ChatGPT-4's Accuracy in Estimating Thyroid Nodule Features and Cancer Risk From Ultrasound Images

Endocr PractPublished Diagnostic accuracy study

Authors' conclusion

While GPT-4 and GPT-4o models show potential for improving the efficiency of thyroid nodule triage, their performance remains suboptimal, particularly in higher-risk categories. Further refinement and validation of these models are necessary before clinical implementation.

Study context

Population
Thyroid nodule US images from 3 open-access databases, assessed with ACR Thyroid Imaging Reporting and Data System (TI-RADS)
Participants
202 thyroid US images
Comparison
GPT-4 and GPT-4o vs expert radiologists' reference standard for TI-RADS features and categories
Outcome
Accuracy in identifying TI-RADS features and categories vs the reference standard
