摘　　要：目的:研究磁敏感加权成像(Susceptibility-Weighted Imaging,SWI)在预测急性脑梗塞患者静脉溶栓血管再通效果中的应用价值。方法:选取2020年3月至2024年6月期间在我院接受静脉溶栓治疗的急性脑梗塞患者60例,分为阳性组和阴性组,各30例。根据SWI扫描结果比较两组患者的血管再通率、临床症状改善情况及并发症发生率。结果:阳性组的血管再通率为86.7%,显著高于阴性组的50.0%(P<0.05)。阳性组临床症状显著改善率为80.0%,高于阴性组的40.0%(P<0.05)。并发症发生率方面,阳性组为13.3%,低于阴性组的40.0%(P<0.05)。结论:SWI在预测急性脑梗塞静脉溶栓治疗效果中具有重要的临床应用价值,能够提高血管再通率、改善患者预后并减少并发症,具有广泛的临床推广价值。Objective:To study the application value of susceptibility-weighted imaging(SWI)in predicting the recanalization effect of intravenous thrombolysis in patients with acute cerebral infarction.Methods:Sixty patients with acute cerebral infarction who received intravenous thrombolysis at our hospital between March 2020 and June 2024 were selected and divided into two groups:the positive group and the negative group,with 30 cases in each.The recanalization rate,clinical symptom improvement,and incidence of complications were compared between the two groups based on SWI scan results.Results:The recanalization rate in the positive group was 86.7%,significantly higher than the 50.0%in the negative group(P<0.05).The rate of significant clinical symptom improvement in the positive group was 80.0%,higher than the 40.0%in the negative group(P<0.05).The incidence of complications in the positive group was 13.3%,lower than the 40.0%in the negative group(P<0.05).Conclusion:SWI has significant clinical value in predicting the effectiveness of intravenous thrombolysis in patients with acute cerebral infarction,as it improves the recanalization rate,enhances patient prognosis,and reduces complications,making it highly valuable for clinical promotion.
