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.

Bright Ferritin for Non‐Invasive MRI Monitoring of the Fate of Transplanted hPSC‐Cardiomyocytes in the Infarcted Rat Heart

Magnetic Resonance in Medicine, Volume 96, Issue 1, Page 323-338, July 2026.
ABSTRACT Purpose To demonstrate that a recently reported bright ferritin magnetic resonance imaging (MRI) platform can track transplanted human pluripotent stem cell (hPSC)‐derived cardiomyocytes (hPSC‐CMs) longitudinally and on‐demand in the rat heart.

FlowVN Trained on a Single Dataset Enables Rapid Reconstruction of Highly Accelerated 4D Flow MRI Across Multiple Sites

Magnetic Resonance in Medicine, Volume 96, Issue 1, Page 374-386, July 2026.
ABSTRACT Purpose The aim of this study is to evaluate a deep variational network, FlowVN, for the reconstruction of heavily undersampled 4D Flow MRI across multiple sites. Methods FlowVN was trained on fully sampled 4D Flow MRI datasets of healthy volunteers from one site. The model was tested on retrospective undersampled data (R = 6–22) of six normal

Optimized Detection of Left Ventricular Hyperpolarized [1‐13C]Pyruvate Signal in Human Cardiac Metabolic Imaging

Magnetic Resonance in Medicine, Volume 96, Issue 1, Page 420-434, July 2026.
ABSTRACT Purpose This study aimed to improve the analysis of the left ventricular (LV) blood pool hyperpolarized [1‐13C]pyruvate signal for a more reliable quantification of downstream metabolic outcome. Methods Hyperpolarized [1‐13C]pyruvate magnetic resonance spectroscopic images were acquired dynamically at 3 Tesla in 106 participants (NCT03685175).

Improved Myocardial Sodium Quantification at 7 T Using Interleaved 23Na/1H pTx MRI With Motion and Anatomy‐Based B1 Correction

Magnetic Resonance in Medicine, Volume 96, Issue 1, Page 173-190, July 2026.
ABSTRACT Purpose To improve accuracy and repeatability of myocardial 23Na quantification in cardiac MRI at 7 T by combining retrospective respiratory and cardiac motion correction with a novel anatomy‐based B1 bias field correction. Methods In this study, a dual‐nuclear interleaved 23Na/1H MRI sequence at 7 T was applied.
