I have learned in the past on this forum that all MRI machines are not equal. Can someone in the know please school me on what MRIs are better than others? Something like a "good, better, best" list??
Thanks!
Not officially diagnosed due to non-MS-specific spots on MRIs, but the neurologists all agree it's MS.
Frustrated. January 2019: finally saw an MS specialist worth seeing. Maybe we'll get to the bottom of this.

Symptoms began in JAN02
- Dx with RRMS in OCT03, following 21 months of limbo, ruling out lots of other dx, and some "probable stroke" and "probable CNS" dx for awhile.
- In 2008, I was back in limbo briefly, then re-dx w/ MS: JUL08. - Betaseron NOV03-AUG08; Copaxone20 SEPT08-APR15; Copaxone40 APR15-present - Began receiving SSDI / LTD NOV08. Not employed. I volunteer in my church and community.
Thank you. So, the 3T machines are still the "gold standard"? That particular thread is almost 6 years old, but I assume nothing has changed. I'll ask the neuro which machine they use.
Thanks again!!

The Cleveland Clinic has a 7T MRI scanner, but according to this article, their use is limited.
This info is from the article Ultra-High-Field MRI:
The rationale for 7T
"The principal clinical advantage of 7T imaging stems from increased spatial resolution, including both in-plane voxel spacing and slice thickness. Initial experience suggests that although few lesions are seen at 7T that are not visible at a lower magnetic field, those seen at a higher field are seen with higher resolution and greater neuropathology detail — sometimes leading to an altered diagnosis not appreciated at lower fields. For example, 7T is superior for visualization of microhemorrhages, and it can reveal an increased extent of traumatic brain injury than is seen at lower fields."
My interpretation is that if there are lesions present, they will be visible at a lower magnetic field. However, the 7T would give more detail of those lesions if they are questionable, and if needed for a diagnosis.
Take Care

Makes total sense; thank you!!

Here's another article I just received in my email from NMSS about mri's and also some possible safety concerns using gadolinium contrast agents with an mri
...and also some possible safety concerns using gadolinium contrast agents with an mri
Oh dear. More to worry about!!!
Thanks - I'll check it out
