The purpose of this investigation was to measure the brain blood flow differences between 2 MRI sedation techniques commonly used in pediatric radiology: propofol-based sedation technique and the combination of ketamine and propofol. We performed retrospectively gated 2D cine phase-contrast MRI in 58 pediatric patients and measured the arterial and jugular blood flows and compared these values between the 2 groups.
