Longer action potential duration in the Purkinje network than in the ventricular myocardium delays retrograde activation of the human His‐Purkinje system

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Activation time (AT) maps from right ventricular apical pacing in a human ventricles model with longer action potential duration in the His‐Purkinje system (HPS) than in the myocardium (MYO). For pacing with a long S1S2 coupling interval (CI), the AT from the myocardial pacing site to the first AT of the HPS (ATMYO) is longer ...

Spatial and temporal scales in plant phenotyping for crop water stress assessment: A review

open access: yesThe Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract Water stress is a major limiting factor for crop productivity worldwide, and its impacts are intensifying due to climate variability and increasing water scarcity. This review focuses on the spatial and temporal scales in plant phenotyping as a critical approach to improving crop water‐stress assessment and supporting precision water ...

Simultaneous Multi‐Slice Acceleration for Free‐Breathing Motion Corrected Late Gadolinium Enhancement Imaging

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 6, Page 3333-3340, June 2026.
ABSTRACT Purpose The objective of this study was to develop and evaluate an accelerated free‐breathing motion corrected and averaged late gadolinium enhancement MRI (FB PSIR‐MoCo LGE) protocols. Methods Simultaneous multi‐slice (SMS) bSSFP imaging with GC‐LOLA correction and a multiband factor of two was implemented into a FB PSIR‐MoCo LGE sequence ...

Impact of Partial Echo on 4D Flow MRI: The Insight From Synthetic MRI

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 6, Page 3462-3475, June 2026.
ABSTRACT Purpose The aim of this study is to investigate the impact of the partial echo on 4D flow MRI sequences thanks to in silico coupled MRI‐CFD (computational fluid dynamics) simulations. Methods Two sequences are studied: one with a full echo (FE) and another using partial echo (PE) with an echo symmetry fraction of 0.75.

Modeling the Intermediate Flow Regime in Flow‐Compensated Intravoxel Incoherent Motion MRI

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 6, Page 3476-3487, June 2026.
ABSTRACT Purpose The intravoxel incoherent motion (IVIM) model is commonly used to separate the effects of motion related to diffusion and blood microcirculation (perfusion) on the MR signal. Depending on the encoding time (T), it is possible to probe the different temporal regimes of blood motion, which resemble a ballistic flow at short T and a ...

Toward Super‐Resolution Reconstruction of Diffusion–Relaxation MRI Using Slice Excitation With Random Overlap (SERO)

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 6, Page 3213-3226, June 2026.
ABSTRACT Purpose Diffusion MRI probes tissue microstructure, but low SNR and limited resolution hinder detection of features and parameter estimates. We introduce slice excitation with random overlap (SERO), which enables variable repetition times (TRs) and diffusion weighting within a single shot.
