In the Thyroid worksheet, the TI-RADS (Thyroid Imaging Reporting and Database System) field is calculated automatically. These calculated values automatically update when any of the source values are changed. These values align with ACR TI-RADS documentation. The TI-RADS score is the sum of the points associated with the description of a nodule.
Composition
| Description | Points |
|---|---|
| Cystic or almost completely cystic | 0 |
| Spongiform | 0 |
| Mixed cystic and solid | 1 |
| Solid or almost completely solid | 2 |
Choose one. Assign two points if the composition cannot be determined because of calcification.
Echogenicity
| Description | Points |
|---|---|
| Anechoic | 0 |
| Hyperechoic or Isechoic | 1 |
| Hypoechoic | 2 |
| Very Hypoechoic | 3 |
Choose one. Add one point if the echogenicity cannot be determined.
Shape
| Description | Points |
|---|---|
| Wider-than-tall | 0 |
| Taller-than-wide | 3 |
Choose one.
Margin
| Description | Points |
|---|---|
| Smooth | 0 |
| Ill-Defined | 0 |
| Lobulated or irregular | 2 |
| Extra-thyroidal extension | 3 |
Choose one. Assign zero points if the margin cannot be determined.
Echogenic Foci
| Description | Points |
|---|---|
| None or large comet-tail artifacts | 0 |
| Macrocalcifications | 1 |
| Peripheral (rim) calcifications | 2 |
| Punctuate echogenic foci | 3 |
Choose all that apply.
Calculated Fields
These calculated values automatically update when any of the source values are changed.
| Field | Source Values | Calculation Logic |

| TI-RADS | Composition, Echogenicity, Shape, Margin, Echogenic Foci | Composition points + Echogenicity points+ Shape points + Margin points + Echogenic Foci points |
TI-RADS Levels
| Level | Point Total | Description |

| TR1 | 0 | Benign |
| TR2 | 2 | Not suspicious |
| TR3 | 3 | Mildly suspicious |
| TR4 | 4-6 | Moderately suspicious |
| TR5 | 7 or more | Highly suspicious |
