摘　　要：目的探讨2020甲状腺结节超声恶性危险分层中国指南(C-TIRADS)及其联合弹性成像技术对甲状腺结节的诊断价值。方法回顾性分析经手术病理证实的117例甲状腺结节灰阶及弹性声像图特征,运用C-TIRADS对灰阶声像图进行分类评价,记录超声弹性评估结果,在C-TIRADS结果基础上综合弹性成像对甲状腺结节进行联合诊断。以病理结果为金标准,对比C-TIRADS及联合诊断对甲状腺结节诊断效能。结果C-TIRADS及联合诊断对甲状腺结节诊断敏感性、特异性、准确性、AUC为82.2%、88.6%、84.6%、0.854及95.9%、86.4%、92.3%、0.911。联合诊断较C-TIRADS单独运用敏感性、准确性、AUC上升,特异性略有下降(P<0.05)。结论C-TIRADS对甲状腺结节具有较好的诊断价值,在此基础上联合弹性成像可进一步提升超声诊断价值。Objective To investigate the value of 2020 Chinese guidelines for ultrasound malignancy risk stratification of thyroid nodules(Chinese thyroid imaging reporting and data system,C-TIRADS)and the combination with elastography technology in the diagnosis of thyroid nodules.Methods The gray-scale and elastic sonographic features of 117 thyroid nodules confirmed by postoperative pathological diagnosed were analyzed retrospectively.C-TIRADS was used to classify and evaluate the gray-scale image,the ultrasonic elastic characteristics combined with the C-TIRADS results to establish a joint diagnosis of thyroid nodules.Based on related pathological data,the diagnostic value of C-TIRADS and the joint diagnosis for thyroid nodule was statistically compared.Results The sensitivity,specificity,accuracy and AUC of C-TIRADS and the joint diagnosis for diagnosing thyroid nodules were 82.2%,88.6%,84.6%,0.854 and 95.9%,86.4%,92.3%,0.911.Compared with C-TIRADS alone,there were consistent elevations of the sensitivity,accuracy and AUC in the joint diagnosis,while the specificity slightly decreased(P<0.05).Conclusion C-TIRADS have a satisfied diagnostic value for thyroid nodules.The joint diagnosis by combining with elastography can further enhance ultrasound diagnosis.
