Microsoft announced a scientific breakthrough in medical diagnostics on July 1, 2025, unveiling the MAI-DxO artificial intelligence system, which has demonstrated superhuman accuracy in diagnosing the most complex clinical cases. The research findings confirming the systems effectiveness were published in one of the worlds most prestigious and authoritative medical journals, The New England Journal of Medicine (NEJM), lending particular weight to the discovery. According to the published data, the MAI-DxO system achieved a stunning 85% accuracy in diagnosing complex cases, where a group of experienced specialist doctors averaged around 20%. This staggering result was achieved thanks to the AIs ability to simultaneously analyze and correlate vast arrays of diverse patient data: complete medical history, results of hundreds of lab tests, medical imaging data (MRI, CT), and the content of clinical notes, identifying hidden patterns often inaccessible to human analysis. Microsoft is positioning this development not just as another diagnostic tool, but as a significant step towards creating a "medical superintelligence" – systems capable of working in close partnership with doctors and significantly surpassing them in tasks requiring big data analysis. It is anticipated that in the future, such technologies could drastically reduce the number of diagnostic errors, accelerate the correct diagnosis of rare diseases, and provide access to world-class expert knowledge in remote regions. This breakthrough strengthens Microsofts position as one of the technological leaders in the application of AI in healthcare.
