Dynamic contrast enhanced‐magnetic resonance fingerprinting (DCE‐MRF): A new quantitative MRI method to reliably assess tumor vascular perfusion

Magnetic Resonance in Medicine, Volume 94, Issue 6, Page 2578-2592, December 2025.
Abstract Purpose The clinical utility of conventional DCE‐MRI methods is limited by the use of conventional qualitative dynamic T1‐weighted images, resulting in poor reproducibility. This study presents the initial implementation of a new DCE‐magnetic resonance fingerprinting (DCE‐MRF) methodology to provide reproducible, quantitative assessments of ...

Comparison of Low‐Rank Denoising Methods for Dynamic Deuterium MRSI at 7 T

NMR in Biomedicine, Volume 38, Issue 10, October 2025.
Six low‐rank denoising methods for dynamic 2H‐MRSI were compared using simulated and in vivo data: Global PS, Local PS, Stacked PS, SPIN‐SVD, GL‐HOSVD and tMPPCA. SPIN‐SVD performed best in simulations, while SPIN‐SVD, GL‐HOSVD and tMPPCA performed well in vivo. GL‐HOSVD and tMPPCA performed similarly, with tMPPCA preferred for computational efficiency.

Geometric modeling of phase ordering for the isotropic–smectic A phase transition

Frontiers in Soft Matter
BackgroundLiquid crystal (LC) mesophases have an orientational and positional order that can be found in both synthetic and biological materials. These orders are maintained until some parameter, mainly the temperature or concentration, is changed ...

High‐resolution, volumetric diffusion‐weighted MR spectroscopic imaging of the brain

Magnetic Resonance in Medicine, Volume 94, Issue 2, Page 450-469, August 2025.
ABSTRACT Purpose To achieve high‐resolution, three‐dimensional (3D) quantitative diffusion‐weighted MR spectroscopic imaging (DW‐MRSI) for molecule‐specific microstructural imaging of the brain. Methods We introduced and integrated several innovative acquisition and processing strategies for DW‐MRSI: (a) a new double‐spin‐echo sequence combining ...

Assessment of the Nutraceutical Properties of Wild Strawberry (Fragaria vesca L.) Extracts on Human Colorectal Cell Lines

Molecular Nutrition &Food Research, Volume 69, Issue 11, June 2025.
The study explores the nutraceutical potential of wild strawberry (Fragaria vesca L.) by assessing its effects on multiple colorectal carcinoma cell lines. Wild strawberry phytochemicals were able to reduce SW480 cell viability by inducing cell cycle arrest and by promoting programmed cell death in E705 cells, with no toxicity on healthy colorectal ...
