目的 评估甲状腺超声影像数据和报告系统(TI-RADS)分级、超声弹性应变率(SR)及声触诊组织定量技术(VTQ)3种方法诊断甲状腺结节良恶性的价值.方法 选取需手术治疗的甲状腺结节患者128例,术前对所有甲状腺结节进行二维及彩色多普勒超声检查并用TI-RADS分级;以同侧胸锁乳突肌为参照物测量甲状腺结节的SR值;进行 VTQ分析并记录甲状腺结节的剪切波速度.以手术病理为金标准,应用受试者工作特征(ROC)曲线评估TI-RADS、SR值及VTQ判断甲状腺结节良恶性的准确性.结果 甲状腺良、恶性结节的TI-RADS分级、SR值及VTQ比较,差异有统计学意义(P<0. 05),ROC曲线下面积分别为0. 83、0. 87、 0.92.结论 VTQ技术可提高超声对甲状腺结节良恶性判断的准确性.%Objective To explore the value of ultrsound tyorid imaige reporing and systerm (TI-RADS ), ultrasonic elastic strain rate (SR) and virtual touch tissue quantification (VTQ) three methods diagnosis of benign and malignant thyroid nodule. Methods 128 patients with thyroid nodule which need surgical treatment were selected as research objective. Before surgical treatment, all thyroid nodules detection with two-dimensional and color doppler ultrasoundand and classification by TI-RADS; All thyroid nodules measuring the SR of thyroid nodule as referenced of sternocleidomastoid; All thyroid nodules conducted with VTQ detection and recorded by shear wave velocity. Receiver operator characteristic curve (ROC) was used to evaluate TI-RADS, SR and VTQ in identifying benign and malignant thyroid nodule which by surgery pathology as the gold standard. Results TI-RADS, SR and VTQ had statistically significant (P < 0. 05 ) in benign and malignant thyroid nodules, the area under the ROC curve of TI-RADS, SR and VTQ were respectively 0. 83, 0. 87, 0. 92. Conclusion VTQ could improve the accuracy of ultrasonography in identifying benign and malignant thyroid nodule.
