简要总结
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.
详细描述
This is an exploratory study. PBR28 PET scan is new, promising and exploratory endpoints in MS clinical trials, making sample size estimation difficult.
A separate pre-screening consent form will be issued for the TSPO rs6971 polymorphism and eGFR blood samples, a separate pre-screening step. Eligible participants, according to their TSPO rs6971 polymorphism will be presented a separate study consent form to continue into the clinical trial.
Study Assessments include 1 PET scan, 1 MRI scan, OCT, EDSS exam, physical exam, cognitive questionnaires, etc.
