Pandya A, Caoili EM, Jawad-Makki F, et al. - The intent of this study was to correlate diagnostic accuracy and reliability of the 2017 American College of Radiology (ACR) Thyroid Imaging Reporting and Data System (TI-RADS) and 2015 American Thyroid Association (ATA) classifications for thyroid nodules. Between 2007 and 2016, researchers performed a retrospective cohort study including a total of 1,947 consecutive thyroid nodules sampled with fine-needle aspiration (FNA). The TI-RADS scores were assigned to all nodules while blinded to clinical outcome and histologic diagnosis and matched TI-RADS scores with module-specific ATA scores from the same cohort. It was demonstrated that 2017 ACR TI-RADS and 2015 ATA classifications have similar diagnostic accuracies and interrater agreement, but TI-RADS results in fewer nodules being recommended for immediate FNAs and more nodules being recommended for imaging surveillance.
