Whole-brain intracranial vessel wall imaging (VWI) requires long scan time for high resolution and large coverage. In this study, we applied a novel three-dimensional parallel imaging technique, Wave-CAIPI, to accelerate whole-brain intracranial VWI. The highly accelerated (11×) VWI takes 3.5 minutes, at an isotropic resolution of 0.6 mm. Compared to conventional two-dimensional parallel imaging technique (2D CAIPI), Wave-CAIPI is able to achieve higher SNR and better imaging quality on vessel wall depictions.
