Electrophysiological characterization of pre‐adolescents born with intrauterine growth restriction: insights from clinical and computational data

The Journal of Physiology, EarlyView.
Abstract figure legend Depolarization and repolarization duration analysis was conducted in preadolescent groups with IUGR and controls using a 12‐lead ECG. Principal component analysis was applied over the 12‐lead ECGs to generate spatially transformed leads better suited for robust ECG fiducial points detection.

Fetal glucose availability: a key regulator of the metabolic, hormonal and contractility profiles of the fetal sheep heart

The Journal of Physiology, EarlyView.
Abstract figure legend To investigate the role of glucose availability in fetal left ventricle (LV) development, this study assessed whether maternal late gestation undernutrition (LGUN; 50% of Control diet) induced alterations in the contractility, metabolic, and hormonal profile can be ameliorated in LGUN fetuses receiving glucose infusion (LGUN+G ...

A constitutive modelling framework for applications to in vivo longitudinal data: Evaluation in a 60‐day head‐down bed rest study on arterial function

The Journal of Physiology, EarlyView.
Abstract figure legend We proposed a computational constitutive modelling framework that leverages longitudinal acquisitions of haemodynamic waveforms at multiple arterial locations to achieve a biomechanical characterisation of their (micro)structural remodelling processes.

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

Magnetic 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.

Sex differences in cerebral pulsatility and damping: A 4D flow MRI study

Experimental Physiology
Cerebral pulsatility is a potential marker of cerebrovascular health, yet little is understood about sex differences in cerebral pulsatility with age, especially within different cerebral arteries.

Respiration Can Trigger Cerebrovascular Reactivity: A Novel Method to Quantify Cerebrovascular Resistance Dynamics Using Real‐Time Phase‐Contrast MRI

Magnetic Resonance in Medicine, Volume 96, Issue 1, Page 83-95, July 2026.
ABSTRACT Purpose To directly quantify respiration‐driven cerebrovascular resistance dynamics (CRD) using a gas‐free MRI framework based on the internal‐to‐external artery carotid flow ratio (ratio_Q). Theory and Methods Two independent datasets (n = 10 and n = 17) were used to evaluate repeatability and to compare breathing conditions.

Motion‐Compensated Diffusion Imaging With Phase‐Contrast for Robust Quantification of Regional Cerebral Blood Flow

Magnetic Resonance in Medicine, Volume 96, Issue 1, Page 238-246, July 2026.
ABSTRACT Purpose To develop and evaluate a motion‐compensated diffusion imaging with phase‐contrast (MC‐DIP) technique for mitigating errors in regional cerebral blood flow (rCBF) quantification caused by physiological brain motion. Methods Diffusion‐weighted images were acquired in 11 healthy volunteers on a 3.0 T MRI system using three gradient ...

Rapid Tissue‐CSF Water Exchange in the Human Brain Revealed by Magnetization Transfer Indirect Spin Labeling

Magnetic Resonance in Medicine, Volume 95, Issue 6, Page 3270-3283, June 2026.
ABSTRACT Purpose To apply the Magnetization Transfer Indirect Spin Labeling (MISL) MRI technique for quantifying tissue‐CSF water exchange in the human brain, and to investigate its utility in (1) evaluating tissue‐CSF water exchange within perivascular spaces (PVS), and (2) characterizing altered water exchange dynamics in pathologic conditions ...
