Google Launches a New Medical App--Outside the US

Now, Google is preparing to launch an app that uses image recognition algorithms to provide more expert and personalized help. A brief demo at the company's developer conference last month showed the service suggesting several possible skin conditions based on uploaded photos. Machines have matched or outperformed expert dermatologists in studies in which algorithms and doctors scrutinize images from past patients. But there's little evidence from clinical trials deploying such technology, and no AI image analysis tools are approved for dermatologists to use in the US, says Roxana Daneshjou, a Stanford dermatologist and researcher in machine learning and health. "Many don't pan out in the real world setting," she says.
