摘要目的评估超声弹性成像在甲状腺TI-RADS4类结节良恶性诊断中的应用价值。方法选取2017年10月—2020年3月在辽宁省人民医院就诊行甲状腺超声检查的93 例患者（108 个甲状腺TI-RADS4类结节）作为研究对象，以病理诊断为金标准，比较TI-RADS、超声弹性成像对甲状腺TI-RADS4类结节良恶性诊断的灵敏度、特异度、准确度、阳性预测值、阴性预测值，绘制ROC 曲线，评估各诊断方法的应用价值。结果单独应用超声弹性成像诊断甲状腺结节的灵敏度、特异度、准确度、阳性预测值、阴性预测值分别为80.88%、75.00%、78.70%、84.61%及69.77%。TI-RADS 诊断系统的灵敏度、特异度、准确度、阳性预测值、阴性预测值分别为77.94%、55.00%、74.65%、59.46%及69.44%。TI-RADS 分类与超声弹性成像联合诊断甲状腺结节的效能高于两者单独应用。结论 TI-RADS联合应用超声弹性成像在甲状腺TI-RADS4类结节良恶性诊断中具有较高价值。

Abstract：Objective To evaluate the application value of ultrasound elastography in the differential diagnosis of benign and malignant TI-RADS4 thyroid nodules.Methods A total of 93 patients(108 thyroid TI-RADS4 nodules)who were performed thyroid ultrasound examination in the People′s Hospital of Liaoning Province from October 2017 to March 2020 were selected as the research subjects.The pathological diagnosis was taken as the golden standard.The sensitivity,specificity,accuracy,positive predictive value and negative predictive value of single application of TIRADS,ultrasonic elastography and combined application of the two for differential diagnosis of benign and malignant thyroid TI-RADS4 nodules were compared,and ROC curves were constructed to evaluate the value of each diagnostic method.Results The sensitivity,specificity,accuracy,positive predictive value and negative predictive value of single application of ultrasonic elastography to diagnose thyroid nodule were 80.88%,75.00%,78.70%,84.61% and 69.77%,respectively.The sensitivity,specificity,accuracy,positive predictive value and negative predictive value of TI-RADS diagnostic system were 77.94%,55.00%,74.65%,59.46% and 69.44%,respectively.The efficacy of TI-RADS classification combined with ultrasound elastography in diagnosis of thyroid nodules was higher than that of the two applications alone.Conclusion TI-RADS combined with ultrasound elastography has a high value in the diagnosis of benign and malignant thyroid TI-RADS4 nodules.
