Microsoft claims its AI tools can diagnose complex medical cases better than doctors

In addition, the firm’s SD Bench platform has introduced new benchmarks that 'transforms 304 NEJM cases into interactive diagnostic simulations'

Tech giant Microsoft reported crucial advancements in its pursuit of “medical superintelligence”, with two key achievements in the healthcare artificial intelligence space.

The US-based firm’s AI research team said that its Microsoft AI Diagnostic Orchestrator (MAI-DxO) has successfully diagnosed 85 percent of the New England Journal of Medicine (NEJM) case proceedings, which is four times more than a group of experience doctors.

The company claimed that its diagnosis is “more cost-effective than physicians”.

In addition, the firm’s SD Bench platform has introduced new benchmarks that “transforms 304 NEJM cases into interactive diagnostic simulations”.

“Together, these advances offer a blueprint for how AI can help deliver precision and efficiency in healthcare, and we're looking forward to working with healthcare partners and the entire ecosystem on these advances making a difference,” Microsoft chief executive officer Satya Nadella said in a post on X.

Microsoft claimed that these advancements can provide solutions to medicine’s most complex issues. “(Microsoft’s) research demonstrate how AI can sequentially investigate and solve medicine’s most complex diagnostic challenges—cases that expert physicians struggle to answer”, the firm said in a statement.

The healthcare costs are rising rapidly globally and people are turning towards tech to provide cheaper resolutions. Microsoft, in its statement, said it wants to “do more to help” and believe gen AI can be “transformational” in that regard.

“That’s why, at the end of 2024, we launched a dedicated consumer health effort at Microsoft AI, led by clinicians, designers, engineers, and AI scientists.”
