Okay that’s a very surprising number of MRIs…

I’m in my early 40s and have had 1. Everyone I know well has had 1 or (more typically) none, including my parents and in-laws, so I figured ~2 lifetime MRIs would be in the right ballpark

Well apparently there are ~40m MRIs per year in the US, implying around 9-10 lifetime MRIs, which seems... pretty high? It's also wild that, at 85-90m CTs per year, apparently the average person is getting more than 20 lifetime CT scans.
And the distribution is likely heavily skewed in one direction. For example, Medicare recommends and covers annual chest CT for smokers and ex-smokers.
Oh for sure it’s skewed, and it doesn’t surprise me that there are people that will get 20+ CTs. Wild that that’s the average though - the skew must be massive.
