Abstract:
Objective To investigate the value of TI-RADS for sonographic diagnosis of papillary thyroid carcinoma (PTC) and follicular thyroid carcinoma (FTC) and to evaluate the sonographic findings of FTC compared to PTC.Methods The clinical and sonographic data of 363 cases of pathology confirmed thyroid nodules were retrospectively analyzed.The thyroid nodules were classified by TI-RADS grading criteria,the accuracy of TI-RADS and sonographic findings between FTC and PTC was analyzed.Results In 363 thyroid nodules,114 cases were confirmed as benign lesions;249 cases were confirmed as carcinomas,including 50 FTC cases and 199 PTC cases.The sensitivity,specificity,PPV,NPV,and accuracy of PTC were 97.0％ (193/199),85.1％ (97/114),91.9％ (193/210),85.8％ (97/113),95.7％ (290/303) respectively.The sensitivity,specificity,PPV,NPV,and accuracy of FTC were 97.0％(193/199),85.1％ (97/114),91.9％ (193/210),85.8％ (97/113),95.7％ (290/303) respectively.There were significant differences of nodule size,shape,margin,echogenecity,calcification,halo and flow between FTC group and PTC group (P ＜ 0.05).Conclusion TI-RADS has higher value in the sonographic diagnosis of PTC than that of FTC.FTC are greatly different from PTC in many sonographic findings making it less valuable for the diagnosis of FTC.
