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

Scoring

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%
