Non‐Subtractive Arterial Spin Labeling‐Based (NSASL) Renal Magnetic Resonance Angiography (MRA): Development and Clinical Feasibility Evaluation

Journal of Magnetic Resonance Imaging, Volume 63, Issue 5, Page 1435-1447, May 2026.
ABSTRACT Background Non‐contrast renal MR angiography (MRA) is valuable for patients who cannot receive contrast agents or when avoiding radiation is desired. However, the conventional inflow inversion recovery (IFIR) method is limited by incomplete background suppression, venous contamination, and motion sensitivity.

Clinical Applications of Electrical Conductivity Imaging Using MRI

Journal of Magnetic Resonance Imaging, Volume 63, Issue 5, Page 1224-1245, May 2026.
ABSTRACT Magnetic resonance imaging (MRI) has emerged as a noninvasive technique for probing the electrical properties of biological tissues: electrical conductivity and relative permittivity. This review focuses on the electrical conductivity and provides a comprehensive overview of applications across both low‐ and high‐frequency regimes.

Migration rate, timing of sex, and resident genetic diversity jointly shape effective gene flow during rotifer colonization

Limnology and Oceanography, Volume 71, Issue 5, May 2026.
Abstract Dispersal is a complex process that affects all living organisms, with the settlement phase being particularly critical. This phase depends on the interaction between the environmental conditions of the new habitat and the biological traits of both resident and immigrant populations.

Temporal dynamics of mesopelagic fishes within a mesoscale eddy: A Lagrangian perspective

Limnology and Oceanography Letters, Volume 11, Issue 3, May 2026.
Abstract Mesoscale eddies are physically dynamic environments, yet biological responses within them are often treated as static, with eddy polarity (anticyclones vs. cyclones) serving as the dominant conceptual framework. Temporal dynamics of animals within eddies—particularly at mid‐trophic levels—remain largely unresolved.

A preclinical setup for spatially fractionated radiation therapy with electrons

Medical Physics, Volume 53, Issue 5, May 2026.
Abstract Background Spatially fractionated radiation therapy (SFRT) has therapeutic potential as a priming therapy which boosts tumor control. However, the optimal delivery and spatial fractionation parameters have not been deciphered and the mechanisms at play are not yet fully understood.

Velocity Spectrum Imaging Using Velocity Encoding Preparation Pulses

Magnetic Resonance in Medicine, Volume 95, Issue 5, Page 2568-2579, May 2026.
ABSTRACT Purpose The goal of this article is to introduce a technique to measure the velocity distribution of water inside each voxel of an MR image. The method is based on the use of motion sensitizing gradients with changing first moment to encode velocity. As such, it is completely non‐invasive and requires no contrast injections.

Highly Reproducible, Vendor‐Agnostic, Motion‐Insensitive Liver PDFF Mapping at 0.55T, 1.5T, and 3T

Magnetic Resonance in Medicine, Volume 95, Issue 5, Page 2797-2813, May 2026.
ABSTRACT Purpose To develop and validate a vendor‐agnostic, motion‐insensitive proton‐density fat‐fraction (PDFF) quantification method. Methods Flip‐angle‐modulated (FAM) 2D chemical‐shift‐encoded (CSE) MRI for PDFF quantification was implemented in both the vendor‐agnostic platform Pulseq (“Pulseq‐FAM”) and one vendor‐specific platform (“GE‐specific ...

Pole‐To‐Pole 3D Radial Trajectory Designs Improve Image Quality and Quantitative Parametric Mapping in the Brain and Heart

Magnetic Resonance in Medicine, Volume 95, Issue 5, Page 2627-2643, May 2026.
ABSTRACT Purpose To design 3D radial spiral phyllotaxis trajectories aimed at removing phase inconsistencies, improving image quality, and enhancing parametric mapping accuracy by acquiring nearly opposing spokes starting from both hemispheres in 3D radial k‐space. Methods Two 3D radial trajectories, pole‐to‐pole and continuous spiral phyllotaxis, were
