摘　　要：目的　评价头部CT、CTA、CTP3项联合检查对缺血性脑血管病诊断价值。方法　对70例患者进行3项联合检查。结果　12例TIA患者中,半球腔隙性梗死3例,9例血管病变,4例CTP显示血流灌注异常。2 9例椎基底动脉供血不全患者,1例枕叶梗死,4例基底节腔隙性梗死,椎基底动脉系血管病变2 7例,6例血流灌注异常。2 9例脑梗死患者中,2例超早期CT未见异常,检出MCA闭塞和供血区血流灌注减低,余2 7例(含腔隙性脑梗死12例)中,检出动脉病变2 5例,血流灌注减低区15例。结论　对TIA及椎基底动脉供血不全的患者,3项联合检查可提供有价值的诊断资料,并能指导溶栓治疗。Objective To evaluate the diagnostic value of comprehensive CT imaging in patients with ischemic CVD.Methods CT、CTA and CTP were performed with multisection spiral CT in 70 patients.Results In 12 TIA patients,CTA detected ICA、MCA stenosis or occlusion in 7 and atherosclerosis in 2 cases.CTP showed hypoperfussion area in 4 cases.In 29 patients with vertebro-basilar arterial (VB) insufficiency,CTA detected VA stenosis or PCA stenosis in 27 cases,CTP revealed hypoperfusion area in VB territory in 6 cases.In 29 patients with CI,two was examined in extra early stage in which CT did not show infarction,CTA showed MCA occlusion,CTP showed hypoperfusion area in MCA territory.In other 27 cases,CTP revealed hypoperfusion area in 15 cases.CTA revealed abnormal cerebral artery in 25 cases.Conclusion Multisection spiral CT allows combined use of CT、CTA、CTP which provide important information for diagnosis of TIA and VB insufficiency and to choose suitable therapy,such as thrombolysis for patients with acute ischemic stroke.
