TIRADS Calculator & Report Generator

Evaluation of thyroid nodules on ultrasound using ACR's Thyroid Imaging Reporting & Data System (TI-RADS ™). This tool features images from ACR's TIRADS atlas, and is now equipped with a report generator!

TI-RADS (report)
1. How is the nodule's composition?
2. How is the nodule’s echogenicity? (Compared to the adjacent parenchyma)
3. How is the nodule's shape?
Note: Nodule's shape should be assessed on a transverse image with measurements parallel to the sound beam for height and perpendicular to the sound beam for width.
4. How are the margins?
5. Are there any additional features? Choose all that apply.
Large comet-tail artifacts = V-shaped, >1mm, in cystic components
Macrocalcifications = cause acoustic shadowing
Peripheral/rim calcifications = along margin, either complete or partial
Punctate echogenic foci = may have small comet-tail artifacts

TIRADS Score:
→ No further follow-up is needed.
→ No further follow-up is needed.
Note: Spongiform, cystic, and almost completely cystic nodules always have a TI-RADS score of 1, irrespective of their other features.
→ No further follow-up is needed.
→ FNA if ≥ 2.5cm
→ Follow-up imaging if ≥ 1.5cm (in 1, 3, and 5 years)
→ FNA if ≥ 1.5cm
→ Follow-up imaging if ≥ 1cm (in 1, 2, 3, and 5 years)
→ FNA if ≥ 1cm
→ Follow-up imaging if ≥ 0.5cm (annually up to five years)
Answer all questions to calculate the final score

The following questions are not necessary for score calculation, but are needed to generate a report:

More about the ACR TIRADS calculator and report generator:

The Thyroid Imaging Reporting and Data System (TIRADS), developed by the American College of Radiology (ACR), is a globally acknowledged framework for evaluating thyroid nodules using ultrasound findings. By standardizing the assessment process, TIRADS ensures consistency, clarity, and accuracy in diagnosing thyroid conditions, enabling better clinical decision-making. While our interactive TIRADS calculator is not officially endorsed by the ACR, it has been carefully crafted to align with the principles of the ACR’s TIRADS system. This free tool offers healthcare professionals a reliable, practical, and user-friendly means to assess thyroid nodules.

Understanding the TIRADS Framework

The ACR TIRADS system provides a structured approach to evaluate thyroid nodules based on ultrasound characteristics, assigning a weighted score to each feature. These features include:

  • Composition: Identifies whether the nodule is cystic, solid, or mixed, as composition significantly affects malignancy risk.
  • Echogenicity: Examines the nodule's brightness compared to the surrounding thyroid tissue, with categories ranging from anechoic to markedly hypoechoic.
  • Shape: Considers whether the nodule’s shape is taller-than-wide, a configuration associated with higher malignancy risk.
  • Margins: Analyzes the borders for irregularities or extrathyroidal extension, both of which are concerning features.
  • Echogenic Foci: Detects calcifications, which may signify varying malignancy risks based on their type (e.g., microcalcifications).

The cumulative score determines the TIRADS category, ranging from TR1 (benign) to TR5 (high suspicion). Each category provides specific recommendations, such as routine follow-up, further imaging, or fine-needle aspiration biopsy (FNAB).

Key Features of the ACR TIRADS Calculator

This interactive tool simplifies the TIRADS scoring process, allowing users to input ultrasound findings and receive instant categorizations. Its features include:

  • Automated Scoring: Eliminates manual calculations, ensuring speed and accuracy in generating TIRADS scores.
  • Integrated Reporting: Provides detailed, easy-to-understand reports to facilitate communication between radiologists, clinicians, and referring physicians.
  • User-Friendly Interface: Intuitive design makes it accessible to healthcare providers across all levels of experience.
Clinical Impact

Adopting the TIRADS framework has revolutionized thyroid nodule evaluation, offering numerous advantages:

  • Standardized Reporting: Promotes consistency across clinicians and institutions, reducing interobserver variability.
  • Enhanced Risk Stratification: Improves the ability to identify high-risk nodules while avoiding unnecessary interventions for benign ones.
  • Efficient Patient Management: Offers evidence-based recommendations for appropriate follow-up, biopsy, or reassurance.
Minimizing Unnecessary Interventions

One of the significant benefits of TIRADS is its ability to reduce unnecessary invasive procedures. By accurately identifying benign nodules, it helps avoid undue biopsies and surgeries, sparing patients from potential risks and anxiety. At the same time, the system ensures timely intervention for nodules with a higher likelihood of malignancy, optimizing patient care.

Evidence-Based Design and Practical Considerations

This calculator is built on the robust scientific foundation of the ACR TIRADS guidelines, adhering to their scoring methodology. While it provides an evidence-based approach to thyroid nodule evaluation, users should consider certain practical aspects:

  • Operator Dependency: Ultrasound interpretation can vary based on the operator’s skill and technique.
  • Subjectivity: Assessment of features like echogenicity or margins requires clinical judgment and expertise.
  • Clinical Integration: Scores should be interpreted alongside patient history, lab results, and other diagnostic factors.
Enhancing Clinical Practice

The ACR TIRADS calculator is an invaluable asset for radiologists, endocrinologists, and other healthcare providers. By automating complex assessments, it streamlines clinical workflows, reduces errors, and enhances diagnostic precision. Its design allows clinicians to focus more on patient care, supporting evidence-based practices and efficient management.

Improving Patient Communication

In addition to its clinical utility, the structured reports generated by the calculator facilitate clearer communication with patients. These reports provide straightforward explanations of ultrasound findings and their implications, fostering trust and empowering patients to engage in their care plans.

Driving Better Outcomes

Integrating tools like the TIRADS calculator into daily clinical routines supports more accurate, consistent assessments of thyroid nodules. By enhancing workflow efficiency and guiding evidence-based decision-making, it contributes to improved outcomes for both patients and healthcare providers.

In summary, the ACR TI-RADS calculator exemplifies the synergy of clinical expertise and technology. Whether utilized in busy clinical settings, academic training, or research, this tool enables precise and standardized thyroid nodule evaluations.
