彩色多普勒血流显像与超声弹性成像联合诊断BI-RADS4类乳腺病变

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BIRADS4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-RADS 4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 132patients with BI-RADS 4 breast lesions.Results There were 75 benign lesions and 57malignant 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 BIRADS 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＜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.
