目的　探讨脑梗死患者脑CT与血粘度、经颅多普勒 (TCD)之间的关系。方法　对经过脑CT证实的 80例脑梗死患者分别进行TCD及血粘度检查。正常对照组 76例。结果　脑梗死组TCD示血流异常率 90 %。血粘度改变为 90 %。结论　TCD、血粘度、脑CT均对脑梗死的诊断有重要应用价值 Objective To investigate the relationship between cerebral CT and blood viscosity and transcranial Doppler (TCD) in patients with cerebral infarction. Methods TCD and blood viscosity were examined in 80 patients with cerebral infarction confirmed by brain CT. 76 cases of normal control group. Results TCD showed cerebral infarction group abnormal blood flow rate of 90%. Change in blood viscosity to 90%. Conclusion TCD, blood viscosity, brain CT are important for the diagnosis of cerebral infarction
