Thyroid imaging reporting and data system, abbreviated TIRADS and TI-RADS, is a standardized system for reporting thyroid radiology.[1]

Scoring

ACR TIRADS

The American College of Radiology came out with a TIRADS version that is known as ACR TIRADS in 2017. It is often abbreviated TR.

TR Points Meaning Typical management
TR1 0 points benign
TR2 2 points benign finding(s)
TR3 3 points mildly suspicious for malignancy FNA if lesion >= 2.5 cm; follow-up if lesion >= 1.5 cm
TR4 4 to 6 points moderately suspicious for malignancy FNA if lesion >= 1.5 cm; follow-up if lesion >= 1.0 cm
TR5 7 or more points highly suspicious for malignancy FNA if lesion >= 1.0 cm; follow-up if lesion >= 0.5 cm


"Original" TIRADS

The scoring is broadly similar to the BI-RADS and consists of six possible categorizations:[2]

Score Meaning Typical management
0 incomplete come back for more imaging
1 negative
2 benign finding(s)
3 probably benign often short follow-up
4 ‡ suspicious abnormality needs biopsy
5 highly suggestive of malignancy biopsy to confirm impression
6 pathologist says there is a malignancy excision

Notes:

  • ‡ Category 4 has been subdivided (see below).[3]
  • There is a French TIRADS with five categories.[3]

Subdivision of score 4

Category 4 has been subdivided as per Kwak et al.:[3]

Score Definition Risk of malignancy
4a one suspicious feature 3.3%
4b two suspicious features 9.2%
4c three or four suspicious features 44.4-72.4%
