Non‐Contrast Assessment of Blood–Brain Barrier Permeability to Water: Improved Signal Modeling and Data Acquisition

Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 1998-2008, April 2026.
ABSTRACT Purpose Water‐extraction‐with‐phase‐contrast‐arterial‐spin‐tagging (WEPCAST) MRI is a non‐contrast method to estimate the blood–brain barrier (BBB) permeability to water. Similar to other arterial‐spin‐labeling (ASL) based techniques, signal‐to‐noise ratio is a limitation.

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 ...

Validation of Intravoxel Incoherent Motion MRI Using Perfused Explanted Human Livers

Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 2291-2304, April 2026.
ABSTRACT Purpose Evaluate the feasibility of using perfused explanted human livers for validating intravoxel incoherent motion (IVIM). Methods Eight (n = 8) explanted livers from deceased donors were obtained. The portal vein and hepatic artery of each explanted liver were connected to a perfusion system.

Pulmonary Transit Time Can Be Accurately Quantified From Non‐Arterial Input Function Series in First‐Pass Cardiac Perfusion MRI

Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 2207-2213, April 2026.
ABSTRACT Purpose Previous studies suggested that arterial‐input‐function (AIF) images are necessary to avoid signal saturation for pulmonary transit time (PTT) measurements. This study challenges that notion by investigating whether PTT can be accurately measured using blood pool signals from myocardial enhancement (non‐AIF) images during resting first‐

Feasibility Study for Dual Phase Free Breathing 3D bSSFP MRA With Preserved Eddy‐Current Tolerance With Adaptive k‐Space Lengths (PETAL) Acquisition

Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 2078-2091, April 2026.
ABSTRACT Purpose To demonstrate the feasibility of a novel dual‐phase self‐navigated, free‐breathing balanced steady‐state free‐precession whole‐heart MRA acquisition for aortic annulus size measurement using a Cartesian trajectory that mitigates eddy‐current artifacts by minimizing k‐space jumps between consecutive readouts with predictable scan times.

Deep Learning Reconstruction for 129Xe Diffusion‐Weighted MRI Enables Use of Natural Abundant Xenon and Improved Image Acceleration

Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 2214-2222, April 2026.
ABSTRACT Purpose (i) To assess whether 129Xe apparent diffusion coefficient (ADC) and diffusive length scale (LmD) metrics are quantitatively preserved with deep learning (DL) accelerated acquisition and reconstruction and (ii) to evaluate the feasibility of 129Xe diffusion weighted imaging with natural‐abundance xenon at increased acceleration factors.
