The impact of the DWI-FLAIR-mismatch in the ECASS-4 trial – A post hoc analysis [PDF]
European Stroke Journal, 2020 Abstract Introduction To investigate the impact of a mismatch between diffusion-weighted imaging (DWI) and fluid attenuated inversion recovery (FLAIR) on functional outcome in patients with acute stroke in a prolonged time window or unknown time of symptom onset randomized to intravenous ...

Simple quantitative measurement based on DWI to objectively judge DWI-FLAIR mismatch in a canine stroke model [PDF]
Diagnostic and Interventional Radiology, 2015 PURPOSEDiffusion-weighted imaging (DWI) - fluid attenuated inversion recovery (FLAIR) mismatch was proven useful to time the onset of wake-up stroke; however, identifying the status of FLAIR imaging has been mostly subjective.

COVID-19 Associated Wake-Up Stroke Treated With DWI/FLAIR Mismatch Guided Intravenous Alteplase: A Case Report. [PDF]
Neurologist, 2021 Introduction: Wake-up strokes are challenging to manage due to unknown time of onset. Recently, the wake-up trial demonstrated that recombinant tissue plasminogen activator (rtPA) could be administered based on the magnetic resonance imaging (MRI)- diffusion weighted imaging/fluid attenuated inversion recovery mismatch.

Predictive value of DWI-FLAIR Mismatch in patients with Ischemic Stroke and receiving Endovascular treatment beyond Time Window. [PDF]
Pak J Med Sci, 2021 Objective: To investigate the efficacy and safety of endovascular treatment in patients having acute ischemic stroke with over-time window under DWI-FLAIR mismatch. Methods: From January 2018 to January 2020, 80 patients who met the research criteria in the First Central Hospital of Baoding, China were selected.

Favorable Bridging Therapy Based on DWI-FLAIR Mismatch in Patients with Unclear-Onset Stroke. [PDF]
AJNR Am J Neuroradiol, 2016 Standard selection criteria for revascularization therapy usually exclude patients with unclear-onset stroke. Our aim was to evaluate the efficacy and safety of revascularization therapy in patients with unclear-onset stroke in the anterior circulation and to identify the predictive factors for favorable clinical outcome.We retrospectively analyzed 41 ...

Automated Assessment of the DWI-FLAIR Mismatch in Patients with Acute Ischemic Stroke: Added Value to Routine Clinical Practice. [PDF]
AJNR Am J NeuroradiolThe DWI-FLAIR mismatch is used to determine thrombolytic eligibility in patients with acute ischemic stroke when the time since stroke onset is unknown. Commercial software packages have been developed for automated DWI-FLAIR classification. We aimed to use e-Stroke software for automated classification of the DWI-FLAIR mismatch in a cohort of patients

O-001 DWI-FLAIR mismatch does not predict time of stroke onset in DEFUSE 3 patients [PDF]
Oral Abstracts, 2020 Introduction Acute stroke patients with unclear time of symptom onset have traditionally been ineligible for treatment with IV tissue plasminogen activator (tPA) based on a strict time window of treatment within 4.5 hours of symptom onset. Recently, the use of DWI-FLAIR mismatch to identify patients within the 4.5 hour time window has been suggested ...
