摘　　要：目的 了解急性缺血性脑卒(AIS)患者脑CT灌注成像-CT血管造影(CTP-CTA)参数及其对脑损伤判断价值。方法 60例AIS患者进行CTP-CTA,分析CTP-CTA参数对脑损伤判断价值。结果 51例(85.0%)患者显示灌注异常。重度缺损组的脑血容量、脑血流量、强化峰值低于轻中度缺损组,峰始时间和达峰时间则高于轻中度缺损组(P<0.05)。结论 CTP-CTA参数对AIS患者脑损伤具有较好的判断价值。Objective To analyze the parameters of CT perfusion(CTP)-CT angiography(CTA) for evaluating brain injury in patients with acute ischemic stroke(AIS). Methods The parameters of CTP-CTA and their assessment on brain injury were analyzed in 60 AIS patients. Results Abnormal cerebral perfusion occurred in 51 cases(85.0%). Compared with mild and moderate defect groups, cerebral blood flow/volume and peak enhancement were lower, while time to start/peak was higher in severe defect group(P<0.05). Conclusion The parameters of CTP-CTA are helpful for judging brain injury in patients with AIS.
