MRI strength

I went for another MRI on Friday and asked the tech what strength the machine was.  I've had 2 previous MRIs on the same machine and was curious.  She informed me it is a 1.5 Tesla; and further stated that 3T's are only ever used for research purposes.  

I wasn't surprised that the local machine is a 1.5T.  I live in a small city several hours away from a major centre.  We only got the MRI at our local hospital a couple of years ago.  It's not surprising that it's not the most cutting edge of technologies.  

But I found it interesting that the tech was so uninformed.  As we all in this forum know, 3T's are used as a diagnostic tool, not only in research.  I didn't debate this point with her, but it occurred to me that as a person with MS (or even in limbo), that in many ways one becomes more knowledgeable that those who are there to test, diagnose and treat us.  

I would have trusted she knew what she was talking about and simply taken her response as fact, had I not learned otherwise from this forum.  Actually I probably wouldn't have even known to ask the question in the first place.

Hi everyone,

I'm glad we can use the forum to share ideas and learn what important questions we need to be asking, but I also think that we need to respect the opinions and training of the professionals trying to help us.  (OK, maybe sometimes they don't all deserve it!)

I thought that a 3T machine can demonstrate anatomy with a higher signal-to-noise ratio.  So it may be a nicer picture, but it is not more sensitve.  Senstivity and resolution are not the same thing.  Besides, this is only one of several factors in an MRI exam - others include the technologist, reader, machine and patient.

Personally, I'd rather have a more senstive doctor than a more senstive machine, but I know we are all in different situations.  Just my 2 cents.

When I asked my 1st neuro for a 3T , He snapped his head up and said,  " You're a tough one . "    I just shyly smiled ,    I learned both things from this forum ( and sooo much more )

When my results were in and he was going over it with me , he said something interesting and odd   .   That my lesions would probably not have shown up on a 1.5T which the McDonald Criteria is based on .   He eventually threw out all of my lesions , so I threw him out ( some more great advise ).

Its amazing how much information we have gotten on this site . I think we would be in deep sh** if it were not for this place ..  THANK YOU EVERYONE  

  Love    :)     Jo

I second all that you have said.  I have learned so much from this Forum in the past year.  Lucky for my doctor I was not as  knowledgeable about MS as I am now.  I would have had a lot more questions back in 2005 and would have probably really made him flounder.  

I have got to say in his defense that he was pretty swift with my dx though. I still don't know what strength the machine was, though.
