We investigated the clinical feasibility of compressed sensing (CS) in the intracranial vessel wall magnetic resonance imaging (VW-MRI) by applying CS to 3D post-contrast T1-weighted images (T1C). CS enabled larger scan coverage with nearly same scan time, while achieving comparable image quality, normal wall and lesion wall delineation. Furthermore, most T1C with CS provided acceptable quality with regard to overall image quality (84.7%), normal wall delineation (83.3%), and lesion wall delineation (97.8%), which was similar to T1C without CS. Therefore, CS is clinically feasible when applied to the post-contrast intracranial VW-MRI.
