Intra-nasal Dexmedetomidine for Children Undergoing MRI Imaging

This study aims to assess the use of intranasal dexmedetomidine (IN-dex) as a sole agent in aiding the successful completion of a MRI scans in children. Dexmedetomidine, a routinely used anesthetic agent in our institution, has many benefits including sedation with neuro-protective and respiratory sparing features. We will test its effectiveness in completing MRI scans in children that would otherwise be given a full general anesthetic.
