Assessing the accuracy of ChatGPT-5.6 in American College of Radiology Thyroid Imaging Reporting and Data System feature scoring and classification from synthetic free-text thyroid ultrasound reports

ObjectivesThe American College of Radiology Thyroid Imaging Reporting and Data System (ACR TI-RADS) provides a standardized framework for thyroid nodule risk stratification based on predefined ultrasound features. This study aimed to evaluate the accuracy and robustness of ChatGPT-5.6 Sol in extracting and scoring ACR TI-RADS features and classifying thyroid nodules from synthetic free-text ultrasound reports.MethodsA primary dataset of 100 synthetic thyroid ultrasound reports was constructed, with each report d…

Current reading — gain

On synthetic free-text thyroid ultrasound reports, the model identified and scored all five TI-RADS feature categories and assigned the final risk category with no errors against reference annotations.

What this doesn’t fix

The reports were synthetic, and the authors state that further validation in larger and more diverse settings is needed to establish generalizability.

How to verify without trusting this page

Fetch the canonical text of any version from /api/record/TRV-2026-1605 and hash it yourself — for example shasum -a 256 on the saved canonical field. The result must equal content_hash, and each version’s text ends with prev:followed by the prior version’s hash (version 1 chains to 64 zeros). If a single character of any version had been altered since certification, the chain would not reproduce.
