Quix, thank you for putting your thoughts in here.
I personally would love to see my brain on a 7T as a limbolander, perhaps it would give me the answers I lack, do to my lesions simply looking like patches. I don't want to be a lesion counter, but then I have to work with my neuro's who at times are.
I do hope that some-day this will help others like me who are looking for answers.
Good discussion

I have to pose a little other information here. The magnetic field disturbs the individual molecules and not the cells themselves. The question is whether the field is powerful enough to actually change or break the molecular bonds. That is the real issue. Also, though they don't really have the info, the difference between living close to a high magnetic field and having a 7T imaging is the time spent exposed to the field.
The comparison is 50 minutes in a very high field versus 24/7 for years exposed to a lower one. They are being quite cautious as they approach this new strength.
I agree with Laura. I don't care if this 7T remains a research tool. If it can provide more information about how this disease does its thing, then it is a very good tool to have.
But, I'm with Elaine as far as something like this becoming the "Gold Standard" as far as diagnosis. Though I want high-resolution imaging, I do NOT want to see a test become the only tool used to diagnose a disease like MS.

Wow, how exciting and interesting! All of mine have been on a 1T machine. The lesions show up, but they are truely horrible pictures. I can't wait to see the comparison.
Elaine,
You raise very valid concerns about the use of this type of force. From what I know, even though the magnetic field of an MRI can and has been built stronger, 7T will probably max out what the living human can be subjected to.
I don't have my paperwork here at work, but the research study specifically sets a limit of the number of MRI's that can a person can have on this machine over a lifetime. The physicist in charge of this machine told me she has been in it over 30 times for a full brain scan, with no ill effects.
As for the personal risk, I did this scan knowing full well that they don't know yet what the long term effects could be. I view this no differently than participating in a clinical trial or helping with other medical unknowns. Lots of chances were taken by the people who participated in the drug trials before we had wide access to the DMD's available now. I see this as a very well controlled, calculated risk, much safer than those trials or the current drugs being tested.
Hopefully the opportunity to study the grey and white matter of the brains of MS patients will lead investigators to new ideas and discoveries of how this disease develops in all of us.
My best,
Laura
wow... that's a strong mri... I'm glad you got to use it and see the difference.
I can't seem to get a T3 mri here..they do have a couple...but the specialist isn't sending me for one?? I just don't understand...if they are questioning my lesions you would think they would want a better look at them??
take care

HOLY C R A P!!!!!!!!!
Niiice! Oh, Laura, I'm happy for you. This is some opportunity.
They looking for anyone else?
When will you hear about what they saw?

Hi ,
Read your post regarding the 7T. Raised a curiousity question for me, do you and your physicists friends feel the same regarding the lower strength magnets or just the 7T or I guess for that matter, the 3T? Don't all the MRI machines disrupt the cells in the same manner, just to different degrees?

Part II - the test
The doctor who ran the machine and is doing the study on the 7T machine is looking at the imaging quality of both the white matter and the grey brain matter. When my test was concluded, she sat with me and my husband at their computer and showed us a sampling of my brain images.
Less than 2 hours earlier my husband and I had seen my brain MRI from December on my neuro's computer and discussed my lesions with him, so I had a very fresh memory of what I should see.
A "blob" of a lesion - actually looks like a paint splatter on the 1.5 picture - transformed into a different shape on the 7T. It is actually "S" shaped, and is open on both ends. Wow! My blood vessels and arteries were so clear in the details.
Even more amazing, she was able to show me the grey matter and point out what she believes may be more lesions. This doctor is a physicist responsible for the MRI machine and not a radiologist or neurologist. The true interpretation of the films will be done in the next few days.
Of course I asked for a copy of the MRI for my records - but they are using a totally different program to view these films and it isn't like the 1.5T and 3T programs. She is going to burn some of the more picturesqueviews in jpeg format for me and send them on. When I get these images I will post comparisons for you to see. My neuro will have full access to these films and on my next appt. you know I will be asking to see them.
Among other things, they are hopeful that this increased detail will shed some clues on the structure of what's causing the myelin destruction. The 7T machine should be providing more answers for MS researchers.
Overwhelmed,
Lulu
I'll throw my hat into the ring as well for the guinea pig thing but, only if it invoves the 7T!
Did you give them my name and tell them I could be a guinea pig too? ;D
I already saw a bunch of the images - I wrote about them in the next post. And yes, I love being a guinea pig! It was amazing. I keep using that word, but can't think of a better adjective ............
Congrats on being a guinea pig, just kidding. But how neat was that, that you got an opportunity to experience cutting edge technology! When will they tell you how the 7T compared to your 1.5 T MRI results? Keep us updated!
