Relationship between HR-MRI Features and Stroke Risk in Patients with Symptomatic Intracranial Artery Stenosis
Objective To analyze the relationship between high-resolution magnetic resonance imaging(HR-MRI)features and stroke risk in patients with symptomatic intracranial artery stenosis.Methods 87 patients with symptomatic intracranial artery stenosis admitted to the hospital from May 2021 to July 2022 were selected.Three patients with poor image quality were excluded,and 84 patients were finally included in the study.According to the diagnostic criteria for ischemic stroke,38 patients and 46 patients were included in the stroke group and the non-stroke group,respectively.Baseline data and HR-MRI features of the two groups were comparatively analyzed.The relationship between HR-MRI features and stroke risk was discussed.Results The two groups had comparable baseline data(P＞0.05).Compared with the non-stroke group,plaque load and luminal stenosis rate were significantly higher in the stroke group(P＜0.05).Patients with fibrous cap and intra-plaque hemorrhage were significantly more in the stroke group(P＜0.05).Logistic regression analysis found that plaque load,luminal stenosis rate,fibrous cap and intra-plaque hemorrhage were influencing factors of stroke in patients with symptomatic intracranial artery stenosis(P＜0.05).Conclusion HR-MRI features such as plaque load,luminal stenosis rate,fibrous cap,and intra-plaque hemorrhage are influencing factors of stroke in patients with symptomatic intracranial artery stenosis,which deserves close attention in clinical treatment.
