In this work, a GRAPPA-based reconstruction for wave-CAIPI acquisitions is presented. 16-fold accelerated full brain MPRAGE images with 1 mm isotropic resolution and high image quality are measured in 45 seconds and a clear improvement compared to Cartesian CAIPIRINHA sampling can be observed. It is demonstrated that optimization of the gradient waveforms further improves image quality.
