In this work, we implemented a 3D flow-dephasing prepared FSE sequence by adding a flow dephasing preparation pulse prior to 3D-FSE acquisition. This enables better blood signal suppression for isotropic high spatial resolution nerve imaging at 3.0T. In-vivo lumbosacral plexus results are shown to evaluate the proposed scheme. We show that flow-dephasing prepared image present significantly better blood vessel signal suppression with high spatial resolution.
