| 目的 探讨声触诊组织量化（VTQ）成像技术对甲状腺影像报告和数据系统（TI-RADs）4类结节的良恶性鉴别诊断价值。方法 对88个常规超声评价为TI-RADs 4类的甲状腺结节行VTQ检查。比较VTQ与TI-RADs分类的诊断效能。结果 88个TI-RADs 4类甲状腺结节中，良性结节56个，恶性结节32个。以TI-RADs 4b类和4c类诊断为恶性结节，其诊断敏感度、特异度、阳性预测值、阴性预测值及准确率分别为90.63%（29/32）、57.14%（32/56）、54.72%（29/53）、91.43%（32/35）及69.32%（61/88）。甲状腺恶性结节VTQ值[（3.26±0.94）m/s]明显高于良性结节VTQ值[（2.03±0.61）m/s，t=7.082，P < 0.001]。VTQ的最佳诊断界值为2.795 m/s，其诊断甲状腺结节良恶性的敏感度、特异度、阳性预测值、阴性预测值及准确率分别为78.13%（25/32）、91.07%（51/56）、83.33%（25/30）、87.93%（51/58）及86.36%（76/88）。VTQ值诊断TI-RADs 4类甲状腺结节良恶性的特异度及阳性预测值明显高于TI-RADs分类（P均< 0.05）。结论 VTQ技术有助于TI-RADs 4类甲状腺结节的良恶性鉴别诊断，值得临床推广。 |

| Objective To explore the value of virtual touch tissue quantification (VTQ) imaging in differential diagnosis of thyroid imaging report and data system (TI-RADs) 4 thyroid nodules. Methods Eighty-eight thyroid nodules identified as TI-RADs 4 using conventional ultrasound underwent VTQ examinations. The diagnostic efficiencies of VTQ value and TI-RADs were compared. Results Among 88 TI-RADs 4 thyroid nodules, there were 56 benign and 32 malignant nodules. Taken TI-RADs 4b and 4c as malignant, the diagnostic sensitivity, specificity, positive predictive value, negative predictive value and accuracy was 90.63%(29/32), 57.14%(32/56), 54.72%(29/53), 91.43%(32/35) and 69.32% (61/88), respectively. VTQ values of malignant nodules were significantly higher than that of benign nodules ([3.26±0.94] m/s vs[2.03±0.61] m/s, t=7.082, P < 0.001). Taken VTQ=2.795 m/s as the cut-off point, the sensitivity, specificity, positive predictive value, negative predictive value and accuracy in differential diagnosis of malignant and benign thyroid nodules was 78.13%(25/32), 91.07%(51/56), 83.33%(25/30), 87.93%(51/58) and 86.36%(76/88), respectively. The specificity and positive predictive value of VTQ value were significantly higher than those of TI-RADs (both P < 0.05). Conclusion VTQ was helpful to differential diagnosis of TI-RADs 4 thyroid nodules and worthy of clinical application. |
