We present a prospectively accelerated 3D black-blood sequence in conjunction with CS reconstruction and show the feasibility of 3D high-resolution carotid vessel wall imaging. Results show that acceleration in combination with CS reconstruction increased SNR efficiency and resulted in improved vessel wall visibility as compared to the full data acquisition. More importantly, high-resolution imaging carotid imaging (0.4-0.5 mm) was shown feasible within a clinically feasible imaging time of 4 min.
