Free‐Breathing Magnetization Transfer Imaging of the Lung at 0.55 T Using bSTAR

Magnetic Resonance in Medicine, Volume 96, Issue 1, Page 203-213, July 2026.
ABSTRACT Purpose To develop a clinically applicable method for magnetization transfer (MT) imaging of the lung at 0.55 T. Methods MT imaging of the chest was explored in healthy volunteers at 0.55 T using a self‐gated 3D half‐radial dual‐echo balanced steady‐state free precession sequence (bSTAR), a 2D multi‐slice gradient echo method (GRE) acquired in

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.

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 ...

Using Platt\u27s scaling for calibration after undersampling -- limitations and how to address them

When modelling data where the response is dichotomous and highly imbalanced, response-based sampling where a subset of the majority class is retained (i.e., undersampling) is often used to create more balanced training datasets prior to modelling ...
