Motivation: Ultra-high field MRI of the brain suffers from an increased B1+ inhomogeneity as well as involuntary motion artifacts when very high spatial resolution is targeted.
Goal(s): Integration of a FatNav technique into pTx Universal Pulse sequences would be beneficial to reach the best image quality at very high resolution.
Approach: An MP(2)RAGE sequence using GRAPE pTx universal pulses was modified to integrate a FatNav module. High-resolution protocols were acquired in vivo on the brain.
Results: Very high-quality images were obtained throughout the brain and cerebellum thanks to FatNav motion correction and pTx Universal Pulses.
Impact: The ultra-high field community targetting high-resolution protocols on the whole brain would benefit from a FatNav-enabled PASTEUR package to bring robust protocols against B1+ inhomogeneities and involuntary motion of the head.
