Diffusion-Weighted Imaging and Fluid-Attenuated Inversion Recovery Quantification to Predict Diffusion-Weighted Imaging-Fluid-Attenuated Inversion Recovery Mismatch Status in Ischemic Stroke With Unknown Onset

open access: yes, 2022
BACKGROUND: Visual rating of diffusion-weighted imaging (DWI)-fluid-attenuated inversion recovery (FLAIR) mismatch can be challenging. We evaluated quantification of DWI and FLAIR to predict DWI-FLAIR mismatch status in ischemic stroke.

Large vessel occlusion mediated fluid attenuated inversion recovery signal intensity ratio is associated with stroke within 4.5 h

open access: yesFrontiers in Neurology
IntroductionThe primary objective was to investigate the value of the fluid attenuated inversion recovery (FLAIR) signal intensity ratio (SIR) in identifying stroke within 4.5 h.

Clinical Efficacy of Revascularization Surgery for Moyamoya Angiopathy: Long‐Term Results of a European Cohort

open access: yesEuropean Journal of Neurology, Volume 33, Issue 6, June 2026.
In this European cohort of 276 patients with Moyamoya angiopathy, surgical revascularization, predominantly combined bypass surgery targeting the MCA territory via a mini‐craniotomy, was associated with low perioperative complication rates (6.3%) and stroke rates (2.6%).

A Real-world Study of MRI-guided Intravenous Thrombolytic Therapy in Acute Ischemic Stroke [PDF]

open access: yesZhongguo quanke yixue
Background Ischemic stroke has a high rate of disability and mortality, and for some patients, the onset time is difficult to confirm, making treatment for these patients particularly important. Objective To explore the efficacy and safety of intravenous

Wake up stroke and stroke of unknown onset: a critical review

open access: yesFrontiers in Neurology, 2014
Patients who wake up with an ischemic stroke, account for a large number of the total stroke population, due to circadian morning predominance of stroke. Currently, this subset of patients is excluded from revascularization-therapy since no exact time of

Labeling of lesions in DWI imaging according to the FLAIR pattern.

open access: yes, 2014
A) In case of a FLAIR lesion encompassing the whole DWI-lesion, the hyperintensity was delineated as a region of interest (ROI) (A, second row). The FLAIR-ROI was then copied on the DWI and filled with 6 mm circular ROIs (A, third row)).

Deep learning to identify stroke within 4.5 h using DWI and FLAIR in a prospective multicenter study

open access: yesScientific Reports
To enhance thrombolysis eligibility in acute ischemic stroke, we developed a deep learning model to estimate stroke onset within 4.5 h using diffusion-weighted imaging (DWI) and fluid-attenuated inversion recovery (FLAIR) images. Given the variability in

More than half of patients with wake-up stroke have slept through their stroke onset

open access: yesJournal of Stroke and Cerebrovascular Diseases
Background: Conventional time-from-onset decision-making for use of reperfusion therapies in acute ischemic stroke is challenged by patients with wake-up strokes (WUS) in whom onset time is uncertain.

Prospective study on the mismatch concept in acute stroke patients within the first 24 h after symptom onset - 1000Plus study

open access: yesBMC Neurology, 2009
Background The mismatch between diffusion weighted imaging (DWI) lesion and perfusion imaging (PI) deficit volumes has been used as a surrogate of ischemic penumbra.
