Imaging of the atherosclerotic vessel wall requires acquisition with high in plane spatial resolution, high SNR and CNR. On 1.5T and 3T scanners these parameters can be optimized at the expense of acquisition time, which renders imaging protocols unfeasible. Here we present a feasibiltiy study for imaging the abdominal aorta of atherosclerotic rabbits at 7T, and compare SNR and CNR with 1.5 and 3T clinical scanners.
