Simultaneous Assessment of Skeletal Muscle Energetics and Blood Flow During Dynamic Exercise by Interleaved 31P‐MRS/1H‐MRI

Magnetic Resonance in Medicine, Volume 96, Issue 1, Page 13-26, July 2026.
ABSTRACT Purpose To simultaneously measure skeletal muscle energetics and blood flow (BF) before, during, and after dynamic plantar flexion exercise (PFE). Methods Non‐localized pulse‐acquire phosphorus‐31 magnetic resonance spectroscopy (31P MRS) and phase contrast flow magnetic resonance imaging (1H MRI) using golden‐angle rotated spiral readouts ...

SELFIE: Self‐Supervised Learning for Fast Dynamic Golden‐Angle Radial MRI

NMR in Biomedicine, Volume 39, Issue 7, July 2026.
SELFIE enables reference‐free reconstruction for dynamic golden‐angle radial MRI. The self‐supervised training is enabled by leveraging the flexible temporal resolution of golden‐angle sampling to create self‐references and temporal sparsity. Evaluated on accelerated DCE‐MRI in patients with gynecological cancer and motion‐resolved free‐breathing ...

Non‐invasive pressure–volume loop analysis in left ventricular load manipulation

Clinical Physiology and Functional Imaging, Volume 46, Issue 4, July 2026.
Abstract Background Clinical monitoring of patients with heart failure or cardiomyopathy is facilitated by detailed assessment of cardiac loading conditions. Specifically, alterations in preload and afterload may unmask pathology through effects on ventricular pressure–volume (PV) relations. Therefore, the aim was to assess non‐invasive PV loops during

Unveiling sex dimorphism in the healthy cardiac anatomy: Fundamental differences between male and female heart shapes

The Journal of Physiology, Volume 604, Issue 13, Page 5512-5534, 1 July 2026.
Abstract figure legend We present a shape modelling‐based morphological analysis of sex differences in cardiac anatomy. We conduct our analysis on 456 healthy subjects from the UK Biobank (227M/229F) to uncover sex‐based differences in healthy cardiac morphology.

In silico predictions of action potential propagation in doxorubicin cardiotoxicity: A parametric study using preclinical 3D magnetic resonance imaging‐based fibrotic left ventricle models

The Journal of Physiology, Volume 604, Issue 13, Page 5585-5609, 1 July 2026.
Abstract figure legend Schematic overview of the study's methodology and key findings. In a preclinical swine model, doxorubicin administration induced cardiotoxicity, characterized by diffuse fibrotic remodelling and altered electrical function, as assessed by magnetic resonance (MR) imaging and electrophysiological mapping.
