If a doctor decides to use one in a diagnosis how is anyone else to say they are wrong ? Are those same people saying not to use an MRI going to be liable if the patient dies ? Most doctors I have met want what is best for their patient, often not able to deliver it because of an insurance company or other bureaucrat. When I get sick I want my doctor to do what is best, not an accountant 1000 miles away and definitely not a politician.
Let me bring the discussion back to what my first response was directed at regarding MRI's.
We have 2 situations: 1) The US where anyone can go to their Doctor and get an MRI in an hour(not sure if that's accurate, but for arguments sake let's assume it's true); 2) Canada where someone goes to their Doctor and (usually) has to wait Weeks to get an MRI.
How Sick/Ill are these people?
a) If they are not and just want an MRI, getting one in an hour is completely unrelated to HealthCare and just curiosity. So the US Patient gets some pics of their innards within an hour(ignoring Development/Printing times), the Canadian Patient waits Weeks, perhaps Months, or likely the Doctor refuses o order one. Whatever, nothing is really gained HealthCare wise from this scenario.
b) Patient is somewhat Ill, MRI could be useful. US Patient gets an MRI in an hour, Canadian Patient(assuming the Doctor deems the test useful)gets put on a Waiting List, Its' position on that List depends on the perceived seriousness of the Condition.
c) Patient is very Ill with a Life Threatening Condition, MRI Required. US Patient gets MRI within an hour, Canadian Patient gets moved to the front of the Line and gets MRI ASAP(could be an hour depending on Location, time of Day, equipment in use, whatever).
Keep in mind that for b and c there are usually other Tests that can be performed first to narrow down causes and could possibly eliminate the need for an MRI if they are performed first. Also keep in mind that the Health Outcomes of the 2 Systems are not proportional or even somewhat related to how convenient the access to MRIs is between the 2 systems.
IOWs, access to MRIs between Canada and the US in regards to Quality of Care is a completely Moot point and just a Monkey Wrench thrown into the thread by an experienced Monkey Wrench Tosser(Patranus).
