While underexplored to date, motion susceptibility may critically undermine clinical translation of 3D intracranial MR vessel wall imaging (VWI). Motion artifacts observed in intracranial VWI are either caused by head bulk motion or internally localized movement. By combing volumetric navigators (vNav) and self-gating (SG) strategies, we propose a novel motion compensation approach that can simultaneously address these two motion issues. Our preliminary studies demonstrated the potential of using this technique to improve robustness of 3D intracranial MR VWI.
