You can only do as many MRIs as you have machines to do them. So you're either not doing them as often as we are or waiting longer or both.
But I"m not sure you follow the marginal issue. Let's say there's only a .00001% an MRI is going to find something (say for instance patient just has a mild headache, not chronic). Do you do the MRI? Well, no, because there's only one chance in a million you find something useful.
Now realize, this means one time in a million you are missing something useful. But since you don't have an infinite supply of MRIs you have to make cost/benefit decisions.
So where do you draw the line? .1%? 1%? 10%? To some extent the answer must be limited by the availability of MRIs.
I'll link this again since you obviously didn't read it last time:

You keep going on about MRI machines as if it is some kind of conclusive proof of superiority. That article there, which is based in fact, says Japan enjoys 2x the actual scans per capita as the U.S. I think that's a more relevant metric, don't you?
Having more machines doesn't matter in the slightest if they're mostly idle?
Not really. Fully utilizing the machines would be inefficient in terms of the practice of medicine. You need open slots to handle emergencies and variations in the (hopefully short) que.
It is like any factory. If it operates at the 99% utilization level any small disruption will cause material to pile up.
Ideally the utilization factor should be such that the average time to process a "unit" is small.
So in fact "wasting" resources can give a better outcome if done intelligently. It is the principle behind the Just In Time (JIT) factory. [I'm surprised no manufacturing engineers have jumped in here. I guess as a contractor I have been very lucky. I have been exposed to many facets of business. My employers educated me. Of course I have been a willing student. On one of my first EE jobs I learned how to troubleshoot a production line. Very short version: look for the places material is piling up and find out why. Fix the problem if it is machinery or method. Load balance - i.e. try to find the best way to deploy the available labor. ]
Any one familiar with the ins and outs of an Ethernet bus could explain it. To get maximum throughput in a multidrop bus you keep loading generally at or below the 10% level. You can go higher (~ 80%) if the bus is strictly point to point.
If you keep the loading high with a priority scheme there are some messages (people) that will never get through. Which is one reason why the internet can't guarantee delivery of a given packet especially at high load times.
If the Japanese are getting 2X the MRIs per machine the Americans do (did I read that right?) the Americans probably have a better system in terms of medicine. And we have that all important surge capability.
A really high quality medical system is not going to rate high in terms of use of resources. Machines will sit idle and doctors will be overpaid (it attracts brains with the requisite manual dexterity to the field). Of course those same symptoms in a different system could be signs of waste.
So are Americans getting their money's worth? About 80% of Americans with health insurance think so. Cut that back to about 60+% for all adult Americans.
So what is to be done? Fixes at the margins only. No grand schemes. Treat it like a business - keep the happy customers. Figure out how to attract new ones.
Looking at raw numbers (life expectancy) is a mug's game. You have to go deeper (the critical one is survival rates for various problems and other things - like % of the population needing treatment that actually get it in a timely fashion).
I'm sure the rest of the wold (because they are poorer) can't afford the waste that makes the American system so efficient in terms of outcomes.
Perhaps a little cowboy capitalism is in order. It might mean better medical treatment.
