Accurate morphological measurements and classification of carotid plaques require imaging with high spatial resolution, and may benefit from the increased signal intrinsically available on ultra-high field (7T) magnets. Several studies have already investigated carotid vessel wall imaging at 7T and compared it with state-of-the-art 3T protocols. These initial investigations have focused on 2 dimensional (2D), multi-slice imaging. Better than this approach, 3 dimensional (3D) vessel wall imaging allows characterizing extensive vascular territories while minimizing partial volume artifacts in plaque-prone regions, such as the carotid bulb and bifurcation. Here, we demonstrated the feasibility of performing 3D carotid vessel wall imaging on a whole body 7T clinical magnet using a custom made carotid coil.
