摘    要:目的 分析急性缺血性卒中完全可逆性DWI高信号病例的临床与影像学特征。 方法 回顾性分析2012年1月-2015年12月的急性缺血性卒中完全可逆性DWI高信号病例9例,通过 基线与随访数据评估其临床与影像学特征。 结果 急性缺血性卒中完全可逆性DWI高信号病例基线NIHSS评分为1(1~2.5)分,基线DWI高信号 体积为0.94(0.28~2.39)mL,病变既见于皮层/皮层下,又见于深部白质,随访90 d的mRS评分为0 (0~1)分。 结论 急性缺血性卒中完全可逆性DWI高信号多见于轻型卒中,病灶梗死体积小,临床预后良好。

关 键 词:急性卒中  弥散加权成像  缺血  磁共振成像

Abstract:Objective To analyze the clinical and imaging characteristics in acute ischemic stroke (AIS)
patients with complete reversible DWI hyperintensities.
Methods Data of nine AIS patients with complete reversible DWI hyperintensities from January
2012 to December 2015 were collected retrospectively. Clinical and imaging characteristics in these
patients were evaluated through baseline and follow-up information.
Results The median baseline NIHSS was 1 (1-2.5), the mean baseline volume of DWI
hyperintensities was 0.94 (0.28-2.39) mL and the median mRS at 90 days was 0 (0-1) in the nine
patients. Complete reversible DWI hyperintensities could be found in cortex, subcortical white
matter, and deep white matter.
Conclusions Complete reversible DWI hyperintensities were usually found in minor stroke with
small infarct volume, and such patients usually had good clinical outcome.
Keywords:Acute stroke  Diffusion weighted imaging  Ischemia  Magnetic resonance imaging
