Abstract:
Objective:To validate the Chinese version of Thyroid Imaging Report and Data System (C-TIRADS) for the malignancy risk stratification assessment of thyroid nodules, and compare with the American College of Radiology TIRADS(ACR-TIRADS) for diagnostic performance.Methods:A total of 1 306 patients with 1 389 thyroid nodules in the First Affiliated Hospital of Hainan Medical University from January 2015 to March 2021 were reviewed and assessed for diagnostic performance according to the C-TIRADS and the ACR-TIRADS, respectively, and the histopathological results were taken as golden standard.Results:The 1 389 thyroid nodules consisted of 973 benign nodules and 416 malignant nodules. The C-TIRADS 4C and ACR-TIRADS 5 had the highest accuracies and were taken respectively as the optimized cut-off values for diagnosis.The sensitivity, specificity, positive and negative predictive values and AUC by C-TIRADS 4C and ACR-TIRADS 5 for thyroid nodule evaluation were 87.39%, 89.92%, 75.00%, 95.38%, 0.89, and 85.58%, 91.88%, 81.84%, 93.71%, 0.89, respectively(all P>0.05). Conclusions:The C-TIRADS and ACR-TIRADS have good diagnostic performance for the malignancy risk stratification of thyroid nodules, and C-TIRADS 4C has comparable diagnostic performance to ACR-TIRADS 5.
