Deep learning-based classification of diffusion-weighted imaging-fluid-attenuated inversion recovery mismatch

Scientific Reports
The presence of a diffusion-weighted imaging (DWI)–fluid-attenuated inversion recovery (FLAIR) mismatch holds potential value in identifying candidates for recanalization treatment.

Ischemic stroke with unknown onset of symptoms: current scenario and perspectives for the future

Arquivos de Neuro-Psiquiatria, 2022
Background Stroke is a major cause of disability worldwide and a neurological emergency. Intravenous thrombolysis and mechanical thrombectomy are effective in the reperfusion of the parenchyma in distress, but the impossibility to determine the exact ...

From Fiber Bundles to Architected Membranes: Triply Periodic Minimal Surface Architectures for Biohybrid Artificial Lungs

Advanced Materials, Volume 38, Issue 55, 1 October 2026.
Additively manufactured triply periodic minimal surface (TPMS) membranes offer an architecture‐driven alternative to hollow fiber bundles in artificial lungs. Multiphysics simulations and endothelialized prototypes show that the 3D‐printable membrane architecture improves gas exchange, blood flow distribution, and hemocompatibility, enabling ...

The prominent hypointense vessel sign on susceptibility-weighted imaging (SWI) as a potential imaging biomarker for poor clinical outcome in acute ischemic stroke (AIS)

Radiology Case Reports, 2022
Susceptibility-weighted imaging (SWI) is a relatively new magnetic resonance imaging (MRI) technique used in the workup and diagnosis of brain pathologies. In the context of acute ischemic stroke (AIS), it is increasingly becoming useful in the diagnosis,

Feasibility of Spin‐ and Gradient‐Echo Dynamic Susceptibility Contrast MRI for Microvascular Characterization at 7 Tesla

NMR in Biomedicine, Volume 39, Issue 10, October 2026.
Spin‐ and‐gradient‐echo DSC MRI at 7 T allows for characterization of the microvasculature at an improved resolution and a reduced gadolinium‐based contrast agent dosage while maintaining increased vascular contrast. Ratios between normal‐appearing gray matter and white matter for relative cerebral blood volume and vessel size estimates were similar ...

Association between the perfusion/diffusion and diffusion/FLAIR mismatch: data from the AXIS2 trial.

, 2015
The perfusion-/diffusion-weighted imaging (PWI/DWI) mismatch and the diffusion/fluid attenuated inversion recovery (DWI/FLAIR) mismatch are magnetic resonance imaging (MRI) markers of evolving brain ischemia.

IL-6 Plasma Levels Correlate With Cerebral Perfusion Deficits and Infarct Sizes in Stroke Patients Without Associated Infections

Frontiers in Neurology, 2019
Introduction: We aimed to investigate several blood-based biomarkers related to inflammation, immunity, and stress response in a cohort of patients without stroke-associated infections regarding their predictive abilities for functional outcome and ...

Evidence Overload in England's Water Resources Management Plans: Model Abundance and the Transparency Failure

JAWRA Journal of the American Water Resources Association, Volume 62, Issue 5, October 2026.
ABSTRACT In England's water sector, statutory Water Resources Management Plans (WRMPs) have become increasingly model‐led and document heavy. While this expansion is intended to strengthen evidence‐based decision‐making, transparency, and accountability, in practice it has contributed to a transparency failure: an evidence base that is formally public ...

DWI-ASPECTS (Diffusion-Weighted Imaging–Alberta Stroke Program Early Computed Tomography Scores) and DWI-FLAIR (Diffusion-Weighted Imaging–Fluid Attenuated Inversion Recovery) Mismatch in Thrombectomy Candidates

, 2018
Background and Purpose— We aimed to study the intrarater and interrater agreement of clinicians attributing DWI-ASPECTS (Diffusion-Weighted Imaging–Alberta Stroke Program Early Computed Tomography Scores) and DWI-FLAIR (Diffusion-
