【摘要】：目的:应用3.0T高场和高分辨率磁共振成像技术检查有症状的颅内大脑中动脉粥样硬化性斑块是否存在、形态及斑块增强度,评估斑块稳定性与脑梗死发生的关系。材料和方法:回顾性分析60例动脉粥样硬化性大脑中动脉的成像和临床数据,高分辨率T_1WI显示斑块形态并测量斑块增强度和垂体增强度,两者之间比较分为3组:明显强化、轻度强化和无强化。结果:60例有症状的患者纳入统计,45例为偏心性斑块,研究19例急性期、14例亚急性期、15例慢性期和12例无脑梗死病灶的大脑中动脉斑块增强度,斑块增强度与垂体增强度间斯皮尔曼相关系数及P值有统计学意义。结论:大脑中动脉粥样硬化性斑块呈偏心性比较常见,斑块强化程度与斑块稳定性、脑梗死发生率之间有密切的关系,这两点相结合可用于与其他血管性病变相鉴别。
[Abstract]:Objective: to evaluate the relationship between plaque stability and cerebral infarction by using 3.0T high-field and high-resolution magnetic resonance imaging (HRMRI) to detect the presence, morphology and enhancement of atherosclerotic plaques in the symptomatic middle cerebral artery.Materials and methods: the imaging and clinical data of 60 patients with atherosclerotic middle cerebral artery were analyzed retrospectively. High-resolution T_1WI showed plaque morphology and measured plaque enhancement and pituitary enhancement.Mild and no enhancement.Results among 60 symptomatic patients, 45 patients were diagnosed as eccentric plaques. The enhancement degree of plaque in middle cerebral artery was studied in 19 patients with acute phase and 14 patients with subacute phase, 15 patients with chronic stage and 12 patients with no cerebral infarction lesions.The correlation coefficient and P value between plaque enhancement and pituitary enhancement were statistically significant.Conclusion: Atherosclerotic plaques in the middle cerebral artery are more common in eccentricity. The degree of plaque enhancement is closely related to the plaque stability and the incidence of cerebral infarction, which can be used to differentiate the plaque from other vascular lesions.
