Do you think those differences are relevant to the point being made?

Yes it is, because if you know they're different then you're literally moving the goalpost: We were talking about CT scans but the difference in CT scans both sides of the Atlantic has nothing to do with the availability of CT scan machines so you switch to another equipment in the middle of the discussion.

Also, your numbers are cherry-picked: Japan has more MRI machines per capita for instance, and Germany or even Greece aren't far behind the US.

We’re talking the overuse of diagnostic testing using expensive equipment in the U.S. My anecdote happened to involve a CT scan, but the data I had seen on it focused on MRIs: https://www.healthsystemtracker.org/chart/per-capita-u-s-thr...

I used Canada as a data point because it’s common to compare the U.S.’s healthcare system to Canada, because the countries are otherwise pretty similar. Japan and Greece have very different populations.
