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.
