Simultaneous Acquisition of Magnetic Resonance Elastography (MRE) and Diffusion Tensor Imaging (DTI) Optimized for Human Brain

Magnetic Resonance in Medicine, Volume 96, Issue 3, Page 1111-1120, September 2026.
ABSTRACT Purpose Increase clinical acceptance of MRE and DTI by shortening the scan time by half and providing diffusive and mechanical property maps that are inherently co‐registered. This proof‐of‐concept study evaluates the simultaneous DTI‐MRE acquisition in the human brain and compares its results to conventional DTI and MRE measurements.

Uncertainty Quantification for Cardiac Diffusion Tensor Imaging Without Additional Datasets

Magnetic Resonance in Medicine, Volume 96, Issue 3, Page 1458-1463, September 2026.
ABSTRACT Purpose Cardiac diffusion tensor imaging (cDTI) is subject to physiological noise, thermal noise, and signal corruption, which cause errors in diffusion measures. While a larger dataset can be decimated to investigate the general precision of measures from fitting smaller datasets, uncertainty quantification (UQ) methods for fitting entire ...

Evaluating the Influence of Injury‐Induced Microstructural Variations on the Efficacy of a Diffusion MRI‐Derived Axon Diameter Surrogate

Magnetic Resonance in Medicine, Volume 96, Issue 3, Page 1355-1364, September 2026.
ABSTRACT Purpose To investigate the utility of a recently demonstrated diffusion MRI derived axon diameter surrogate measure (∆D⟂) under pathologic conditions induced by a spinal cord injury model. Methods Contusion injuries were performed on the thoracic–lumbar spinal cord of adult male rats.

Four Directions, One Solution: Enabling Rapid Diffusion Tensor MRI for Ultra‐Low Field Using Deep Learning

Magnetic Resonance in Medicine, Volume 96, Issue 3, Page 1413-1426, September 2026.
ABSTRACT Purpose This study revisits the tetrahedral encoding strategy originally proposed to accelerate Diffusion Tensor Magnetic Resonance Imaging (DT‐MRI) by reducing the requisite number of diffusion‐weighted measurements to four. We examine its practical limitations and explore how artificial intelligence (AI) can extend its utility. Specifically,

Collisionless Shocks: Contemporary State After Three Quarters of a Century of Research

Reviews of Geophysics, Volume 64, Issue 3, September 2026.
Abstract The collisionless shock research started in the late 1950s. Since then, plenty of data have been accumulated due to the large number of missions in the heliosphere, providing in situ measurements of the fields and particles. The quality of these measurements has vastly improved, especially in the last two decades.
