Thyroid Imaging Reporting & Data System 

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

In response, ACR formed a committee with 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

The first two phases are complete and have been published below. Work on the third phase is well underway.
