The story in three lines
- Key finding
- On difficult published case records, MAI-DxO reached the correct diagnosis far more often than generalist doctors working under test conditions.
- Significance
- Clinical: shows sequential, step-by-step AI diagnosis can be tested rigorously, but only in simulation so far.
- Takeaway
- Promising for complex cases; prospective trials with real patients are still needed.
