．05）。结论数字化X线局部加压放大摄影较常规体位摄影可提高良恶性病变诊断与病理结果符合率，为常规体位摄影提供有效补充。%Objective To study the value of digital X-ray mammography with partial compression in di-agnose ofbreast disease .Methods 100 cases of patients with breast mass received examination with routine posi-tion photography and partial compression photography .Breast Imaging Reporting And Data System ( BI-RADS ) was adopted to classifythe lesions , and the diagnostic results before and after partial compression photography was compared with pathological results .Results 43 cases of breast mass was clearly diagnosed by routine posi-tion photography in 100cases of patients , including 31 cases of benign lesions and 12 cases of malignant le-sions .The accurate rate of malignant evaluation results was 41 .3%,and the accurate rate of benign evaluation results was43 .6%.81 cases were clearly diagnosed by partial compression photography ,including5,7 cases of benign lesions and 24 cases of malignant lesions .The accurate rate of malignant or benign evaluation results was 82 .7 %,and 80 .3%,respectively ,which was much higher than those of routine position photography group ( P<0 .01 ) .Conclusion The digital X-ray mammography with partial compression photography can improve diag-nose accurate rate of breast mass and provide an effective supplement for routine position photography .
