Before I got my Prenuvo MRI everything online said “don’t do this, man. You’ll find all sorts of things that will worry you that you wouldn’t be worried about if you didn’t do it”. That makes no sense to me. Totally irrational. So I did the scan and saw a bunch of things which had no clinical significance - including the amusing thing that I’m missing the transverse processes on a couple of vertebrae (easily explainable from a motorcycle accident that put me in the ICU). So I moved on, scan done, and with the docs in my family reviewing.
But a friend of mine went through a different diagnostic procedure and found things of equal clinical significance and went through a large number of interventions which he didn’t really need it now turns out. And then I understood why people provide this warning.
So the first question to ask yourself is which kind of person you are.
