# Is a whole-body MRI scan (Prenuvo, Neko Health) worth it for a healthy person?

For an average-risk, symptom-free adult, the evidence does not support a whole-body MRI. No randomized trial has ever tested whether these scans lower death from cancer or from any cause. Pooled cancer detection sits at about 1.57%, while roughly 95% of scans flag at least one abnormality, and about 91% of those mean nothing. The clear exception is people with a high-risk hereditary syndrome like Li-Fraumeni.

No trial has ever tested whether these scans save lives. If you are an average-risk adult, what you really buy is a near-certain pile of incidental findings.
