AI tool can assess a person’s health by analyzing a photograph

Scientists have developed an A.I. tool that they say can help assess a patient’s health — and potentially guide their medical care.

In a new study, published [May 8] in The Lancet Digital Health, researchers trained artificial intelligence to estimate the biological ages of adults with cancer by analyzing photos of their faces. Study participants with younger estimates tended to fare better after treatment than those deemed older by A.I., researchers at Mass General Brigham found.

The findings suggest that people’s biological age estimates are closely linked to their physical health, which could reflect their ability to survive certain treatments, the authors of the study said. And in the future, facial age analysis may become more useful than age alone in helping doctors make tough calls about their patients’ treatment, they added.                           

Face-based aging tools have “extraordinary potential” to help doctors quickly and inexpensively estimate how healthy their patients are, compared with existing tests.
