Would you get a whole-body MRI scan to check for cancer and other problems even if you don’t feel any symptoms? Some have done just that and saved their lives.

Others simply find out that they're relatively healthy.

I seem to fall somewhere in the middle.

I recently did a 60-minute full-body MRI scan. I learned I'm mostly healthy, but there are some potential problems. The CEO and co-founder of the company that ran the MRI says that adopting these kinds of scans would be part of a switch from sick care to health care, and it could save both millions of lives as well as billions of dollars.

We chat about the technology, how it works, what it can do, and what it can't do. We also talk about why doctors are in general skeptical ... and why my doctor specifically didn't take the results super-seriously.
