The American College of Radiology Thyroid Imaging Reporting and Data System (ACR TI-RADS) standardizes ultrasound evaluation, aiding malignancy risk stratification and reducing unnecessary biopsies. Methods This retrospective study analyzed 182 patients who underwent thyroid ultrasound and FNA between August 2023 and August 2024. Nodules were classified using the ACR TI-RADS and Bethesda systems. Chi-square and receiver operating characteristic (ROC) curve analyses assessed correlations between classifications. Results The mean age was 49.77 years, with 159 females (87.36%) and 23 males (12.64%). Most nodules were categorized as ACR TI-RADS 3 (n = 120, 65.93%) and Bethesda 2 (n = 148, 81.32%), indicating benignity. Higher ACR TI-RADS scores correlated with increased malignancy risk, with ACR TI-RADS 5 nodules (n = 5, 2.75%) aligning with Bethesda 5 (n = 5, 2.75%). ROC analysis showed an area under the curve (AUC) of 0.93 for malignancy detection, demonstrating strong discriminatory power. Conclusion ACR TI-RADS aligns well with Bethesda results, effectively stratifying thyroid nodule risk and reducing unnecessary interventions.}, number={5}, publisher={Selcuk University}
