摘要
目的探讨缺血性脑卒中患者液体衰减反转恢复(fluid-attenuated inversion recovery,FLAIR)序列远端血管高信号(FLAIR vascular hyperintensity,FVH)与扩散加权成像(diffusion weighted imaging,DWI)梗死灶之间匹配性是否可以判断患者临床预后情况。材料与方法对34例大脑中动脉闭塞的缺血性脑卒中患者行常规颅脑MRI、磁共振血管造影(magnetic resonance angiography,MRA)和DWI扫描,依据FVH和DWI之间的关系分为FVH-DWI匹配组和FVH-DWI不匹配组,并随访患者进行了90 d改良Rankin量表(mRS)评估。结果FVH-DWI匹配和FVH-DWI不匹配两组患者在90 d mRS评分及90 d mRS≤2(预后良好)的差异均无统计学意义(P>0.05)。结论FVH-DWI是否匹配不能预测缺血性脑卒中患者90 d临床预后结果。
Objective:To investigate whether the prognosis of patients with ischemic stroke can be determined by the match between distal vascular hypersignal(FVH)of FLAIR sequence and DWI infarction.Materials and Methods:Thirty-four patients with ischemic stroke with middle cerebral artery occlusion received routine craniocerebral MRI,MRA and DWI scans.According to the relationship between FVH and DWI,they were divided into the FVH-DWI match group and the FVH-DWI mismatch group.Results:There was no statistically significant difference between the FVH-DWI match and FVH-DWI mismatch in mRS score at 90 days and mRS≤2 at 90 days(good prognosis)between the two groups(P>0.05).Conclusions:The match of FVH-DWI could not predict the clinical prognosis of ischemic stroke patients on 90 days.
