Abstract
Objective: To validate the application value of Chinese version TIRADS (C-TIRADS) for thyroid nodules by comparing with the American College of Radiology (ACR) Thyroid Imaging Reporting and Data System (TIRADS), and to explore the diagnostic value of C-TIRADS combined with shear wave elastography (SWE) for benign and malignant thyroid nodules. Methods: A retrospective analysis was performed on 90 patients (90 nodules) with thyroid nodules who underwent ultrasonography and obtained clear pathological results in Qinhuangdao Second Hospital from January 2019 to December 2021. According to the classification rules of C-TIRADS and ACR-TIRADS, the malignant rate of each risk stratification in each system was calculated with pathological results as the gold standard. The diagnostic efficacy of the 2 systems was compared, and the diagnostic efficacy of C-TIRADS combined with SWE for benign and malignant thyroid nodules was analyzed. Results: Among the 90 thyroid nodules, 43 were benign and 47 were malignant. The internal comparison of the actual malignant rate under the risk stratification level of C-TIRADS and ACR-TIRADS was statistically significant (P<0.05). The higher the classification level, the higher the malignant rate. The area under the curve of C-TIRADS and ACR-TIRADS in the diagnosis of thyroid nodules was 0.807 (95%CI 0.710 to 0.882) and 0.765 (95%CI 0.664 to 0.848), and the difference was not statistically significant (P>0.05). The sensitivity of C-TIRADS was lower than that of ACR-TIRADS (78.7% vs 93.6%), and the specificity was higher than that of ACR-TIRADS (72.1% vs 58.1%). The sensitivity of C-TIRADS combined with SWE diagnosis was 95.7%, and the specificity was 72.1%, which was higher than that of single C-TIRADS diagnosis (P<0.05). Conclusion: The efficacy of C-TIRADS in the differential diagnosis of benign and malignant thyroid nodules is close to that of ACR-TIRAD, and it has higher specificity, which helps to reduce unnecessary puncture. The combination of SWE can further improve the diagnostic efficiency and provide better guidance for clinical decision-making.
