Whole‐Brain Diffusion MRI at 7T With Universal Multiband GRAPE pTx Pulses

Magnetic Resonance in Medicine, EarlyView.
Purpose To improve signal strength and homogeneity of whole‐brain diffusion‐weighted imaging (DWI) at 7T. Methods Universal multiband excitation and refocusing pulses were optimized with the gradient ascent pulse engineering (GRAPE) algorithm across a database of B1+$$ {B}_1^{+} $$ and B0$$ {B}_0 $$ maps obtained from 20 subjects.

Contrast‐Induced Encephalopathy Following Elective Endovascular Aneurysm Treatment: The Role of Dual‐Energy CT and Correlation With Delphi Diagnostic Criteria

Journal of Medical Imaging and Radiation Oncology, EarlyView.
ABSTRACT Introduction Contrast‐induced encephalopathy (CIE) is an increasingly recognised neurological complication of iodinated contrast administration during neurointerventional procedures. Recently published 2025 Delphi‐based diagnostic criteria and management algorithms aim to standardise clinical practice; however, optimal neuroimaging strategies ...

T2 mapping outperforms normalised FLAIR in identifying hippocampal sclerosis [PDF]

, 2015
Rationale Qualitatively, FLAIR MR imaging is sensitive to the detection of hippocampal sclerosis (HS). Quantitative analysis of T2 maps provides a useful objective measure and increased sensitivity over visual inspection of T2-weighted scans. We aimed to

Gliomas with pleomorphic and pseudopapillary features (GPAP) are circumscribed tumors with targetable mutations, prolonged survival, and frequent tumor predisposition

Brain Pathology, EarlyView.
DNA methylation profiling identifies GPAP as a distinct circumscribed glioma with a characteristic expansive, multicystic radiological appearance, pleomorphic and pseudopapillary histology, a recognizable CNV profile, druggable molecular alterations, and recurrent cancer predisposition syndromes.

The reliability and interobserver reproducibility of T2/FLAIR mismatch in the diagnosis of IDH-mutant astrocytomas [PDF]

, 2021
PURPOSE:The reliability and reproducibility of T2-weighted imaging/ fluid-attenuated inversion recovery (T2/FLAIR) mismatch were investigated in the diagnosis of isocitrate dehydrogenase (IDH) mutant astrocytoma between WHO grade II and III diffuse ...

Recognizing Signs of Abusive Head Trauma

Journal of Paediatrics and Child Health, EarlyView.
ABSTRACT Background Abusive head trauma (AHT) remains the leading cause of fatal traumatic brain injury in infants and young children. Diagnosis is frequently delayed or missed due to nonspecific clinical presentation and unreliable histories, making neuroimaging a critical component of the diagnostic process. Objective This review synthesises computed

Accelerating Stroke MRI With Diffusion Probabilistic Models Through Large‐Scale Pre‐Training and Target‐Specific Fine‐Tuning

Magnetic Resonance in Medicine, Volume 96, Issue 5, Page 2396-2411, November 2026.
ABSTRACT Purpose To develop a data‐efficient strategy for accelerated MRI reconstruction with Diffusion Probabilistic Generative Models (DPMs) that enables faster scan times in clinical stroke MRI when only limited fully‐sampled data are available. Methods Our simple training strategy first pre‐trains a DPM on a large, diverse collection of publicly ...
