Objective To compare and analyze the value of Chinese thyroid imaging reporting and data system(C-TIRADS)and Korean-TIRADS(K-TIRADS)in differential diagnosis of benign and malignant thyroid nodules.Methods We retrospectively analyzed the ultrasonic images of 582 thyroid nodules confirmed by histopathology in Qingdao University Affiliated Tai'an Central Hospital from March 2017 to March 2023.The nodules were classified according to C-TIRADS and K-TIRADS criteria,respectively.The diagnostic efficacy of the two methods was analyzed with pathological results as the gold standard.Results The actual malignancy rate of thyroid nodules stratified by the two methods obtained was consistent with the malignancy rate recommended by the guidelines.The area under the curve of C-TIRADS and K-TIRADS were 0.899 and 0.897 respectively,and there was no significant difference between them.The best cut-offvalue of C-TIRADS was 4B,and that of K-TIRADS was 5.The sensitivity and specificity of the two were 0.925,0.872,0.818 and 0.889,respectively.Conclusion Both C-TIRADS and K-TIRADS have high value in differential diagnosis of benign and malignant thyroid nodules with equivalent diagnostic efficacy.C-TIRADS is more suitable for China's national conditions.
