Pediatric patients are preferred to be scanned with protocols which are resistant to motion artifact or which complete in a short scan time. We investigated the extent of motion artifact suppression in pediatric patients using modified multi-echo Magnetization Prepared Rapid Acquisition Gradient Echo (MEMPRAGE) with prospective motion correction using 3D EPI volumetric navigators (vNav Moco) by comparing with wave-controlled aliasing in parallel imaging (wave-CAIPI) MPRAGE. Visual assessment revealed vNav Moco MEMPRAGE significantly suppressed head motion artifacts compared with wave-CAIPI MPRAGE and conventional MRPAGE.
