While both conventional and advanced MRI techniques offer important insights into MS pathophysiology, important aspects of this inflammatory disorder are undetectable with existing MRI technology. In Multiple Sclerosis (MS), there is growing interest in PET as an imaging modality that can increase the investigator's understanding of the disease processes and may add to an understanding of MS phenotype, particularly when combined with advanced MRI techniques such as myelin water imaging.
