摘　　要：目的探讨声脉冲辐射力（ARFI）弹性成像在乳腺肿块鉴别诊断中的价值。方法分别应用ARFI弹性成像的声触诊组织定性成像（VTI）和声触诊组织定量（VTQ）技术判断肿块的性质、范围和检测肿块的横向剪切波速度（SWV）。结果乳腺癌和良性病变的SWV值分别为（7．84±2．51）m／s和（2．79±0．92）m／s。乳腺良恶性病灶的SWV值差异有统计学意义（P〈0．01）。病灶的SWV值用于鉴别乳腺病变的良恶性，受试者工作特征曲线的曲线下面积为0．886。以SWV4．4为诊断临界值，判断乳腺肿物良恶性的敏感性、特异性、准确性、阳性预测值、阴性预测值分别为78．7％、100％、91．7％、100％、88％。结论ARFI可反映乳腺肿块的弹性特征，对乳腺良、恶性肿块具有鉴别诊断价值。Objective To investigate the value of acoustic radiation force impulse （ARFI） in dif- ferential diagnosis between benign and malignant breast tumors. Methods Virtual touch tissue imaging （VTI） and virtual touch tissue quantification （VTQ） of ARF! Elastography were used to estimate the prop- erties and extent and measured the shear wave velocities （SWV） of the breast tumors, respectively. Results The mean SWV of breast cancer and benign lesion were （ 7. 84 ±2. 51 ） m/s and （2.79± 0. 92 ） m/s. There was significant difference in the SWV between benign and malignant breast tumors （ P 〈 0. 01 ）. The area under curve （AUC） of receiver operating characteristic （ROC） curve of the SWV in differentiating be- nign from malignant breast tumors was 0. 886. With SWV 4. 4 as cut-off, the sensitivity, specificity, accu- racy, positive predictive value and negative predictive value in the diagnosis of malignant from benign breast tumors were 78.7%, 100%, 91.7%, 100%, 88%, respectively. Conclusions ARFI elastography could reflect the elastic characteristics of breast tumors, which might be useful for the differential diagnosis be- tween benign and malignant breast tumors.
