摘要

目的：

探讨超声乳腺影像报告和数据系统（breast imaging reporting and data system，BI-RADS）分类结合剪切波弹性成像（shear wave elastography，SWE）诊断乳腺4类肿块的准确性。

方法：

对100例BI-RADS 4类乳腺肿块患者（共118个乳腺肿块）手术前行SWE检查，测量其最大弹性模量值（maximum elastic modulus，Emax）及与周边正常组织弹性比值（Ratio）2个参数。以病理学检查结果为金标准，进行受试者工作特征（receiver oper-ating characteristic，ROC）曲线分析，评价二者单独和联合应用的诊断效能。

结果：

弹性参数Emax和Ratio诊断BI-RADS 4类乳腺肿块的曲线下面积（area under curve，AUC）分别为0.880、0.902，准确率分别为79.7%、85.6%。二者联合应用时，诊断BI-RADS 4类乳腺肿块的准确率提高至92.4%。

结论：

SWE弹性参数Emax、Ratio在BI-RADS 4类乳腺肿块的良恶性鉴别诊断中有较高的诊断价值，超声BI-RADS分类与2个参数结合更能提高诊断准确率。

Abstract

Objective:

To investigate the accuracy of ultrasound breast imaging reporting and data system (BI-RADS) classification combined with shear wave elastography (SWE） in the diagnosis of 4 types of breast masses.

Methods:

SWE tests were performed on 100 patients with BI-RADS type 4 breast lesions (118 breast masses in total ) before surgery. The maximum elastic modulus (Emax) and the elastic ratio to surroun

ding normal tissues (Ratio) were measured. Receiver operating characteristic (ROC) analysis was carried out with pathological results as the gold standard to evaluate the diagnostic efficiency of the two alone and in combination.

Results:

The area under curve (AUC) of elastic parameter Emax and Ratio values in the diagnosis of BI-RADS type 4 breast masses were 0.880 and 0.902 respectively

and the accuracy were 79.7 % and 85.6 % respectively. When the two methods were used together

the accuracy of diagnosing BI-RADS type 4 breast masses was increased to 92.4 %.

Conclusion:

SWE elastic parameters Emax and Ratio have high diagnostic value in the differential diagnosis of benign and malignant BI-RADS type 4 breast masses. The combination of ultrasonic BI-RADS classification and the two parameters can improve the diagnostic accuracy.
