The bony carotid canal
constrains the distensibility of the internal carotid artery, yielding locally
increased velocity pulsatility. Velocity pulsatility is significantly higher in
men compared to women and increases with ageing.
Table 2: Schematic overview of hemodynamic parameters
and velocity pulsatility index, area pulsatility index and flow pulsatility
index for every vessel per segment. (As flow = velocity*area, we focused separately on
the velocity- and area pulsatility.)
