The purpose is to evaluate the carotid plaque component evaluated by MR plaque image as the finding to predict the complication risk at carotid artery stenting (CAS). Thirty-one carotid plaques of 30 patients were classified to stable and vulnerable groups and compared with the occurrence of slow flow phenomenon as indicator of embolic complication risk and there was significant difference (P<0.05) on chi-square test. The carotid plaque classified the composition as vulnerable by MR plaque image has the significant higher risk of slow flow phenomenon at CAS. The complication risk at CAS can be predicted by MR plaque image.
