An assessment of ChatGPT in error detection for thyroid ultrasound reports: A comparative study with ultrasound physicians.

Background: This study evaluates the performance of GPT-4o in detecting errors in ACR TIRADS ultrasound reports and its potential to reduce report generation time.

Methods: A retrospective analysis of 200 thyroid ultrasound reports from the Second Affiliated Hospital of Fujian Medical University was conducted, with reports categorized as correct or containing up to three errors. GPT-4o's performance was compared with ultrasound physicians of varying experience levels in error detection and processing time.

Results: GPT-4o detected 90.0% (180/200) of errors, slightly less than the best-performing senior ultrasound physician's 93.0% (186/200) with no significant difference (0.281). GPT-4o's error detection rate was comparable to that of ultrasound physicians overall (0.098 to 0.866). It outperformed Resident 2 in diagnostic errors (87% vs. 69%). Reader agreement was low (Cohen's kappa = 0 to 0.31). GPT-4o reviewed reports significantly faster than all ultrasound physicians (0.79 vs. 1.8 to 3.1 h, < 0.001), making it a reliable and efficient tool for error detection in medical imaging.

Conclusions: GPT-4o is comparable to experienced ultrasound physicians in error detection and significantly improves report processing efficiency, offering a valuable tool for enhancing diagnostic accuracy and aiding junior residents.
