Thyroid Imaging Reporting & Data System (TI-RADS™) 

TIRADSthyroid_320Thyroid nodules are exceedingly common, leading to costly interventions for many lesions that ultimately prove benign.

In response, ACR committees were formed to accomplish three goals:

  1. Develop management guidelines for nodules that are discovered incidentally on CT, MRI, PET or ultrasound.
  2. Produce a lexicon to describe all thyroid nodules on sonography.
  3. Develop a standardized TI-RADS risk-stratification system based on the lexicon to inform practitioners about which nodules warrant biopsy.
