I have no doubt that Dr's do order unecessary tests for alot of reasons, one of which is defensive medicine.
Dr. Robert Boyd, an orthopedic surgeon at Massachusetts General Hospital in Boston also mentioned
“insecurity, inexperience and the potential for economic gain”, but that's OK, most seem to reach for the defensive (i.e. malpractice protection) angle and ignore the others.

But, I would guess that one of the problem with your point, is that Dr.s in NHS systems are still sending their patients to have MRIs. It's just that those wait times for the MRI are much-much higher there then here. High enough that it could b ecosting lives.
Not trying to defend the NHS in England or the system in Canada, as there are no proposals in the U.S. even remotely approaching anything similar to those programs, but what caught my attention was trying to use the number of MRI machines as a measure of a 'good' vs. 'bad' health care system.
The overuse, abuse and unnecessary use of some technology does cause, as has been proven in the U.S., inflate the cost of healthcare. So having 'x' number of MRI machines per 'x' number of people doesn't mean much, except we spend a bunch more $$$ on health care.
What your article doesn't say is, how many of those that have to wait longer are considered 'low risk' by their physicians and how many of those that actually do need the tests right away get them right away. Like your post, there were a lot of "could', "may', and "potentials" in the article. No hard facts of actual causation.
A colonoscopy is generally recommended at age 50 and if the results are normal, another in about ten years. Depending on what is found, a followup could be in three to five years. So a six week wait, after seeing a doctor would not be life threatening.
A sigmoidoscopy is a less invasive, usually a precursor to a colonoscopy. Recommended every five years. Six weeks isn't a problem.
An echocardiogram is nothing more than a sonogram (like a pregnant mother gets) of the heart and blood flow. It's generally used by a cardiologist in diagnostic and followups with their patients. No rush. Again the physician will prioritize the patients and those with urgent needs will be moved to the front of the line.
