1·Methods 65 patients group and 26 control group were examined by MRA and TCD.
患者组65例，对照组26例，作磁共振血管成像和经颅多普勒检查。
2·Objective To explore the difference of TCD and CTA in diagnosis of MCA stenosis.
目的探讨经颅多普勒与CT血管造影对诊断大脑中动脉狭窄的异同。
3·Methods The brain blood flow of 4 cases who clinic diagnose were not clear was determined with TCD.
方法采用经颅多普勒仪，对4例临床诊断未明的病人进行脑血流动力学的检测。
4·CD on the day of admission, TCD yielded an abnormal rate of 91.3% in these patients, significantly higher than the rats by EEG (65.2%), topographic EEG mapping (78.3%) and head CT (17.4%).
入院当天经颅多普勒超声异常率91.3%，高于脑电图(65.2%)、脑电图地形图(78.3%)及头颅计算机断层扫描(17.4%)。
