摘　　要：目的探讨经颅多普勒超声(TCD)检查预测脑血管狭窄的价值。方法选取某社区医院2014-03—2016-09门诊及病房疑似或确诊脑血管病患者为研究对象。所有研究对象首先进行TCD检查,然后进行头颅磁共振血管造影(MRA)或CT血管造影(CTA)确诊检查,计算两种检查方法的一致性,以及TCD检查的敏感性和特异性。结果 90例患者中,TCD检查阳性69例,阴性21例。头颅磁共振检查发现,TCD阳性组中确诊64例,TCD阴性组中确诊6例。TCD检查灵敏度为91.4%,特异度为75.0%,与脑血管狭窄金标准检测方法比较达到中高度一致,Kappa值为0.7。结论 TCD检查可以有效预测病人脑血管狭窄,为早期发现、预防、治疗脑血管病提供依据。Objective To explore the value of transcranial Doppler（TCD）examination in predicting cerebral vascular stenosis.Methods All patients or suspected patients who accepted TCD examination from March 2014 to September 2016 were selected in the outpatient and inpatient department of community health service center.After having receiving TCD examination,all subjects accepted MRA or CTA examinations to calculate the consistency of those two inspection methods and figure up the sensitivity and specificity of TCD examination.Results Among the selected 90 cases,TCD examination showed 69 positive cases and 21 negative cases.MRI examination confirmed 64 cases in TCD-positive group and 6cases in TCD-negative group.The sensitivity of TCD examination was 91.4% and specificity was 75.0%,which indicated that TCD examination reached intermediate-high level in comparison to gold standard used for inspecting cerebral vascular stenosis（Kappa=0.7）.Conclusion TCD examination can be used to predict cerebral vascular stenosis and can provide references for early detection,prevention and treatment.
