Thyroid imaging reporting and data system, abbreviated TIRADS and TI-RADS, is a standardized system for reporting thyroid radiology.[1]
ACR TIRADS
The American College of Radiology (abbreviated ACR) came out with a TIRADS version that is known as ACR TIRADS in 2017.[citation needed] It is often abbreviated TR.
| ACR TIRADS | Points | Meaning | 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 original TIRADS is broadly similar to 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:
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% |
