| ［摘要］ 目的 分析超声弹性成像对校正乳腺超声影像报告数据系统（Breast Imaging and Reporting System Ultrasound，BI-RADS-US）3类及4类乳腺肿块的诊断价值。方法 对常规BI-RADS-US分类法诊断为3类及4类的乳腺肿块用超声弹性成像进行校正，以病理结果为金标准，对比分析校正前后的BI-RADS-US分类法对乳腺肿块良恶性的鉴别诊断效能。结果 常规BI-RADS-US分类法诊断乳腺良恶性肿块的灵敏度、特异度、准确度分别为75.6%、88.1%、83.8%，受试者工作特征（ROC）曲线下面积为0.836。经超声弹性成像校正后BI-RADS-US分类法的诊断灵敏度、特异度、准确度分别为82.9%、93.1%、90.8%，ROC曲线下面积为0.918。校正前后ROC曲线下面积比较差异有统计学意义(P<0.05)。结论 弹性成像有助于提高超声对BI-RADS-US 3类及4类乳腺肿块良恶性的鉴别诊断效能。 |

| Abstract: |
| ［Abstract］ Objective To analyze the value of Breast Imaging and Reporting System Ultrasound(BI-RADS-US) rectified by ultrasound elastography in diagnosis of type 3 and type 4 breast lumps. Methods Breast lumps of type 3 and type 4 diagnosed by conventional BI-RADS-US classification were diagnosed by ultrasound elastography as rectification. With the pathological results as the gold standard, the efficacies of BI-RADS-US classification were compared and analyzed in differential diagnosis of benign and malignant breast tumors before and after rectification. Results The sensitivity, specificity and accuracy of the conventional BI-RADS-US classification were 75.6%, 88.1% and 83.8% respectively in diagnosis of benign and malignant breast tumors, and the area under the receiver operating characteristic(ROC) curve was 0.836. The sensitivity，specificity and accuracy of the BI-RADS-US classification with ultrasound elastography rectification were 82.9%, 93.1% and 90.8% respectively, and the area under ROC curve was 0.918. There were significant differences in the areas under ROC curve before and after rectification(P<0.05). Conclusion Elastography is conducive to improving the diagnostic efficacies of ultrasound in the differential diagnosis of benign and malignant breast tumors of BI-RADS-US type 3 and type 4. |
