目的探讨血管回声跟踪技术(ET)对不同年龄组男性飞行员颈动脉血管弹性的定量检测功能。方法应用ET技术检测72例男性飞行员的颈动脉血管,根据年龄不同分为3组,并参照国人颈动脉弹性正常测量值对各年龄组与正常人的血管弹 Objective To investigate the quantitative detection of carotid artery elasticity of male pilots in different age groups by using vascular echo tracing technique (ET). Methods The ET technique was used to detect the carotid arteries of 72 male pilots. The carotid arteries were divided into 3 groups according to their age. The blood vessels of all age groups and normal people
