The increasing understanding of atherosclerosis as an important risk factor for the development of acute ischemic events like ischemic stroke has stimulated increasing interest in non-invasive assessment of the structure, composition and burden of plaque depositions in the carotid artery wall. This requires the coverage of larger volumes, which, the often applied 2D dual inversion recovery (DIR) techniques are not able to deliver. However 3D protocols, because of the prolonged scan time, can lead to severe motion artifacts, e.g. from swallowing and the DIR black blood effect is prone to fail in the larger volumes due to saturation effects.
The purpose of this work was to develop a time efficient and robust 3D black blood technique to visualize large segments of the carotid arteries, centered on the location of the bifurcations, which are of special clinical interest for the assessment of atherosclerosis.
With the suggested dual-stack technique in combination with diffusion prepared black-blood imaging, high quality dark blood imaging of the carotid arteries over a large range appears feasible. This might enable fast overview scans for assessment of the plaque burden in atherosclerotic patients.
