摘要
目的:研究磁共振SWI和PWI在急性缺血性脑梗死缺血半暗带量化评定中的应用。方法:选择自2019年6月至2020年8月来我院就诊的124例急性缺血性脑梗死患者作为本次研究对象,采用数字表法将124例患者随机平均分为A组和B组,每组62例。A组进行磁共振SWI扫描,B组进行磁共振PWI扫描。对比两组对急性缺血性脑梗死缺血半暗带量化评定结果。结果:A组检出率小于B组检出率,但两组差异无统计学意义(P>0.05);A组病灶检出率低于B组,两组差异有统计学意义(P<0.05)。结论:SWI对急性缺血性脑梗死患者缺血半暗带整体检出率与PWI没有明显差异,说明SWI可以用于急性缺血性脑梗死患者脑梗死半暗带筛查,且与PWI相比对人体损伤较小,有推广应用的价值。
Objective:To study the application of SWI and PWI in quantitative assessment of ischemic penumbra in acute ischemic cerebral infarction.Methods:124 patients with acute ischemic cerebral infarction from June 2019 to August 2020 in our hospital were selected as the research objects,and they were randomly divided into group A and group B with 62 cases in each group.Group a underwent SWI and group B underwent PWI.The quantitative evaluation results of ischemic penumbra in the two groups were compared.Results:the detection rate of group A was lower than that of group B,but there was no significant difference between the two groups(P>0.05);The detection rate of lesions in group A was lower than that in group B,and the difference was statistically significant(P<0.05).Conclusion:there is no significant difference between SWI and PWI in the detection rate of ischemic penumbra in patients with acute ischemic cerebral infarction,indicating that SWI can be used to screen ischemic penumbra in patients with acute ischemic cerebral infarction,and has less damage to human body compared with PWI,which has the value of popularization and application.
