Dana Milbank, The Washington Post ; A full-body MRI can reveal hidden killers. Do we want to know?
"The new technology that powers these full-body MRIs — something called diffusion-weighted imaging (don’t ask me to explain) combined with the pattern recognition of artificial intelligence — has the potential to save our lives by revealing budding cancers, silent aneurysms and other hidden would-be killers before they become deadly.
But the scans cost $2,500 a pop and insurance won’t pay. Worse, for every cancer these MRIs find, they produce a slightly greater number of false positives that require a biopsy, with the potential for infection and bleeding and emotional distress. Even when the scans don’t produce a false positive, they almost always come up with some vague and disconcerting abnormality.
Like many emerging technologies, this one can improve our lives, make us miserable, or both. Nobody yet knows which it will be, because we’re the first humans to have the option of examining our innards with such clarity. Will we feel better after viewing our insides? Or will we become anxious about things we hadn’t even thought to worry about?"
