目的探讨二维血流显像技术在诊断椎动脉（VA）疾病中的应用价值。方法本组对80例脑梗塞、糖尿病和冠心病等血管疾病多发人群，分别进行双侧椎动脉CDFI、PDI及B-Flow检查，观察椎动脉形态、走行，管壁厚度，管腔内血流情况，并进行血流动力学检测。结果根据所测内膜、内径和斑块等图像特征，可以反映椎动脉硬化及狭窄等情况。B-Flow显像是一种新型血管疾病影像学检查方法，能同时显示血流和背景组织结构，与CDFI、PDI结合使用，能清晰显示异常影像，提高椎动脉疾病诊断率。结论在椎动脉疾病的检查中，B-Flow是一种有效的辅助检查方法。%Purpose To evaluate the value of using the B-flow technique indiagnosis of vertebral artery（VA） diseases.Methods 80 cases of patients with cerebral vessels' stroke,diabetes and cornary heart disease were examined by using the techniques of B/W,CDFI,PDI and B-flow.The wall thickness,blood stream and hemodynimic of VA were observed.Results According to the characteristics of image such as diameter intimate-medial wall thickness and arteriosclerotic plaques,can reflect VA arteriosclerosis,straitness etc.B-flow can display blood flow and tissue structure around the vessels such as wall of vessels,artery membrane simultaneously.It can display abnormal image clearly in combined with CDFI,PDI.Conclusion B-Flow technique is an effective methods in detecting disease of VA.
