ACR TI-RADS recommendations
TR5 (≥7 points) - FNA if ≥ 1cm, follow-up annually if ≥ 0.5 cm
TR4 (4-6 points) - FNA if ≥ 1.5 cm, follow-up at 1, 2, 3, and 5 years if ≥ 1.0 cm
TR3 (3 points)- FNA if ≥ 2.5cm, follow-up at 1, 3, and 5 years if ≥ 1.5 cm
TR2 (2 points) & TR1 (0 points) - No FNA or follow-up

* ACR TI-RADS recommends that no more than two nodules with the highest ACR TI-RADS total point should be biopsied and no more than four nodules should be followed.

** TI-RADS recommendations are based on TI-RADS level. Management decisions such as whether to perform FNA and whether to follow up a nodule may differ from the TI-RADS recommendation based on clinician judgement, patient preference, risk factors for thyroid cancer, comorbidities, life expectancy and other considerations.`;
