Selected pediatric patients (3-9Y) scheduled for a clinical brain MRI under general anesthesia are enrolled in this ongoing study to be scanned awake, while watching a movie for entertainment, using a new motion-robust brain MRI protocol. The protocol consists solely of custom-made, inherently motion-robust, sequences, with all necessary MR contrasts for clinical use. All but one sequence uses real-time correction of head motion with an external tracking device. All eight unsedated pediatric patients scanned so far resulted in diagnostic images, despite some patients moving their heads in excess of 30 degrees (peak-peak) during the exam.
