摘　　要：目的:观察轻度认知障碍(MCI)的脑血流特点。方法:用德国EME公司生产的2021型经颅多普勒(TCD)仪,分别检测受试对象双侧大脑中动脉、大脑前动脉、椎动脉和基底动脉的峰值、均值及搏动指数。结果:与对照组比较,MCI患者双侧大脑中动脉、大脑前动脉、椎动脉和基底动脉的峰值、均值及搏动指数均无显著性差异。结论:MCI脑血流无明显病理变化。Objective To investigate the characteristics of cerebral blood flow in mild cognitive impairment（MCI）. Methods Objects were examined with 2021 TCD instrument produced by German EME Corporation. Peak velocity, mean velocity and pulsatility index of bilateral middle cerebral arteries, anterior cerebral arteries, vertebral arteries and basilar arteries were observed respectivily. Results Compared with control group, peak velocity, mean velocity and pulsatility index of bilateral middle cerebral arteries, anterior cerebral arteries. vertebral arteries and basilar arteries in MCI had no significant difference. Conclusion There were not obvious change in cerebral blood flow in MCI.
