Hello, Mrs., and Welcome to the absolutely Best Source, from the most-knowledgeable, experienced and finest persons , for the pertinent information and answers which you and your husband seek.

[Hello, again, to all here, Friends & Contacts, et al. I've been away from participating in this particular Forum on NT for awhile now. I'll post on that later in another thread.]

I have been researching for a proper MRI [see Mark's postings for important info on MRI and tesla] for a friend in need of an excellent followup MRI of her brain.

If you and your husband are located anywhere within reasonable travel distance to London, Ontario, you may want to look into possibilities for appropriately brain-knowledgeable care specialists at the University of Western Ontario. [ See quote below.]

I realize that in Canada's national healthcare system you may have to request such a referral from your present physician, general practitioner, family care doctor --- and that may require some sincere persistence to obtain. Go for it, Mrs.

If I were in your place, I would *insist* upon the referral and an MRI of no less than 3tesla, knowing what I know now, --- with all due thanks and appreciation to this Forum and its faithful contributing members --- versus what I knew then, i.e. my own onset of injury in 2008.

I'm learning that such 'imaging documentation' may be crucial for even further-down-the-road as we age and possibly have to contend with age-related aspects/complications.

Dementia, Alzheimer's and Parkinsonian Syndrome can be in fact *head injury related* in etiology and/or early onset. This is hugely ignored in our American healthcare, unless one happens to be a professional sports celebrity --- boxing, football, etc.
Alas, I digress here.

So, Mrs., know that we're here for you and Mr. too.
Check out the info quoted below. I hope that it may be of some help to you. - Sincerely, Theta Z.

"The Robarts Research Institute at the University of Western Ontario, in London, Ontario is one of the household names in the global brain imaging community."

"MRI field strength is measured in Tesla units.
Clinical MRI scanners [typically] operate at 1.5-tesla.
In 1996, Robarts became the first and only facility in Canada (and one of very few in the world) to house a 4-tesla MRI scanner."
