目的

探讨超声造影(CEUS)与实时组织弹性成像(UE)联合评分对乳腺超声影像报告和数据系统(BI-RADS)诊断为4类的乳腺病灶的良恶性鉴别诊断价值。

方法

选取2012年4月至2016年2月在浙江大学医学院附属第二医院常规超声检查且诊断为BI-RADS 4类的158例患者共172个乳腺病灶行CEUS及UE检查,分别对每个病灶进行赋值评分,以穿刺或手术病理为金标准,构建ROC曲线,分析CEUS和UE联合评分法对BI-RADS 4类病灶的良恶性鉴别诊断价值。

结果

172个病灶中,病理学诊断良性80个,恶性92个,单独应用CEUS评分法分析乳腺BI-RADS 4类病灶的ROC曲线下面积(AUC)、敏感度、特异度、准确性分别为0.894、84.78%、85.00%、84.88%;单独应用UE评分法分析乳腺BI-RADS 4类病灶的ROC曲线下面积(AUC)、敏感度、特异度、准确性分别为0.844、82.61%、82.50%、82.56%。把造影和弹性评分法联合,以7分为诊断界点(AUC为0.951),其敏感度、特异度、准确性为94.57%、93.75%、94.19%,均高于单独评分法(P<0.05)。

结论

应用超声造影及弹性成像联合评分法能够明显提高乳腺BI-RADS 4类病灶的诊断准确率,可作为BI-RADS分类的补充,减少不必要的术前活检,值得临床推广应用。

Objective

To assess the value of scoring by contrast-enhanced ultrasound (CEUS) combined with ultrasonic elastography (UE) in the differential diagnosis of Breast Imaging Reporting and Date System for Ultrasound (BI-RADS-US) 4 lesions.

Methods

From April 2012 to February 2016, a total of 172 BI-RADS 4 lesions in 158 patients who underwent CEUS and UE at the Second Affiliated Hospital of Medical College of Zhejiang University were included. The scores of each lesion were evaluated. The diagnostic results were compared with biopsy or operative pathology. ROC curve was used to analyze the value of scoring by CEUS combined with UE in the differential diagnosis of BI-RADS 4 lesions.

Results

Among the 172 lesions, pathological diagnosis showed benign lesions in 80 cases, and malignant lesions in 92. The area under the ROC curve (AUC) of CEUS scoring alone was 0.894, and the sensitivity, specificity, and accuracy were 84.78%, 85.00%, and 84.88%, respectively. The area under the ROC curve (AUC) of UE scoring alone was 0.844, and the sensitivity, specificity, and accuracy were 82.61%, 82.50%, and 82.56%, respectively. When the cut-off value of the score of CEUS combined with UE was set at 7, the AUC was 0.951, and the sensitivity, specificity, and accuracy were 94.57%, 93.75%, and 94.19%, respectively, which were all higher than those of the two modalities alone (P<0.05).

Conclusion

Scoring by CEUS combined with UE can significantly improve the accuracy in the diagnosis of BI-RADS 4 lesions, and it can be used as a supplement to the BI-RADS classification to reduce unnecessary preoperative biopsy.
