Application of 3.0T High-resolution Magnetic Resonance Imaging in Plaque Assessment in Patients with Post-circulation Ischemic Stroke
Objective To investigate the effect of 3.0T high resolution magnetic resonance imaging(HR-MRI)on plaque evaluation in patients with posterior circulation ischemic stroke.Methods Clinical data of 83 patients with post-circulation ischemia admitted to the First Affiliated Hospital of Hebei North University from May 2021 to April 2023 were retrospectively analyzed.All patients underwent 3.OT HR-MRI examination.According to whether the patients had post-circulation ischemic stroke,they were divided into post-circulation ischemic stroke group(n=43)and non-stroke group(n=40).MRI angiography and high-resolution T1-weighted imaging(T1WI)were used to observe and measure the plaque vascular stenosis,plaque distribution and characteristics of the two groups.The degree of arterial stenosis,plaque distribution,plaque load,plaque signal,plaque morphology,plaque enhancement,plaque thickness and plaque volume were compared between the two groups.Results There was no significant difference in the distribution of posterior arterial plaque between the stroke group and the non-stroke group(P＞0.05),and the degree of arterial stenosis was higher than that of the non-stroke group(P＜0.05).The plaque load,plaque thickness and plaque volume in the stroke group were higher than those in the non-stroke group(P＜0.05),the proportion of plaque enhancement and the proportion of high signal in the plaque were higher than those in the non-stroke group(P＜0.05),and there was no statistical significance in plaque morphology between the two groups(P＞0.05).The ratio of the thickest point of plaque on the left and right lateral wall in the stroke group was higher than that in the non-stroke group(x 2=5.846,P＜0.05),and the ratio of the thickest point of plaque on the venstral wall and the dorsal wall had no statistical significance between the two groups(P＞0.05).Conclusion The degree of arterial stenosis is more significant in patients with post-circulation ischemic stroke,and atherosclerotic plaque load,plaque enhancement and intracavicular high signal are relatively common.3.OT HR-MRI is beneficial for evaluating plaque characteristics in patients with post-circulation ischemic stroke.
