A preliminary imaging study for MPRAGE with Wave-CAIPI has been introduced at the clinical MR scanner. MPRAGE with Wave-CAIPI 3×3 shows relatively better contrast despite its short scan time. Less imaging noise and segmentation error was found in MPRAGE with Wave-CAIPI 3×3. MPRAGE with GRAPPA 3×3 showed prominent imaging noise and segmentation errors, however, MPRAGE with CAIPI 3×3 showed few segmentation errors and almost equivalent to Wave-CAIPI 3×3.
