摘　　要：目的探讨彩色多普勒血流显像(CDFI)与超声弹性成像(UE)联合诊断乳腺影像报告和数据系统(BI-RADS)4类乳腺病变的价值。资料与方法 132例BI-RADS4类乳腺病变,根据病变血流Adler半定量分级及弹性评分对BI-RADS分类进行调整,绘制ROC曲线,比较BI-RADS分类及校正BI-RADS分类。结果 132例病灶中,良性病灶75个,恶性病灶57个。CDFI诊断乳腺癌的敏感度为87.72%,特异度为48.00%,准确度为65.15%;UE诊断乳腺癌的敏感度为87.72%,特异度为61.33%,准确度为72.73%。校正BI-RADS分类诊断4类乳腺病变的ROC曲线下面积为0.845,明显高于BI-RADS分类的0.760(Z=2.963,P<0.01)。结论 CDFI联合UE可以明显提高对BI-RADS4类乳腺病变的诊断准确率,有效减少不必要的术前活检。Purpose To investigate the value of combined color Doppler flow imaging （CDFI） with ultrasound elastography （UE） in diagnosing BI-RADS 4 breast lesions. Materials and Methods The corrected classification based on the semi-quantitative grading and elasticity score of diseased blood flow Adler, ROC analysis, comparison of BI-RADS classification and corrected BI-RADS classification were applied in 132 patients with BI-RADS 4 breast lesions. Results There were 75 benign lesions and 57 malignant lesions. The sensitivity, specificity and the accuracy rate of CDFI were 87.72%, 48.00% and 65.15%, respectively; and which of UE were 87.72%, 61.33% and 72.73%, respectively in the diagnosis of breast cancer. The area under ROC curve of correction BI- RADS classification in the diagnosis of breast lesions was 0.845, and it was significantly higher than that of the BI-RADS classification （Z=2.963, P＆lt;0.01）. Conclusion Combined CDFI with UE can significantly improve the diagnostic accuracy of the BI-RADS 4 breast lesions, and effectively reduce unnecessary preoperative biopsy.
