Easy TI-RADS Calculator with Example Cases

The TI-RADS Calculator is an essential tool for evaluating thyroid nodules using the Thyroid Imaging Reporting and Data System (TI-RADS). This standardized approach helps determine malignancy risk based on ultrasound characteristics, providing evidence-based recommendations for follow-up and fine-needle aspiration (FNA) decisions.

Our Easy TI-RADS Calculator simplifies this complex scoring system into an intuitive, visual interface that guides you through each characteristic assessment with real ultrasound examples. Whether you’re a radiologist, endocrinologist, or sonographer, this tool ensures consistent, accurate TI-RADS scoring following the 2017 ACR guidelines.

How to Use the TI-RADS Calculator?

1. Select the best option for each characteristic based on the ultrasound images. For Echogenic Foci, you may select multiple options if present.
2. Click “Calculate TI-RADS Score” when all selections are complete.
3. Review your results: Score, risk category, and clinical recommendations.
   • TI-RADS Score (0-10 points) with risk category (TR1-TR5)
   • Evidence-based recommendations for follow-up and FNA decisions
   • Score breakdown showing how points were allocated
   • Clinical guidance following 2017 ACR guidelines
