【摘要】 应用经颅多普勒超声（ＴＣＤ）、数字减影血管造影（ＤＳＡ）、磁共振血管成像（ＭＲＡ）、ＣＴ血管造影（ＣＴＡ）对２４例蛛网膜下腔出血（ＳＡＨ）病人进行了对照研究。通过ＴＣＤ诊断血管痉挛和狭窄性病变１９例（７９％），治疗前后动态观察发现脑底动脉平均流速（Ｖｍ）增高。诊断颅内压增高２例（８．３％）Ｖｍ降低。血管造影等放射影像学检查，发现动脉瘤８例，动脉炎样改变６例，动脉痉挛２例，正常者８例，总异常率为６６．６％。通过超声与放射影像学比较发现，两者可以从不同角度显示脑血管的功能或病理状态。更多还原

【Abstract】 Twentyfour subarachnoidal haemorrhages (SAH) patients were examinated by TCD,MRA,CTA.Motive TCD showed 19 cases diagnosed as vasospasm and stenosis with the increased Vm(79%),2 cases of increased cranial pressure,with decreased Vm(8.3%).8 cases were diagnosed as aneurysma, 6 cases as arteritis, 2 vasospasm and 8 normal, verified by neuroimaginal examination. The abnormility rate was 66.6%. The function and pathological staus of cerebral vessel can be tested through the examination of ultralschall and radialimaging techniques.更多还原
