MHTop comment: @mcahogarth “Yep, most of these things are benign or resolve themselves without intervention. That's why I say the barrier is cheap monitoring. Getting multiple MRIs to keep an eye on an anomaly is unreasonable. You have to treat everything you see as a potential problem, because no one is going to schedule and pay for a sequence of imaging. One full body scan a year? Useless. One a week? Different story. That much data might change our understanding of the body's fluctuations, also, which means those false positives might reduce, and we'll know 'this is typical of most humans, this is when it becomes actionable.' But we just don't have the data to have those insights. Yet.”
