Abstract: Purpose To evaluate the correlation between carotid elasticity and age using electrocardiogram (ECG)-gated multi-detector CT angiography (MDCTA).Materials and Methods ECG-gated multiple phases MDCTA was performed on 34 vascular health subjects. Cross-section of the internal carotid artery (ICA), carotid bulb (CB) and common carotid artery (CCA) were measured at different phases. Carotid elasticity at ICA (EICA), CB (ECB) and CCA (ECCA) was calculated based on the carotid cross-sectional area changes and pulse pressure (PP).Results The EICA, ECB and ECCA showed significantly negative linear correlation with age (r=-0.73,-0.74 and-0.64,P<0.01). Conclusion The ECG-gated MDCTA is a novel method to evaluate carotid elasticity quantitatively and reliably. Carotid elasticity decreases with aging in vascular health population.
