Ultrasound elastography (UE) is a novel imaging method. The purpose of this study was to determine the utility of Virtual Touch tissue imaging in the evaluation of solid breast lesions.
209 breast solid lesions in 192 patients that had been evaluated using ultrasound (US) and UE were reviewed and analyzed.
The sensitivity, specificity, accuracy, positive predictive value, and negative predictive value for UE, US, and US plus UE in the differentiation of malignant from benign breast lesions were 80.8, 75.6, 77.9, 73.1, and 82.8% for UE, 87.2, 86.1, 86.6, 83.7, and 89.2% for US, and 92.5, 86.9, 89.5, 85.3, and 93.4% for US plus UE. There were significant differences between UE and US plus UE (all p < 0.05). Except for accuracy, there were no significant differences between UE and US or US and US plus UE (all p > 0.05). The area under the curve obtained from the ROC curve for UE, US, and US plus UE in differentiating malignant from benign lesions was 0.845, 0.884, and 0.922, respectively.
The UE scoring system is not superior to BI-RADS in the sonographic evaluation of solid breast lesions. Combined use may improve the performance.
超声弹性成像（UE）是一种新型成像方法。本研究的目的是确定虚拟触诊组织成像在评估乳腺实性病变中的效用。
回顾并分析了192例患者的209个经超声（US）和UE评估的乳腺实性病变。
UE、US以及US联合UE鉴别乳腺良恶性病变的敏感度、特异度、准确度、阳性预测值和阴性预测值分别为：UE为80.8%、75.6%、77.9%、73.1%和82.8%；US为87.2%、86.1%、86.6%、83.7%和89.2%；US联合UE为92.5%、86.9%、89.5%、85.3%和93.4%。UE与US联合UE之间存在显著差异（所有p<0.05）。除准确度外，UE与US之间或US与US联合UE之间无显著差异（所有p>0.05）。UE、US以及US联合UE鉴别良恶性病变的ROC曲线下面积分别为0.845、0.884和0.922。
在乳腺实性病变的超声评估中，UE评分系统并不优于乳腺影像报告和数据系统（BI-RADS）。联合使用可能会提高性能。
