Now by all accounts MRI are way way better than X-rays and they save lives. The problem is that most of the time when Dr. orders an MRI scan, he already has a pretty good idea of what is wrong from the X-Ray.[/quote]
I can’t think of any situation where an MRI is made redundant by an Xray. An Xray won’t show anything at all if you have tumor in your brain, an acute stroke, a slipped disk, or a torn ligament - to name four very common uses for MRI.
Now, it’s true that a good diagnostician might not even need any studies at all to decide that you have a tumor somewhere in the brain, some sort of stroke, or a slipped disk somewhere. So if the doctor also decides that the tumor is going to kill you regardless or back surgery is pointless, then you could just skip imaging altogether. But if someone is planning an active intervention, they need to know where to operate. And MRI (or CT) is pretty much an absolute requirement.
As to whether you should operate on a grade IV brain tumor or a tiny slipped disk… well, that’s a different question entirely. In America, the answer is generally yes.
[quote]the total capitals cost of MRIs in the US is over $150 billion or about $500/person
The other 10,000 machine with a cost of $100 billion is spread over about 2 billion people (EU, Japan, and the upper middle class in the rest of the world) or about $50/person[/quote]
I think your denominator is off.
The US has 35.5 MRI machines per million people. Japan actually has more, 46.9 per million. Western Europe averages around 10-20.
In short, other Western countries do spend less, but not by a factor of ten. And I don’t think healthcare systems in the developing world are good points of comparison.
Eh, you’d be surprised. Hospitals will order more MRI machines when demand exists (i.e. waiting times grow too long). Whereas doctors write a prescription for an MRI, and often don’t really care where the patient gets it (much to the dismay of the hospital).
It’s true that doctors want MRI capability for patients in the hospital, but that’s a smaller and smaller share of total exams done, because Medicare pays less and less for inpatient exams. Hence, inpatient machines are often the last to get upgraded. The growth, profits, and competition are in the outpatient centers.
