摘　　要：目的探讨声触诊组织成像与定量（Virtul touch tissue imaging quantification,VTIQ）剪切波弹性成像在诊断乳腺良恶性病变中的应用。方法选取2015年10月~2016年1月我院收治的乳腺结节患者68例,其中良性病变40例,恶性病变28例。患者在VTIQ模式下,测量病灶剪切波速度（Shear wave velocity,SWV）值,获取患者的SWV最大值、最小值、平均值。然后根据ROC曲线确定准确性最高的一组SWV值,获取最佳诊断值,并评估诊断效能。结果 68例患者共有病灶96个,其中良性病灶64个,恶性病灶32个,良性病灶SWV最大值为（5.76±0.81）m/s,平均值为（3.01±0.87）m/s,最小值为（1.31±0.90）m/s,恶性病灶SWV最小值（2.85±1.31）m/s,平均值为（5.61±1.49）m/s,最大值为（8.91±1.73）m/s。得到SWV值的截断值为3.51 m/s,曲线下的面积为0.903,它的敏感性、特异性、准确性分别为94.5%、81.4%、86.3%。结论声触诊组织成像与VTIQ剪切波弹性成像技术在诊断乳腺良恶性病变中有重要的作用。Objective To investigate quantitative shear wave elasticity imaging in the diagnosis of benign and malignant breast lesions.Methods 2013 years 9 months to 2015 years 9 months,treated in our hospital breast nodules in patients with a total of 68 cases of benign 40 cases of malignant 28 cases.Patients in VTIQ mode,the measurement focus SWV value gets with SWV maximum,minimum,and average.According to ROC curve to determine the accuracy of the highest group SWV,obtain the best diagnostic value and to assess the diagnostic performance.Results 68 patients with diagnosis,benign 64 cases of malignant lesions 32 cases of benign SWV maximum value is（5.76±0.81）m/s,the average is（3.01±0.87）m/s,Minimum value of（1.31±0.90）m/s Malignant lesions SWV Minimum value of（2.65±1.31）m/s Average of（5.11±1.49）m/s,Maximum（8.91±1.73）m/s,Get SWV The truncated value for value 3.51m/s And area under the curve for the 0.903.Its sensitivity,specificity,accuracy,respectively 94.5%、81.4%、86.3%。Conclusion Quantitative（VTIQ）shear wave elasticity imaging techniques in the diagnosis of benign and malignant breast lesions in its important role,it is worth promoting.
