MRI-based vessel imaging has two goals, the anatomico-morphological depiction and vessel wall imaging, including delineation of contrast enhancement within the vessel wall. We performed sequence implementation and optimization in healthy volunteers to establish a dedicated 7T MRI protocol for vessel imaging at 7T. We implemented MPRAGE, T2 TSE, SWI, and ToF for anatomico-morphological vessel-delineation and optimized T1 SPACE and T1 SE for vessel wall delineation.
