Motion Mitigation Techniques for Abdominal and Cardiac MR Imaging

Journal of Magnetic Resonance Imaging, Volume 63, Issue 4, Page 917-937, April 2026.
ABSTRACT MRI of the heart and abdominal organs provides unparalleled soft tissue contrast and quantitative biomarkers, yet remains highly susceptible to physiological motion. Contractions of the myocardium, respiratory excursions, peristalsis, vascular pulsatility, and unpredictable bulk patient movement generate artifacts that impair image quality ...

What If Each Voxel Were Measured With a Different Diffusion Protocol?

Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 2277-2290, April 2026.
ABSTRACT Purpose Expansion of diffusion MRI (dMRI) both into the realm of strong gradients and into accessible imaging with portable low‐field devices brings about the challenge of gradient nonlinearities. Spatial variations of the diffusion gradients make diffusion weightings and directions non‐uniform across the field of view, and deform perfect ...

Multiparametric MRI to Predict Response to Irreversible Electroporation Plus Anti‐PD‐1 Immunotherapy in Pancreatic Ductal Adenocarcinoma

Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 2266-2276, April 2026.
ABSTRACT Purpose To investigate contrast‐enhanced T1‐weighted MRI and diffusion‐weighted magnetic resonance imaging (DWI) for early prediction of tumor response to combined irreversible electroporation (IRE) and anti‐PD‐1 immunotherapy. Methods Murine pancreatic ductal adenocarcinoma (PDAC) cells KRAS* were inoculated into the pancreas of C57BL/6 mice.

The Effect of Voxel Volume and Voxel Shape on Cardiac Diffusion Tensor Imaging Metrics

Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 2063-2077, April 2026.
ABSTRACT Purpose Cardiac diffusion tensor imaging (cDTI) is signal‐to‐noise ratio (SNR)‐limited due to diffusion signal attenuation, long echo times from gradient moment nulling, and moderate myocardial T 2$$ {}_2 $$. Increasing voxel volume improves SNR but reduces spatial sensitivity and introduces physiological bias.

Quantitative Susceptibility Mapping in Skull Base Chordoma: In Silico Analysis and In Vivo Application Towards Indirect Hypoxia Assessment

Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 2092-2105, April 2026.
ABSTRACT Purpose To evaluate quantitative susceptibility mapping (QSM) beyond the brain through realistic simulations and to explore preliminary evidence that may be indicative of hypoxia in skull base chordomas (SBC). Methods Each step of the QSM pipeline was optimized within an in silico framework consisting of (i) phase unwrapping, (ii) background ...
