Exploring the Application Value of C-TIRADS Classification and ACR-TIRADS Classification in the Diagnosis of Hashimoto Nodules and Papillary Thyroid Carcinoma in the Context of Hashimoto's Thyroiditis
Objective:To explore the application value of Chinese Thyroid Imaging Reporting and Data System(C-TIRADS)and American College of Radiology Thyroid Imaging,Reporting and Data Sys-tem(ACR-TIRADS)classifications in the diagnosis of Hashimoto's nodules and papillary thyroid carci-noma(PTC)in the context of Hashimoto's thyroiditis in China.Methods:72 patients admitted to the First People's Hospital of Huizhou from January 2021 to January 2023 were selected.These patients had a to-tal of 134 nodules,including Hashimoto's nodules and PTC,which were evaluated using ultrasound.Post-operative pathological examination was used as the gold standard.The nodules were divided into Hashi-moto's thyroiditis(HT)group(25 cases,38 nodules)and PTC group(47 cases,96 nodules).The imaging manifestations of the two groups were compared,,focusing on the differences in ultrasonic characteristics and the diagnostic accuracy of C-TIRADS and ACR-TIRADS classifications.Results:HT nodules typi-cally exhibited unclear boundaries,irregular edges,high/equal echogenicity,and absence of focal strong echogenicity,while PTC nodules often showed irregular and unclear edges,low echogenicity,and micro-calcifications.There were no statistically significant differences in the aspect ratio and internal structure between the two groups of patients in terms of ultrasound characteristics(P＞0.05),but there were statisti-cally significant differences in edge,echo,calcification,and acoustic halo(P＜0.05).C-TIRADS catego-ries TR3,TR4,and TR5 demonstrated malignancy rates of 14.29％,18.18％,and 98.90％,respectively,while ACR-TIRADS categories 4B,4C,and 5 had malignancy rates of 43.33％,89.19％,and 98.00％,re-spectively.The difference in diagnostic accuracy between the two systems was statistically significant(P＜0.05).Conclusion:The ACR-TIRADS grading method is more complex in diagnosis of Hashimoto nod-ules and papillary thyroid carcinoma,while the C-TIRADS grading method is more convenient and closer to clinical practice.
