摘　　要：目的探讨超声的美国放射学院乳腺影像报告和数据系统(breast imaging reporting and data systern,BI-RADS)分类对微小乳腺癌的诊断价值。方法回顾性分析超声的BI-RADS分类的98例微小乳腺病灶的病理结果、分级结果与超声征象。结果超声的BI-RADS分类对微小乳腺癌的阳性预测值、阴性预测值、敏感度、特异度以及准确度分别为88.46%、83.33%、65.71%、95.23%和84.69%。恶性病灶组边缘不光整、形态不规则、内部有微钙化、后方回声衰减、周围组织改变、纵横比≥1以及内部血流RI≥0.7的占比显著高于良性病灶组,差异具有统计学意义(P<0.05)。结论超声的BI-RADS分类可客观地评价微小乳腺病灶的良恶性。Objective To discuss the ultrasound breast imaging reporting and data systern(BI-RADS)in the diagnosis of breast tiny carcinoma.Methods Retrospectively analyzed ultrasound features,BI-RADS classification and pathological results of 98 small breast lesions diagnosed to be ultrasound BI-RADS.Results The positive predictive value,negative predictive value,sitivity,specificity and accuracy of ultrasound BI-RADS classi-fication were 88.46%,83.33%,65.71%,95.23%and 84.69%,respectively.The differences in non-circumscribed margin,irregular shape,microcalcification in mass,shadowing,the changes of surrounding tissue,aspect ratio>1 and lesions internal resistance index(RI)≥0.7 between Benign lesions group and Malignant lesions group were statistically significant different(P<0.05).Conclusion BI-RADS classification of ultrasound can objectively evaluate benign and malignant breast lesions.
