Age related high pulsatility of distal brain arteries is
thought to damage exposed brain tissue, leading to brain
atrophy and cognitive decline among elderly. Previous
studies have focused on assessing central pulsatility or
pulsatility in cervical arteries feeding the brain. We
show that high-resolution 4D Flow MRI is capable of
assessing pulsatility of distal branches of the cerebral
arterial circulation, a result that should stimulate
research aimed for understanding arterial pulsatility as
a contributing factor to dementia.
