Microsoft's AI diagnoses complex cases better than doctors

Microsoft's new AI system, MAI-DxO, achieved an 85% diagnostic accuracy rate on complex medical cases, outperforming human physicians by a significant margin. This suggests a major advancement in AI's ability to assist in medical diagnosis. The system, tested on challenging cases from the New England Journal of Medicine, uses a "virtual panel" approach, combining multiple AI models to analyze patient information and suggest diagnoses. This approach allows for a more comprehensive and accurate assessment than individual models or human doctors. While promising, Microsoft emphasizes that MAI-DxO is designed to assist doctors, not replace them. The system also incorporates cost-benefit analysis, potentially improving efficiency in healthcare.
