摘　　要：目的探讨64层螺旋CT脑灌注联合CT血管造影对颈内动脉狭窄或闭塞的诊断价值。方法选取因颈内动脉狭窄或闭塞在我院进行治疗的80例患者,对其进行64层螺旋CT脑灌注、CT血管造影扫描。观察64层螺旋CT脑灌注的平均通过时间、对比脑血流量、脑血容量、对比剂峰值时间,观察血管造影后患者的劲内动脉狭窄程度。结果短暂性脑缺血发作、急性脑梗死患者患侧的对比剂峰值时间均明显长于健侧的对比剂峰值时间,差异有统计学意义(P<0.05)。结论采用64层螺旋CT脑灌注联合CT血管造影,能同时诊断颈内动脉狭窄或闭塞的脑部血流灌注及颈动脉狭窄的程度。Objective To discuss the diagnosis value of 64-slice spiral CT cerebral perfusion combined with CT angiography on internal carotid artery stenosis or occlusion.Methods Totally 80 cases of patients with internal carotid artery stenosis or occlusion admitted in our hospital were selected,and were done by 64-slice spiral CT brain perfusion and CT angiography scan.The mean transit time of 64-slice spiral CT cerebral perfusion was observed,and the cerebral blood flow,cerebral blood volume,and time to peak were contrasted.The carotid artery stenosis degree after angiography was observed.Results The peak time of ipsilatera of patients with transient ischemic attack and acute cerebral infarction was significantly longer than that of the contralateral,there was a significant statistical difference（P0.05）.Conclusion 64-slice spiral CT cerebral perfusion combined with CT angiography can diagnose internal carotid artery stenosis or occlusion and degree of carotid stenosis at the same time.
