The
purpose was to evaluate the efficiency of carotid plaque MRI in
stent-treatment decision for patients with carotid atherosclerosis comparing
with DSA. A total of 17 symptomatic and 37 asymptomatic carotid arteries were
evaluated by MRI and DSA. Images were evaluated for luminal stenosis and
fibrous cap (FC) rupture, and the stent treatment decision was based on these
criterions. Intraplaque hemorrhage and calcification were also evaluated by
MRI. The result was that MRI was superior to DSA in determining stent
treatment, especially for asymptomatic patients with carotid artery narrowing
of less than 70% for its ability to detect FC rupture.
