Siriraj Thyroid Imaging Reporting and Data System and Its Efficacy

Abstract

Objective: To standardize a modified practical thyroid imaging reporting and data system (Siriraj-TIRADS). Methods: 196 thyroid nodules underwent ultrasound and FNAB and were retrospectively pathologically proven. Data design was divided into 2 groups of benign and malignant. Sensitivity and specificity of cancer prediction were calculated for the comparison of Siriraj-TIRAD and TIRAD. Interobserver agreement was calculated by kappa statistics. Results: Sensitivity and specificity of Siriraj’s TIRADS on cancer prediction were 95% and 64.8%, respectively, and sensitivity and specificity of TIRADS were 45% and 92%, respectively. Conclusion: The Siriraj- TIRADS classification is easy, practical and has better sensitivity than TIRADS for the diagnosis of thyroid carcinoma. TIRADS is good for the screening management strategy but Siriraj-TIRADS has benefit to cancer management strategy.
