Multicontrast-weighted MRI is promising for characterization of carotid plaques, but is hampered by motion artifacts. This study demonstrated initial feasibility of motion-compensated carotid-MRI achieved by a novel approach to FID-based navigator gating. The results demonstrate the potential of the proposed gating-approach to improve the clinical capability of MR imaging of carotid plaques.
