> You also express a false dichotomy - single MRI bad, but monthly MRIs for life good? yeah, this is badly expressed on my part. I was trying to get across that a single whole body scan without context (ie it hurts here, or it bleeds there or we suspect x) is difficult to interpret. think of it as a day's unstructured logs. Regular scans allows you to build up a picture of whats changing, and whats normal for you. > A sober reading of annual MRI/Ultrasound type tests without knee-jerk invasive followups when you are 30+ seem like a reasonable risk weighted solution in contrast, doesn't it? I think routine targeted scanning is something that is worthwhile. The UK does a number of them, and they were normally based on evidence of outcome. Prostate/breast/cervical etc etc. I personally think the future of public health is something akin to getting each personal a vitals dashboard. But, I'm not sure regular MRIs will give us that. if the evidence changes though, then it should be reassessed.
