MON-LB84 Validation of TI-RADS (Thyroid Imaging, Reporting and Data System) Follow-Up Recommendations

Background:Thyroid nodules are exceedingly common, leading to costly interventions for many lesions that ultimately prove benign. Therefore, a reliable, noninvasive method to identify which nodules warrant fine needle aspiration and/or follow-up on the basis of a reasonable likelihood of malignancy is highly desirable. American College of Radiology (ACR) created a standard terminology (lexicon) to describe all thyroid nodules on sonography and standardized TI-RADS risk-stratification system to identify nodules that warrant biopsy and/or follow-up. Many healthcare institutions including UPMC adapted the TI-RADS scoring system in order to identify most clinically significant malignancies while reducing the number of biopsies and follow-up ultrasounds performed on benign nodules. According to ACR, TI-RADS category 3 nodules
