Report from ISMRM: Ultrahigh-field MRI improves characterization of multiple sclerosis

May 9, 2008 Report from ISMRM: Ultrahigh-field MRI improves characterization of multiple sclerosis James Brice -------------------------------------------------------------------------------- Diagnostic power and field strength go hand in hand when it comes to evaluating multiple sclerosis. It is no secret among board-certified radiologists that 1.5T MRI misses many MS-related white-matter lesions found during postmortem histology. It is unable to characterize much gray matter pathology at all. This problem stems from limitations of spatial resolution and contrast that are solved by raising the field strength to 4.7T, according to Dr. Amir Eissa of the University of Alberta.
