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.
