Motion‐Compensated Diffusion Imaging With Phase‐Contrast for Robust Quantification of Regional Cerebral Blood Flow

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 1, Page 238-246, July 2026.
ABSTRACT Purpose To develop and evaluate a motion‐compensated diffusion imaging with phase‐contrast (MC‐DIP) technique for mitigating errors in regional cerebral blood flow (rCBF) quantification caused by physiological brain motion. Methods Diffusion‐weighted images were acquired in 11 healthy volunteers on a 3.0 T MRI system using three gradient ...

A Numerical Alternative to MR Thermometry for Safety Validation of Multi‐Channel RF Transmit Coils

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 1, Page 469-484, July 2026.
ABSTRACT Purpose This study proposes a numerical technique to estimate peak local specific absorption rate (SAR) uncertainty of multi‐channel RF coils during the process of safety validation as an alternative to experimental temperature and electric‐field measurements, and demonstrates its use to enable human studies at 10.5 T.

Assessing Measurement Repeatability of a Novel Anisotropic Phantom for Advanced Diffusion MRI Models

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 1, Page 339-348, July 2026.
ABSTRACT Purpose Diffusion MRI is widely used to characterize tissue microstructure, but standardization remains challenging, particularly for advanced models or regions with crossing fibers. Phantoms provide controlled environments to assess measurement repeatability independent of biological variability.

Offline Reconstruction of Diffusion MRI Acquisitions for Comparison Between Complex PCA‐Based and AI‐Based Denoising

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 1, Page 435-447, July 2026.
ABSTRACT Purpose Optimal diffusion MRI (dMRI) data for image denoising is often unavailable from scanner reconstruction. In this work, we make available an offline reconstruction pipeline for GE dMRI acquisitions, giving access to complex dMRI data. Furthermore, we compare the efficacy of GE HealthCare's AIR‐Recon DL (ARDL), a proprietary convolutional

Double Asymmetric Spin Echo EPI (dASE‐EPI) Enables fMRI of the Entire Rat Brain at 9.4 T

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 1, Page 366-373, July 2026.
ABSTRACT Purpose Development and evaluation of a double asymmetric spin echo planar imaging (dASE‐EPI) sequence to balance sensitivity to blood oxygenation level‐dependent (BOLD) contrast with mitigation of susceptibility‐induced intravoxel spin dephasing in ultra high‐field rodent brain imaging.

Reducing Inhomogeneous MT (ihMT) Acquisition Time Using Frequency Alternation at Low Duty Cycle for Single Offset (FALSO) MT Preparations

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 1, Page 191-202, July 2026.
ABSTRACT Purpose To evaluate Frequency Alternation at Low duty cycle for Single Offset (FALSO) as a novel Magnetization Transfer (MT) preparation scheme to increase speed and/or spatial resolution of inhomogeneous MT (ihMT) MRI by reducing the number of volumes required.

Modeling of Fiber Orientation‐Dependent R1 Relaxation in Human White Matter In Vivo Within The Framework of The Transient Hydrogen Bond Model

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 1, Page 315-322, July 2026.
ABSTRACT Purpose Axon fiber orientation‐dependent R1 relaxation in human white matter (WM) in vivo at B0 = 1.5 T, 3 T, and 7 T was studied within the framework of the transient hydrogen bond (THB) model, which attributes MR signal relaxation to quantum magnetization interactions of water and motion‐restricted protons in hydrophilic heads of lipid ...
