ACR TI-RADS Recommendation: _____________________________________________

TI-RADS 1 (0 points): Benign- No FNA indication

TI-RADS 2 (2 points): Not suspicious- No FNA indicated

TI-RADS 3 (3 points): Mildly suspicious- FNA is > or = 2.5 cm, follow if > or = 1.5 cm

TI-RADS 4 (4-6 points): Moderately suspicious- FNA if > or = 1.5 or follow if > or = 1.0 cm

TI-RADS 5 (7 or more points): Highly suspicious- FNA if >=1.0 cm, follow if >=0.5 cm

NOTE: The TI-RADS classification of thyroid nodules has been adopted to standardize risk stratification based on a common lexicon to inform practitioners about which nodules warrant biopsy.
