High resolution MR imaging characteristics of the carotid atherosclerotic plaque
Abstract：Objective To investigate high resolution MRI sequence signal characteristics of the fi-brous cap and the intraplaque components of carotid atherosclerotic praque. Methods Four high resolution MRI sequences were used to analyze the carotid atherosclerotic plaques of 64 patients with carotid atherosclerotic plaque. The sequences used included 3D-TOF, T1WI, T2WI and PDWI. The patients were divided into transient ischemic attack(TIA) group containing 18 pa-tients and cerebral infarction(CI) group containing 46 patients. Results Of the sixty-four pa-tients, twenty-five had thick fibrous caps, twenty had thin fibrous caps, nineteen had ruptured fi-brous caps, fifty-three had lipid-rich necrotic cores, forty-four had calcification, thirty-one had in-traplaque haemorrhage, thirty-three had fibrous tissue in the plaque. There was no statistic differ-ence in plaque composition between the two groups. Conclusion The high resolution MRI can be used to examine the morphology and components of the plaque.
