[Abstract] Objective: To explore the relationship between the enhancement degree of atherosclerotic plaque and vascular remodeling in middle cerebral artery (MCA) and the number and depth of lenticulostriate artery by high-resolution magnetic resonance imaging(HR-MRI).Materials and Methods: 40 patients with symptoms and 40 patients without symptoms were enrolled in this study. All subjects underwent 3D-T1WI-VISTA sequence imaging with HR-MRI. Subjects'high resolution angiographic data were transmitted to the post-processing workstation. Philips Intellispace portal software was used to calculate the plaque enhancement index and lumen remodeling index of middle cerebral artery and the number and depth of lenticulostriate artery. SPSS 25.0 software was used to analyze the plaque enhancement index and lumen remodeling index of middle cerebral artery (MCA) and the depth and number of lenticulostriate artery (LSA) in two groups.Results: Compared with the asymptomatic group, the symptomatic group had higher enhancement index of middle cerebral artery atherosclerotic plaque (P<0.05) and shorter lengths of striated arteries than the asymptomatic group (P<0.05). There was no significant difference between symptomatic group and asymptomatic group in the lumen remodeling index of middle cerebral artery and the number of lenticulostriate artery (P>0.05).Conclusions: There was a certain difference between symptomatic group and asymptomatic group in the degree of enhancement of middle cerebral artery atherosclerotic plaque and the depth of lenticulostriate artery. High resolution magnetic resonance angiography has clinical value in evaluating middle cerebral artery atherosclerotic plaque.
