Microsoft's MAI Health team published research in Science testing its AI diagnostic system, MAI-DxO, which works through complex diagnoses step by step.

On common emergency department presentations from the MIMIC-IV-ED dataset, the company says MAI-DxO was 1.7 times as accurate as physicians. On complex case studies from The New England Journal of Medicine, it was more than twice as accurate as doctors using textbooks and the internet, and nearly four times as accurate as doctors without those resources.

Microsoft says the system got to the right diagnosis at half to a third of the cost, ordering fewer tests and procedures.
