Study Design
Five participants per age group (ages 25-35, 45-55 and 65-75) or 6 participants per age group (ages 8-9 and 14-15) were studied in Phase 1a to evaluate their ability to tolerate the MR sessions. Data for the 4-6 year old group was not collected in Phase 1a because the pediatric head coil wasn’t ready yet.
