Utility of ACR TI‐RADS to determine need for repeat FNA in thyroid nodules with nondiagnostic cytology

Key Points

• This research aims to evaluate the necessity of repeat fine-needle aspiration (FNA) for thyroid nodules classified as B1 with nondiagnostic cytology.
• Analyzed TI-RADS classifications of thyroid nodules
• Categorized B1 nodules into TI-RADS 1-5
• Assessed malignancy risks associated with each category
• B1 nodules in TI-RADS 1-3 show low malignancy risk and may not need repeat biopsy
• B1 nodules in TI-RADS 4 and 5 have a higher malignancy risk and should undergo repeat biopsy
