中文摘要:
      目的 比较声触诊组织成像定量技术（VTIQ）与声触诊定量技术（VTQ）对BI-RADS 3~5类乳腺肿瘤的鉴别诊断价值 方法 选取经手术病理证实的BI-RADS 3~5类乳腺肿瘤患者60例，根据术后病理结果分为良性组与恶性组，分别以术前VTQ及VTIQ弹性成像检查所获取的病灶剪切波速度（SWV）作为观察指标，采用受试者工作曲线（ROC）分析评估两种技术的诊断效能。结果 共纳入乳腺肿瘤60个，其中良性肿瘤33个，恶性肿瘤27个。VTIQ与VTQ检查成功率分别为100% 与 86.67%（P＜0.01)。采用VTIQ检查，良、恶性组SWV均值为（3.79±0.87）m/s与（5.40±0.81）m/s（P＜0.01），以4.29m/s作为鉴别界值，其敏感性92.59%、特异性84.85%；采用VTQ检查，良、恶性组SWV均值为（4.03±0.92）m/s与（4.70±0.72）m/s（P＜0.01），以4.02m/s作为鉴别界值，其敏感性84.21%、特异性69.70%；两者的曲线下面积（AUC）对比提示VTIQ诊断效能优于VTQ（0.892vs0.746）（P<0.01）。结论 两种技术均可用于BI-RADS 3~5类乳腺肿瘤的鉴别诊断，VTIQ技术较VTQ具有更高的诊断效能。
英文摘要:
      Objective To compare the BI-RADS 3~5 category breast lesions diagnostic efficiency by virtual touch tissue imaging quantification (VTIQ) and virtual touch tissue quantification (VTQ) . Methods Sixty patients with BI-RADS 3~5 category breast lesion were recruited and divided into benign or malignant group based on the surgical pathology diagnosis. The shear wave velocity (SWV) measurements with both VTQ and VTIQ were recorded and analyzed.The diagnostic efficiency between VTQ and VTIQ was assessed with ROC curve. Results A total of 60 cases were included (33 benign and 27 malignant cases). The success rate of VTIQ was 100% and VTQ was 86.67% (P<0.01). The mean SWV values of VTIQ in the diagnosis of benign group and malignant group were (3.79±0.87) m/s and (5.40±0.81) m/s, respectively (P<0.01). The cut-off point of VTIQ was 4.29m/s, with the sensitivity of 94.71% and the specificity of 81.81%. The mean SWV values of VTQ in the diagnosis of benign group and malignant group were (4.03±0.92) m/s and (4.70±0.72) m/s, respectively(P<0.01). The cut-off point of VTQ was 4.02m/s,with the sensitivity of 84.20% and the specificity of 69.70%. The area under the curve (AUC) showed that the diagnostic efficiency of VTIQ was better than VTQ(0.892vs 0.746)(P<0.01).Conclusion Both techniques can be used for the differential diagnosis of BI-RADS 3~5 category breast lesions, but the diagnostic efficiency of VTIQ is better than VTQ.
