Someone told me that there are more CAT scanners in Southern California than in all of Canada
Could be - there are more people in California than in Canada.
I was told Southern California- 12 million or so, you can drive across it in a few hours, as opposed to Canada at 25-30 million, takes 2 days to drive across.
Even then, CA and CN are close in population, give or take 20%.
I've heard the arguable slur in this country that hospitals buy excessive expensive equipment - and then schedule people for expensive tests that they really do not need - to pay for the equipment. Who knows?
