Quantitative pulsatility measurements using 3D Dynamic Ultrasound Localization Microscopy
Chloé Bourquin, Jonathan Porée, Brice Rauby +11
A rise in blood flow velocity variations (i.e., pulsatility) in the brain, caused by the stiffening of upstream arteries, is associated with cognitive impairment and neurodegenerat…
