Abstract
Carotid arteries were examined by Duplex sonography in 116 healthy volunteers of between 16 and 78 years of age. We measured the internal carotid artery and common carotid artery peak systolic velocities and their ratio, the common carotid artery time-averaged velocity, the maximal diameter of the common carotid artery, and the common carotid artery volume flow (ml/min). Flow velocities and volume flow showed an age-dependent decrease.
