Stanford researchers introduce Merlin, a 3D vision-language AI model for interpreting abdominal CT scans, demonstrating strong performance across multiple radiology tasks.
Key Details
- 1Merlin is a 3D vision-language model designed for abdominal CT interpretation.
- 2Evaluated on over 44,000 CT scans from multiple sites covering various anatomies.
- 3Trained on over 6 million CT images, ~2 million diagnosis codes, and 6 million radiology report tokens.
- 4Tested on 752 individual tasks: zero-shot classification, disease risk prediction, cross-modal retrieval, report generation, and 3D organ segmentation.
- 5Achieved 0.741 F1 score for zero-shot classification and AUROC of 0.757 for chronic disease risk prediction over five years.
- 6Model and code are publicly available on GitHub, HuggingFace, and PyPI.
Why It Matters
This foundation model provides a significant step forward in automating CT scan interpretation, potentially alleviating radiologist shortages and expediting workflow. Its public release allows the broader research community to build and benchmark further advances.
