Adjusted Risk Stratification of Indeterminate Thyroid Nodules Using the American College of Radiology Thyroid Imaging Reporting and Data System (ACR TI‐RADS)
ABSTRACT Background The TI‐RADS guides the initial management of thyroid nodules, but the malignancy risk across different categories of cytologically indeterminate thyroid nodules (CITNs), particularly AUS and FN, remains unclear. Methods We reviewed thyroid FNA specimens diagnosed as AUS or FN with TI‐RADS scores of 3, 4, or 5 from 2017 to 2025. Clinical data, molecular results, and surgical outcomes were analyzed. Results A total of 919 CITNs were identified: 304 with TI‐RADS 3, 454 with TI‐RADS 4, and 161 with …
