Weiwei? ? WANG? Suping First Department of Neurology，Dalian Municipal Central Hospital，Dalian 116033，China [Abstract] Objective To evaluate the reliability of transcranial doppler（TCD）in diagnosing internal carotid artery, middle cerebral artery stenosis of cerebral infarction patients. Methods There were 45 patients with cerebral infarction who were treated in our department between 2011 June to 2012 August. They were underwent TCD and CTA examination within 1 week after hospitalization（time interval in 3 days）. Results According to CTA results，the sensitivity of TCD in diagnosing internal carotid artery stenosis（occlusion, severe and moderate stenosis）was 47.1%, the specificity was93.2%, the coincidence was 84.4%；The se
