A new AI anomaly detection model accurately locates tumors on breast MRI and surpasses established benchmarks in diverse patient populations.
Key Details
- 1The AI model was trained on nearly 10,000 contrast-enhanced breast MRI exams from the University of Washington (2005-2022).
- 2Compared to traditional binary models, this anomaly detection approach better identifies rare malignancies using explainable, pixel-level heatmaps.
- 3The study included validation on both internal (171 women) and external (221 cases) datasets, including low-prevalence screening settings.
- 4Model outperformed standard benchmarks in detecting and localizing biopsy-proven cancer in multiple test groups.
- 5If rolled out clinically, the model could triage normal scans to improve radiologist efficiency, though further prospective validation is needed.
