![]() ![]() ![]() To improve blood suppression, flow-dephasing BB imaging techniques, such as the motion-sensitization driven equilibrium (MSDE) sequence, have recently been utilized for carotid artery vessel wall imaging ( 10– 12). Widely used BB imaging techniques such as in-flow saturation (IS) ( 5) and double inversion recovery (DIR) based ( 6– 9) techniques are limited by the blood replenishing rate and therefore prone to flow artifacts in the presence of recirculating or stagnant flow. Due to the complicated flow patterns in the carotid artery bifurcation, however, current black-blood (BB) imaging techniques are frequently compromised by plaque-mimicking artifacts ( 4). Efficient flowing blood signal suppression is critical for accurate morphology measurements and diagnosis in MR vessel wall imaging ( 1– 3). ![]()
