摘　　要：目的了解蛛网膜下腔出血后脑血管痉挛患者CT灌注成像的表现。方法将蛛网膜下腔出血患者16例分为症状性血管痉挛组和非血管痉挛组各8例,在出血后第1、7、12d行多排CT灌注成像,测量目的区域脑血容量(CBV)、脑血流量(CBF)、平均通过时间(MTT)值,两组之间参数相互比较。结果症状性血管痉挛组患者在发病后1、7d MTT值延长,和非痉挛组之间差异有统计学意义(P<0.05),CBV、CBF参数在两组之间无统计学意义(P>0.05)。结论 MTT时间延长是蛛网膜下腔出血后发生血管痉挛的一个预测参数。Objective To observe the characterization of perfusion CT（CTP） in patient after cerebral vasospasm secondary to subarachnoid hemorrhage.Methods 16 patients were divided into symptomatic cerebrovascular vasospasm group and no vasospasm groups.Cerebral blood flow（CBF）,cerebral blood volume（CBV）,and mean transit time（MTT） were measured with CT perfusion at first,7th and 12th day after SAH.Perfusion parameters including CBF,CBV and MTT were compared between two groups.Results MTT increased at first and 7th day after SAH in symptomatic cerebrovascular vasospasm group.There was no difference in the parameter of CBF and CBV between the two groups.Conclusion The delaying of MTT is a predictor of cerebrovascular vasospasm.
