摘　　要：探讨超声ET技术对颈动脉弹性功能的检测及不同年龄组颈动脉弹性值。应用ET技术检测145人颈动脉的β、Eρ、AC、AI及PWVβ，年龄22～84岁，平均47．0岁，男75例，女70例。年龄分5组：20～29岁，30～39岁，40~49岁，50~59岁，≥60岁。比较各年龄组左右两侧、男女之间及各组间动脉弹性的差异。左右两侧及性别之间颈动脉弹性指标无差异；随着年龄的增高，β、Eρ、AI、PWVβ增高，AC降低。正常人群不同年龄组的左右两侧及男女之间颈动脉弹性无差异；随着年龄的增高，颈动脉的弹性降低；ET技术可以敏感检测颈动脉的弹性功能状态。This investigation was amied to detect the carotid elasticity in normal adults by use of echo-tracking （ET） technique. The stiffness parameter （β）, pressure-strain elasticity modulus {Eρ）, arterial compliance（AC）, argumentation index（AI） and one-point pulse wave velocity （PWVβ） of carotid in 145 normal adults with the average age of 47.0 were calculated. The population were divided into five groups according to age： 20- 29y, 30- 39y, 40- 49y, 50- 59y and≥ 60y. The elasticity parameters between left and fight side, between male female and between different age groups were compared using SAS 6.12 statistic software. There was no difference in carotid elasticiw regarding the side and gender. The carotid β, Eρ, AI and PWVβ were noted to increase with age while AC was noted to decrease with age. The carotid elasticity was found to correlate with age significantly, but not with side and gender. This change can be detected by ET technique.
