Pediatric magnetic resonance imaging (MRI) needs extra care since patients cannot remain still for long in the MRI bore. Therefore, scans should be performed as quickly as possible. Our study investigated the role of fast T1 3D Magnetization Prepared Rapid Acquisition Gradient Echo (MPRAGE) scans using wave-controlled aliasing with parallel imaging (wave-CAIPI) in pediatric patients. We presented that scan times were shortened significantly, and images had fewer motion artifacts compared with conventional MPRAGE images. We further evaluated contrast-to-noise ratios (CNRs) in five cerebellar areas and saw no significant differences between the conventional and wave-CAIPI MPRAGE images.
