本文用经颅多普勒超声对４００例正常成人大脑中动脉（ＭＣＡ）与颈动脉流速比值进行测定，探讨国人不同年龄、不同性别的ＭＣＡ与颈内动脉颅外段近端（ＰＩＣＡ）、ＭＣＡ与颈总动脉近端（ＰＣＣＡ）、ＰＩＣＡ与ＰＣＣＡ血流速度比值的正常参考值及与临床的关系。资料与...
In this paper, the transcranial Doppler echocardiography was used to determine the ratio of MCA to carotid artery velocity in 400 normal adults. The relationship between MCA and carotid artery intima-mediastinal (PICA), MCA And proximal carotid artery (PCCA), PICA and PCCA blood flow velocity ratio of the normal reference value and the clinical relationship. Data and ...
