Abstract: Objective To explore the remodeling modes and the plaque distribution of atherosclerotic BA at 3.0T high-resolution MRI.Methods 90 symptomatic patients with atherosclerotic stenosis of BA on digital subtraction angiography (DSA) (50%-99%) were recruited consecutively.Luminal area,vessel area of maximal narrow sites and the reference sites were measured.The differences of involved imaging parameters between negative group and positive group were analyzed.Results 51 patients with required imaging quality were enrolled finally.Among the 51 patients,the rate of positive remodeling cases was 72.5% (37/51) and negative remodeling took over 27.5% (14/51).Compared with the negative remodeling group,the positive remodeling group had greater plaque size,larger plaque burden percentage,and higher maximal wall thickness at maximal lumen narrowing sites.The plaques were mainly located at ventral wall of the vessel.Conclusion 3.0T high-resolution MR imaging could be applied in assessing the remodeling modes and plaque distribution of BA stenosis.
