Open-Source AI Matches Commercial Tools for Radiology Scan Reporting
July 23, 2025
Open-source AI tools can perform as well as costly commercial systems in reading and structuring radiology reports without compromising patient privacy.
Key Details
- University of Colorado study evaluated free, open-source AI models against commercial tools (e.g., GPT-4) for analyzing thyroid nodule ultrasound reports.
- Researchers created 3,000 synthetic radiology reports for model training to avoid using patient data.
- Six open-source models were tested; Yi-34B matched GPT-4 accuracy, and smaller models sometimes outperformed GPT-3.5.
- Testing was performed on 50 real public patient reports using the ACR TI-RADS scoring system.
- Open-source models can run locally within hospital systems, avoiding privacy risks and high infrastructure costs.
Why It Matters
This research demonstrates that hospitals can safely and affordably deploy effective AI to aid radiology reporting, reducing privacy risks by eliminating the need to export sensitive data. The successful use of synthetic data and locally-run models points toward practical, scalable AI solutions for clinical workflows.
