Understanding TI-RADS Assessment
What is TI-RADS?
The Thyroid Imaging Reporting and Data System (TI-RADS) is a standardized scoring system developed by the American College of Radiology (ACR) to assess thyroid nodules found during ultrasound examination. It helps determine the risk of malignancy and guides management decisions.
How It Works
TI-RADS evaluates five ultrasound features of thyroid nodules, assigning points based on suspicious characteristics. The total score determines the TI-RADS category (TR1-TR5) and provides recommendations for fine needle aspiration (FNA) and follow-up.
Clinical Applications
- •Standardizes thyroid nodule reporting
- •Guides FNA biopsy decisions
- •Determines follow-up schedules
- •Reduces unnecessary biopsies
- •Improves patient management
Important Considerations
- ⚠Multiple nodules should be assessed individually
- ⚠Size measurements are crucial for management
- ⚠Clinical correlation is always necessary

Thyroid nodule assessment requires proper ultrasound interpretation by qualified healthcare professionals. Always consult with an endocrinologist or radiologist for proper evaluation and management of thyroid nodules.
The TI-RADS score is one tool among many in thyroid nodule evaluation. Clinical history, physical examination, and other factors must also be considered in patient management.
