Qué hace esta calculadora
Scores thyroid nodule composition, echogenicity, shape, margin, and echogenic foci.
Select one finding in each ACR feature group and enter nodule size to produce the total points and TI-RADS category.
Antes del cálculo
- Use a dedicated thyroid ultrasound and identify composition, echogenicity, shape, margin, echogenic foci, and maximum diameter.
- Check whether the nodule has been biopsied, treated, or previously measured and whether multiple nodules change the reporting plan.
Alcance clínico
Use ACR TI-RADS for sonographic risk stratification of thyroid nodules. It scores five feature groups and uses nodule size with the resulting category to guide follow-up or fine-needle aspiration thresholds.
Aplicabilidad y exclusiones
- The calculator is not intended for non-thyroid neck masses or findings described only on CT, MRI, or PET.
- Previously biopsied or treated nodules and clinically high-risk scenarios require correlation with pathology and clinical history.
Método y lógica de cálculo
Add points for composition, echogenicity, shape, margin, and echogenic foci. The sum determines TR1-TR5; maximum diameter is then used for size-based management thresholds.
Tabla de interpretación
| Points | Category | General interpretation |
|---|---|---|
| 0 | TR1 | Benign |
| 2 | TR2 | Not suspicious |
| 3 | TR3 | Mildly suspicious |
| 4-6 | TR4 | Moderately suspicious |
| 7 or more | TR5 | Highly suspicious |
Errores frecuentes
- Scoring a non-thyroid mass or a nodule described only on CT, MRI, or PET.
- Reporting a TR category without applying the category-specific size threshold for follow-up or FNA.
ACR TI-RADS estimates sonographic risk and size-based next steps; it is not a pathology result.
Ejemplo práctico
Caso: Fictional example: a 1.2 cm solid, hypoechoic, wider-than-tall thyroid nodule with smooth margins and no echogenic foci.
Cálculo: Composition 2 + echogenicity 2 + shape 0 + margin 0 + echogenic foci 0 = 4 points.
Interpretación: The example is TR4. The 1.2 cm size must then be compared with the current ACR follow-up and FNA thresholds.

Preguntas sobre esta calculadora
How is growth defined?
Use the ACR definition and compare measurements in the same planes; apparent small changes may reflect measurement variability.
Should every nodule be reported and followed?
No. Apply the ACR guidance for which nodules to report, follow, or sample, including the approach to multiple nodules.
