Overview

Comparative study reveals ACR TIRADS reduces unnecessary fine-needle biopsies in thyroid nodule patients, suggesting enhanced specificity over ATA criteria.

Key Points

  • To validate and compare the diagnostic performance and biopsy-sparing efficiency of ACR TIRADS versus ATA risk stratification guidelines in patients with thyroid nodules.
  • Analyzed 281 thyroid nodules in 245 patients undergoing ultrasound-guided fine-needle aspiration biopsy (FNAB) between May 2018 and June 2019.
  • Evaluated 235 nodules that met criteria for FNAB under ACR TIRADS and/or ATA systems, correlating imaging features with Bethesda scoring cytology.
  • ACR TIRADS and ATA guidelines showed concordance in 58.2% (137/235) of cases, whereas ATA recommended biopsy in 35.3% (83/235) where TIRADS did not.
  • Specificity was 37% (81/221) for ACR TIRADS compared to 7% (15/221) for ATA criteria.
  • Sensitivity was 86% (12/14) for ACR TIRADS compared to 100% (14/14) for ATA criteria, reducing benign nodule biopsies by 35% at the expense of two missed carcinomas managed via follow-up.
