摘　　要：目的探讨弥散加权成像(DWI)联合磁敏感加权成像(SWI)诊断急性缺血性脑梗死的临床应用价值.方法回顾性分析32例急性脑梗死患者DWI及SWI影像表现.结果32例患者DWI序列上信号均升高,ADC图为低信号;SWI序列上20例发现脑膜侧侧支循环扩张的血管影,8例发现责任血管内低信号结节血栓影,12例合并脑微出血(其中4例为发病严重者脑内弥漫性分布,1例发生出血性转化).结论急性脑梗死患者DWI及SWI序列具有典型影像学表现,能为临床制定个体化精准治疗提供重要依据,可作为急性脑梗死患者影像学评估手段之一.Objective To investigate the clinical value of DWI combined with SWI in the diagnosis of acute ischemic cerebral infarction.Methods The DWI and SWI images of 32 patients with acute cerebral infarction were retrospectively analyzed.Results In 32 patients,the signal on the DWI sequence was increased,and the ADC map was low.On the SWI,20 cases(20/32)found vasculature of the meningeal collateral circulation,8 cases(8/32)found thrombus shadows of intravascular low-signal nodules,and 12(12/32)cases found cerebral microbleeds(4 of them were severe morbidity with diffusely distribution,and 1 of them found hemorrhagic transformation).Conclusion DWI and SWI sequences in patients with acute cerebral infarction have typical imaging appearances,which can provide primary basis for the individualized and precise treatments.It can be used as one of the imaging evaluation methods for patients with acute cerebral infarction.
