Lower cerebral blood flow but not cerebrovascular response in elastin haploinsufficient mice

open access: yesExperimental Physiology, EarlyView.
Abstract Elastin insufficiency is associated with structural differences in the large elastic arteries and cerebral artery dysfunction. However, previous studies have not assessed potential sex differences in cerebrovascular function. We measured cerebral blood flow (CBF) using arterial spin labeling MRI at rest and in response to hypercapnia challenge

Coupling between global brain blood oxygen level‐dependent activity and cerebrospinal fluid dynamics in young endurance athletes

open access: yesExperimental Physiology, EarlyView.
Abstract Cerebrospinal fluid (CSF) contributes to brain waste clearance through its coupling with cerebral haemodynamics. Aerobic exercise promotes brain health, but its influence on brain waste clearance remains unclear. This study examined the coupling between CSF and cerebral haemodynamics in endurance athletes. Fifteen young male endurance athletes

The effects of a (poly)phenol‐rich food intervention on markers of exercise‐induced inflammation and oxidative stress: A randomised controlled trial

open access: yesExperimental Physiology, EarlyView.
Abstract This study examined whether consuming a (poly)phenol‐rich food before strenuous muscle‐damaging exercise can modify post‐exercise markers of inflammation and oxidative stress. Using a double‐blinded, randomised, placebo‐controlled, between‐subjects design, 26 recreationally active males (n = 15) and females (n = 11) consumed higher‐(poly ...

Simultaneous Cerebral Blood Flow and Cerebrovascular Reactivity Obtained From Novel Multi‐Band Multi‐Echo Pseudo‐Continuous Arterial Spin Labeling (M2‐PCASL) Sequence: A Test–Retest Reliability Study

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 1, Page 37-48, July 2026.
ABSTRACT Purpose We aim to assess the reliability of cerebral blood flow (CBF) and cerebrovascular reactivity (CVR) obtained simultaneously from a novel multi‐band pseudo‐continuous arterial spin labeling (M2‐PCASL) sequence and hypercapnic gas challenge, to examine factors influencing CBF variability, and to evaluate the impact of carbon dioxide (CO2)

Clinically Feasible White Matter Fiber Tractography in Peritumoral Zones With Cerebral Vasogenic Edema

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 1, Page 287-301, July 2026.
ABSTRACT Purpose In diffusion MRI, vasogenic edema manifests as a major fraction of isotropic water that dilutes the anisotropic intra‐axonal portion of the signal. Many tractography algorithms mistake vasogenic edema for the white matter boundary and terminate tracking to prevent producing spurious streamlines.

Modelling Motion‐Induced Signal Corruption in Steady‐State Diffusion MRI

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 1, Page 66-82, July 2026.
ABSTRACT Purpose Diffusion‐weighted steady‐state free precession (DW‐SSFP) is a diffusion imaging sequence achieving high SNR efficiency. A key challenge for in vivo DW‐SSFP is the sequence's severe motion sensitivity, currently limiting investigations to low or no motion regimes.
