What Is the TI-RADS Calculator?
The TI-RADS (Thyroid Imaging Reporting and Data System) is a standardized scoring system developed by the American College of Radiology (ACR) to help sonographers and radiologists assess thyroid nodules consistently. Each ultrasound feature—such as composition, echogenicity, shape, margin, and echogenic foci—earns points that combine into an overall TI-RADS score. This score helps estimate the risk of malignancy and guides decisions on biopsy or follow-up.
Our ACR TI-RADS Calculator at SonoCalcLab.com lets you enter these features quickly and automatically see:
The total TI-RADS points
The corresponding TI-RADS category (TR1–TR5)
The estimated likelihood of malignancy
The recommended follow-up interval or FNA (fine-needle aspiration) threshold
No math, no guesswork—just clear results instantly.
How to Use the TI-RADS Calculator
Select each ultrasound feature
Choose the composition (solid, mixed cystic, etc.)
Select echogenicity, shape, margin, and echogenic foci
Each choice automatically adds points according to the ACR guidelines
View your TI-RADS score
The calculator instantly totals your score and displays the category (TR1–TR5).Interpret the results
TR1–TR2: Benign or not suspicious
TR3: Mildly suspicious (follow-up if ≥1.5 cm)
TR4: Moderately suspicious (consider FNA if ≥1.5 cm)
TR5: Highly suspicious (FNA if ≥1 cm)
Follow recommended management
The calculator also displays the recommended ultrasound follow-up intervals (e.g., 1, 3 and 5 years for TR3 nodules > 1.5 cm).
You can use this tool directly in your reporting workflow or as a double-check while documenting thyroid findings.
Why TI-RADS Scoring Matters
Before the ACR introduced TI-RADS, thyroid ultrasound interpretation varied widely between practitioners. By adopting this system:
Radiologists and sonographers speak the same language when describing nodules.
Patients receive consistent, evidence-based care.
Clinics reduce unnecessary biopsies and focus on nodules that truly need follow-up.
Using an online calculator ensures accuracy, speed, and reproducibility—especially when you’re scanning a high volume of patients or training new staff.
Bonus: Simplify Your Workflow
At SonoCalc Lab, the goal is to make radiology tools simple, reliable, and fast. The TI-RADS calculator saves time, standardizes reporting, and reduces error risk.
