多模式磁共振检查对急性脑卒中患者的应用价值

Application value of multimodal magnetic eesonance inspection in patients with acute stroke

目的:探讨多模式MR检查对急性脑卒中患者的应用价值。方法:选取临床拟诊为急性脑卒中的194例患者的CT和多模式MR影像,对比CT和多模式MR对急性脑梗死、陈旧性脑出血、急性脑出血、蛛网膜下腔出血、动脉瘤、动静脉畸形、脑微出血的检出率。结果:194例患者,CT与多模式MR对急性脑梗死、陈旧性脑出血、急性脑出血、蛛网膜下腔出血、动脉瘤、动静脉畸形、脑微出血的检出率分别为(26.8%VS 54.1%、5.7%VS 5.7%、27.3%VS 27.3%、7.7%VS 7.7%、0 VS 9.8%、0 VS 1.0%、0 VS 22.7%),CT不能显示脑微出血。T2WI与DWI对急性脑梗死的检出率分别为29.4%VS 54.1%,差异有统计学意义(P<0.05)。T2~*梯度回波序列(T2~*GRE)检出44例脑微出血,常规MR未能检出。结论:对于急性脑卒中患者,多模式MR检查可在短时间内为临床提供较全面的影像信息制定治疗方案。

Objective To explore the application value of multimodal magnetic resonance(MR)inspection on patients with acute stroke.Methods CT and multimodal MR images from 194 possible acute stroke patients were selected to compare the detection rates of acute cerebral infarction,obsolete cerebral hemorrhage,acute cerebral hemorrhage,subarachnoid hemorrhage,arterial aneurysm,arteriovenous malformation(AVM)and cerebral microbleeds(CMBs)between CT and multimodal MR.Results The detection rates of acute cerebral infarction,obsolete cerebral hemorrhage,acute cerebral hemorrhage,subarachnoid hemorrhage,arterial aneurysm,AVM and CMBs in 194 patients between CT and multimodal MR were 26.8%VS 54.1%,5.7%VS 5.7%,27.3%VS 27.3%,7.7%VS 7.7%,0 VS 9.8%,0 VS 1.0%and 0 VS 22.7%,respectively.CT could not display CMBs.Meanwhile,the detection rates of acute cerebral infarction between T2 WI and DWI were 29.4%VS 54.1%,with the difference being statistically significant(P<0.05).CMBs could be detected through T2*GRE in 44 cases,which could not be detected through conventional MR.Conclusion For patients with acute stroke,multimodal MR examination can provide comprehensive imaging information in a short period of time,which can be used to formulate treatment plans.
