Quantitative evaluation of common carotid arterial intima-media thickness and elasticity in healthy adults by ultrasound radio-frequency data technology / 中华超声影像学杂志

ABSTRACT

Objective To evaluate common carotid arterial intima-media thickness (IMT) and elasticity using ultrasound radio-frequency data (RF-data) technology, the normal values of the related parameters were determined in healthy adults for their potential clinical applications.Methods One hundred and sixty healthy adults were included and divided into 4 age groups with 20 males and 20 females in each group.The quantitative parameters of common carotid arterial IMT, common carotid arterial distensibility (CD),local pulse wave velocity(PWVβ) and stiffness(β) were calculated automatically.The correlations that the IMT, PWVβ and β were correlated positively with aging and CD was correlated negatively with between IMT and PWVβ or β, while no correlation between IMT and CD.The positive correlation was found correlation between IMT and age ( P＜0.05) ;In 30～39 and 40～49 years old groups,PWVβ increased and CD decreased with aging;In 50～59 years old group,PWVβ and β increased with aging;But in 60～69 years these parameters changed with aging in subjects＜60 years old.Conclusions RF-data technology could quantitativly evaluate common carotid arterial IMT and elasticity, the normal values of the related parameters were determined with aging,it may be a promising modality to assess the arterial condition.
