摘要
目的分析高分辨磁共振扫描对急性脑梗死患者大脑中动脉血管壁及、斑块特征分析的应用。方法选择2022年1月至2023年1月于我院收治的急性脑梗死患者58例为急性脑梗死组,同期选择短暂性脑缺血患者46例为短暂性脑缺血组,两组患者均行高分辨磁共振检查,比较两组患者大脑中动脉血管壁斑块特征、性质及相关参数,采用受试者工作特征(RDC)曲线评估高分辨磁共振参数诊断急性脑梗死的价值。结果急性脑梗死组患者斑块位置(腹侧壁、上侧壁)、狭窄重构方式(负性)、斑块表面形态(不平整)比例明显高于短暂性脑缺血组,差异具有统计学意义(P<0.05)。急性脑梗死组患者血管最狭窄处管腔面积(LAmln)水平明显低于短暂性脑缺血组,管壁面积(WAmln)、斑块负荷、狭窄率、斑块面积水平明显高于短暂性脑缺血组,差异具有统计学意义(P<0.05)。急性脑梗死组、短暂性脑缺血组患者斑块类型差异无统计学意义(P>0.05)。ROC曲线分析结果显示,LAmln、WAmln、斑块负荷、狭窄率、斑块面积诊断急性脑梗死的曲线下面积(AUC)分别为0.737、0.828、0.779、0.821、0.936(P均<0.05)。结论急性脑梗死患者高分辨磁共振扫描斑块多出现在腹侧壁、上侧壁部位,狭窄呈负性重构、斑块表面形态不平整,LAmlm、WAmlm、斑块负荷、狭窄率、斑块面积呈明显异常表达,在诊断急性脑梗死方面具有一定价值。
Objective To analyze the application of high-resolution magnetic resonance scanning for the analysis of middle cerebral artery vessel wall and,plaque characteristics in patients with acute cerebral infarction.Methods Fifty-eight patients with acute cerebral infarction admitted to our hospital from January 2022 to January 2023 were selected as the acute cerebral infarction group,and 46 patients with transient cerebral ischemia were selected as the transient cerebral ischemia group during the same period,and both groups underwent high-resolution magnetic resonance examination to compare the plaque characteristics,nature and related parameters of the middle cerebral artery vascular wall in both groups,and the subject operating characteristic(ROC)curve was used to assess the value of high-The value of high-resolution MRI parameters for the diagnosis of acute cerebral infarction was evaluated by using the subject operating characteristic(ROC)curve.Results The proportions of plaque location(ventral and superior lateral walls),stenosis remodeling mode(negative),and plaque surface morphology(unevenness)were significantly higher in patients in the acute cerebral infarction group than in the transient cerebral ischemia group,with statistically significant differences(P<0.05).The level of lumen area at the narrowest part of the vessel(LAmln)was significantly lower in the acute cerebral infarction group than in the transient cerebral ischemia group,and the level of wall area(WAmln),plaque load,stenosis rate,and plaque area were significantly higher than in the transient cerebral ischemia group,with statistically significant differences(P<0.05).The differences in plaque types between patients in the acute cerebral infarction group and transient cerebral ischemia group were not statistically significant(P>0.05).the results of ROC curve analysis showed that the area under the curve(AUC)of LAmln,WAmln,plaque load,stenosis rate,and plaque area for the diagnosis of acute cerebral infarction were 0.737,0.828,0.779,0.821,and 0.936,respectively(all P<0.05).Conclusion High-resolution magnetic resonance scan plaques in patients with acute cerebral infarction were mostly found in the ventral and superior lateral wall areas,with negative remodeling of stenosis,uneven plaque surface morphology,and significant abnormal expression of LAmln,WAmln,plaque loading,stenosis rate,and plaque area,which have some value in the diagnosis of acute cerebral infarction.
