Stanford researchers unveil Merlin, a foundation AI model that outshines specialist models in analyzing 3D CT scans for diagnostics and disease prediction.
Key Details
- 1Merlin is a vision-language foundation model for 3D abdominal CT analysis, trained on over 15,000 scans, radiology reports, and nearly 1 million diagnosis codes.
- 2The model was evaluated on over 50,000 unseen abdominal CT scans from four hospitals.
- 3On diagnostic coding, Merlin achieved over 81% accuracy across 692 codes and 90% for a subset of 102 codes, outperforming specialist models.
- 4Merlin accurately predicted 5-year risk of chronic diseases from scans 75% of the time, compared to 68% for an existing model.
- 5The model processed both standard and out-of-domain CT scans (chest), matching or surpassing existing tools even outside its training scope.
- 6Researchers hope the model will accelerate clinical workflows and support new biomarker discovery in radiology.
Why It Matters
Merlin's broad capabilities and superior performance signal a shift towards foundation models in medical imaging AI, offering improved diagnostic accuracy, workflow efficiency, and potential for new clinical insights in radiology practice.
