摘要目的：探讨声触诊组织成像（VTI）及声触诊组织成像量化（VTIQ）技术在乳腺实性小结节鉴别诊断中的应用价值。方法：收集我院甲乳外科住院治疗的52例患者共计60个乳腺实性小结节，先行常规超声检查，并对结节进行BI-RADS分类，后行VTI及VTIQ检查，通过VTI成像获得结节的硬度评分，通过VTIQ成像获得结节的剪切波速度值（SWV）。以病理诊断为金标准，绘制受试者工作特征曲线（ROC），获得VTIQ技术诊断乳腺实性小结节的截断值，并评价BI-RADS分类、VTI及VTIQ技术对乳腺实性小结节良恶性的诊断价值。结果：乳腺实性小结节恶性组VTI硬度评分４分及以上所占比例（16/18）显著高于良性组（11/42），恶性组SWV平均值（6.37±1.96） m/s显著大于良性组（3.38±1.27） m/s，且差异均有统计学意义（P＜0.05)。VTIQ技术SWV值诊断乳腺实性小结节良恶性的截断值为4.58 m/s。BI-RADS分类、VTI及VTIQ技术ROC曲线下面积（AUC）分别为0.720、0.860、0.924，不同组间两两比较P值均＜0.05，差异均有统计学意义。结论：VTI及VTIQ技术有助于乳腺实性小结节良恶性的评估与鉴别，VTIQ技术在判断乳腺实性小结节的良恶性方面具有更重要的临床应用价值。

Abstract：Objective: To evaluate the application value of virtual touch tissue imaging(VTI) and virtual touch tissue imaging quantification(VTIQ) in differential diagnosis of small solid mammary nodules(diameter ≤10 mm). Methods: A total of 52 patients with 60 small solid mammary nodules from Breast Surgery Department in our hospital all underwent the routine ultrasound examination firstly, and the nodules were classified by BI-RADS. Then the VTI and VTIQ examinations were performed. The hardness scores of nodules were obtained by VTI. The shear wave velocity(SWV) values of nodules were obtained by VTIQ. The ROC curve was drawn to obtain the cut-off value of the small solid mammary nodules by VTIQ by using pathological diagnosis as the gold standard. The diagnostic value of BI-RADS classification, VTI and VTIQ for the benign and malignant small solid mammary nodules was evaluated. Results: The proportion of malignant group of the small solid mammary nodules(16/18) whose VTI hardness score ≥4 was significantly higher than that of the benign group(11/42). The mean SWV of the malignant group (6.37±1.96) m/s was significantly higher than that of the benign group (3.38±1.27) m/s. The difference was statistically significant(P<0.05). The cut-off value of SWV by VTIQ was 4.58 m/s for the diagnosis of small solid mammary nodules. The area under the ROC curve of BI-RADS classification, VTI and VTIQ was 0.720, 0.860, 0.924, respectively. The difference between every two group was statistically significant(P<0.05). Conclusions: VTI and VTIQ conduce to evaluate and differentiate small solid mammary nodules. VTIQ has more important clinical application value in judging the benignity and malignity of small solid mammary nodules.
