Total Cerebrovascular Blood Flow and Whole Brain Perfusion in Children Sedated Using Propofol With or Without Ketamine at Induction: An Investigation With 2D‐Cine PC and ASL

BACKGROUND Multiple sedation regimes may be used to facilitate pediatric MRI scans. These regimes might affect cerebral blood flow and hemodynamics to varying degrees, particularly in children who may be vulnerable to anesthetic side effects. PURPOSE To compare the effects of propofol monosedation solely (Pm group) vs. a combination of propofol and ketamine (KP group) on brain hemodynamics and perfusion.
