High-resolution, volumetric carotid vessel wall imaging
is a promising method for the rapid assessment of plaque
burden. Such an imaging procedure, however, is
frequently challenged by complex motions in the
carotids, including pulsation of carotid arteries,
swallowing, breathing, and bulk motion of patient. The
goal of this work is to develop a motion-robust,
black-blood 3D carotid wall imaging technique using a
stack-of-stars sampling scheme. The efficacy of using
such a method is compared to the conventional carotid
wall imaging with Cartesian sampling. Volunteer studies
show improved image quality and vessel wall delineation
using the proposed flow-sensitive dephasing prepared
stack-of-stars sequence.
