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 ...

Free‐Breathing Multi‐Slice Co‐Registered Cardiac T1, T2, and ADC Mapping With Spin‐Echo Echo Planar Imaging

Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 2035-2051, April 2026.
ABSTRACT Purpose To develop a free‐breathing method for multi‐slice co‐registered cardiac T1, T2, and ADC maps using single‐shot spin‐echo echo planar imaging (SE‐EPI). Methods T1, T2, and diffusion weighted images in five slices were acquired with SE‐EPI readouts during free breathing using interleaved acquisition of slices, non‐selective inversion ...

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.

Angiotensin‐(1–7) Alleviates Isoproterenol‐Induced Cardiac Hypertrophy by Suppressing Autophagy and Apoptosis Through the Synergistic Action of Mas Receptor and Angiotensin II Type 2 Receptor

Acta Physiologica, Volume 242, Issue 4, April 2026.
ABSTRACT Aim The aim of this study is to determine whether Angiotensin‐(1–7) [Ang‐(1–7)] alleviates isoproterenol (ISO)–induced cardiac hypertrophy by suppressing excessive autophagy and apoptosis through coordinated Mas receptor (MasR) and angiotensin II type‐2 receptor (AT2R) signaling, and to elucidate the underlying mechanisms.
