p‐Brain: A Modular Open‐Source Framework for Automated Quantitative DCE‐MRI of Cerebral Perfusion, Microvasculature, and Blood–Brain Barrier Permeability

Magnetic Resonance in Medicine, Volume 96, Issue 6, Page 2601-2614, December 2026.
ABSTRACT We present p‐Brain, a modular, open‐source framework for reproducible, automated quantitative DCE‐MRI at scale. Rather than a fixed pipeline, p‐Brain is built from interchangeable stages (ingestion, T1/M0$$ {T}_1/{M}_0 $$ fitting, vascular and tissue ROI extraction, signal‐to‐concentration conversion, kinetic modeling, and quality control ...

Prenatal Diagnosis of Recurrent Fetal Intracranial Hemorrhage and a Maternally Inherited COL4A1 Variant of Uncertain Significance: A Case Report With Maternal Reverse Phenotyping

Clinical Case Reports, Volume 14, Issue 11, November 2026.
ABSTRACT A 33‐year‐old woman with two consecutive pregnancies affected by fetal left periventricular germinal matrix hemorrhage (Grade IV) and progressive ventriculomegaly underwent trio whole‐exome sequencing. A heterozygous COL4A1 c.4249G>C (p.Gly1417Arg) variant, classified as a variant of uncertain significance, was identified in the fetus of the ...

Mental Scene and Memory Construction and the Hippocampus

Hippocampus, Volume 36, Issue 6, November 2026.
ABSTRACT A neurocomputational theory of scene and memory construction during memory recall, prospective thinking, and autobiographical memory is described. The theory describes the nature of the representation of scenes using spatial view cells in a continuous attractor network in the medial parahippocampal cortex, and how the location in the scene ...

Intratumoral and Peritumoral Functional Connectivity Reveals Network‐Level Signatures of Glioma

MedComm, Volume 7, Issue 11, November 2026.
Using resting‐state fMRI in 306 glioma patients, this study maps individualized intra‐ and peritumoral functional networks. Novel metrics (RIFR, RPTR) quantify tumor‐related network remodeling, correlating with pathology, structure, cognition, and survival. A prognostic model incorporating these network features achieves an AUC of 0.90.

Regularized Joint Reconstruction and Slab Combination for Accelerated Three‐Dimensional Multi‐Slab Diffusion‐Weighted Imaging Using Multi‐Scale Energy Models

Magnetic Resonance in Medicine, Volume 96, Issue 5, Page 2321-2335, November 2026.
ABSTRACT Purpose To jointly reconstruct high‐resolution diffusion‐weighted volumes and eliminate slab‐boundary artifacts while preserving fine anatomical detail from undersampled 3D multi‐slab k‐space acquisitions. Methods A bilinear forward model was formulated to describe the 3D multi‐slab acquisition, treating the image volume and slab excitation ...

Major Depressive Disorder With Non‐Suicidal Self‐Injury in Adolescents: Altered Morphological Inverse Divergence Gradient in Brain Structure and Gene Expression Patterns

Human Brain Mapping, Volume 47, Issue 15, October 15, 2026.
Using the morphometric inverse divergence gradient network (MIND‐Gd), this study shows that adolescents with major depressive disorder (MDD) and non‐suicidal self‐injury (NSSI) exhibit altered principal structural gradients relative to adolescents with MDD without NSSI, and that these gradient changes are spatially coupled to neurotransmitter receptor ...

Real-time tractography: computation and visualization

Brain Structure and Function
Did you know that even though tractography is often considered a computationally expensive and offline process, the latest algorithms can now be performed in real-time without sacrificing accuracy? Interactive real-time tractography has proven to be valuable in surgical planning and has the potential to enhance neuromodulation therapies, highlighting ...

White matter integrity assessed by diffusion tensor tractography in a patient with a large tumour mass but minimal clinical and neuropsychological deficits [PDF]

, 2012
Diffusion tensor imaging (DTI) tractography and image registration were used to investigate a patient with a massive left-sided brain tumor, whose size was largely disproportionate to his subtle neurological deficits.
