摘要: 目的探讨多层螺旋CT(MSCT)脑灌注成像及头颈部CT血管造影(CTA)在临床诊治短暂性脑缺血发作(TIA)中的应用价值。方法对发病时间≤48h的20例临床诊断为TIA患者应用16排螺旋CT依次进行头颅CT平扫、脑MSCT灌注成像(CTPI)及头颈部CTA检查,观察测量脑内感兴趣区的脑血流量(rCBF)、脑血容量(rCBV)、达峰值时间(rTP),并与CTA结果进行相关分析。结果与临床症状相对应的灌注异常区与对侧相比,CTPI表现为患侧rTP延迟(t=3.04,P=0.008),CTA表现为责任血管的不同程度的狭窄或闭塞。但两者间无明确相关性(r=0.32,P=0.17)。结论脑灌注成像能够提供脑血流动力学异常的信息,配合头颈部CTA了解其责任血管情况,具有临床应用价值。

Abstract: Objective To use the multi-slice CT(MSCT)cerebral perfusion imaging and CT angiography(CTA)in the clinical diagnosis of transient ischemic attack(TIA).Methods 20 cases with transient ischemic attack within 48 h were examined with 16-slice CT perfusion imaging(CTPI)and CTA in head and neck.The interesting regional cerebral blood flow(rCBF),cerebral blood volume(rCBV)and the time to peak(rTP)were analyzed.Results The rTP of affected side delay compared with that of the healthy(t=3.04,P=0.008).CTA showed the responsible vascular stenosis or occlusion in varying degrees.There was not significant correlationship between rTP and vascular stenosis(r=0.32,P=0.17).Conclusion Cerebral perfusion imaging and head and neck CTA can provide valuable information for diagnosis and treatment of TIA.
