DOI: 10.1038/s41598-025-28405-8
Abstract: A single, arterial-optimized 4D-flow MRI acquisition may enable fast assessment of both cerebral arterial and venous flow. However, arteries and veins require different velocity encoding (VENC) settings for optimal velocity-to-noise ratio (VNR). Consequently, venous measurements… read more here.

DOI: 10.1053/j.jvca.2017.11.030
Abstract: OBJECTIVE Venous congestion is a possible mechanism leading to acute kidney injury (AKI) following cardiac surgery. Portal vein flow pulsatility is an echographic marker of cardiogenic portal hypertension and might identify clinically significant organ congestion.… read more here.

DOI: 10.1152/physiol.2025.40.s1.1801
Abstract: Background: High large central artery (aorta, carotids) stiffness is purported to cause microvasculature remodeling and damage to high flow, low resistance organs as a result of increased transmission of excessive pressure and flow pulsatility into… read more here.
