摘要：

目的 探讨不同医师采用甲状腺影像报告和数据系统（TI-RADS）描述词评估不同大小甲状腺结节的观察者间变异。方法 回顾性分析225例甲状腺结节患者的图像，按结节大小分为≤1.0 cm组和＞1.0 cm组，采用Cohen's Kappa检验分析观察者间一致性水平。结果 TI-RADS描述词中形态、内部结构和钙化均有较好的一致性，回声均匀性、后方回声变化和血管模式均为中度一致，以上特征两组一致性水平相同。内部结构、回声均匀性、钙化和后方回声变化的κ值均为≤1.0 cm组较高，形态和血管模式的κ值均为＞1.0 cm组较高。弹性评分的判定均为中度一致，且两组κ值相同。边界和内部回声水平≤1.0 cm组为中度一致，＞1.0 cm组为一致性好。边缘≤1.0 cm组一致性弱，＞1.0 cm组一致性好；分类合并后一致性均有提高。结论 TI-RADS描述词不同医师观察者间的变异多较为理想，部分描述词在不同大小结节有一定差异。

Abstract:

Objective To evaluate the interobserver variability in the thyroid imaging reporting and data system (TI-RADS) description of sonographic features of thyroid nodules with different sizes. Methods The retrospective study was conducted on 225 thyroid nodules. All the cases were divided into ≤1.0 cm group and ＞1.0 cm group according to the diameters. Interobserver variability was determined using Cohen's Kappa statistics. Results About the sonographic features of thyroid nodules, the shape, internal content and calcifications exhibited substantial agreement in both groups. There was moderate agreement with regard to echogenicity, posterior
attenuation and vascular pattern in two groups. The kappa values of internal content, echogenicity, calcifications and posterior attenuation were higher in
≤1.0 cm group, while those of shape and vascular pattern were higher in ＞1.0 cm group. Of the elastography, there was also moderate agreement, and in
particularly the kappa values were equal. There was moderate agreement on boundary and echotexture in ≤1.0 cm group, while there was substantial agreement
in ＞1.0 cm group. There was fair agreement on margin in ≤1.0 cm group, and there was substantial agreement in ＞1.0 cm group. Conclusion There are higher
interobserver agreement on the TI-RADS description of sonographic features of thyroid nodules, and there are differences in some description between
different sizes of thyroid nodules.
