Multimodal MRI and multiomics reveal high‐risk neurophenotype in brain‐gut circuits as therapeutic target for Crohn's disease

Interdisciplinary Medicine, Volume 4, Issue 4, July 2026.
Through a translational framework combining prospective dual‐center clinical cohorts with dextran sulfate sodium‐induced colitis models, this work integrated advanced neuroimaging, multi‐omics and neuromodulation interventions to redefine the high‐risk neurophenotype as a sustained pathogenic driver rather than a mere phenomenon, proposing brain‐gut ...

Characterizing the Diffusion Properties of Prostate Tissue Using Paired MR Microscopy and Multidimensional Diffusion MRI

Magnetic Resonance in Medicine, Volume 96, Issue 1, Page 349-365, July 2026.
ABSTRACT Purpose To characterize the diffusion properties of prostate epithelium and stroma in benign tissue and cancer. Methods Paired MR microscopy (20 μm) and multidimensional diffusion MRI (dMRI) (160 μm, b = 1000–2000 s/mm2, ∆ = 15–120 ms) were performed at 16.4 T on 17 fixed prostate tissue samples (14× benign, 2× Gleason 3 + 3, 1× Gleason 4 + 4).

The Role of Dendritic Spines in Water Exchange Measurements With Diffusion MRI: Double Diffusion Encoding and Free‐Waveform MRI

NMR in Biomedicine, Volume 39, Issue 7, July 2026.
Geometric water exchange in dendritic spines imparts a similar signature on diffusion‐MRI signals as permeative, transmembrane water exchange. Current diffusion MRI methods are non‐specific to geometric and permeative exchange. This work proposes a method to disentangle these two modes of exchange, yielding both more accurate estimates of permeative ...
