The impact of the DWI-FLAIR-mismatch in the ECASS-4 trial – A post hoc analysis [PDF]

European Stroke Journal, 2020
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

Radiomic signature of DWI-FLAIR mismatch in large vessel occlusion stroke. [PDF]

Journal of Neuroimaging, 2022
BACKGROUND AND PURPOSE: Ischemic diffusion-weighted imaging-fluid-attenuated inversion recovery (DWI-FLAIR) mismatch may be useful in guiding acute stroke treatment decisions given its relationship to onset time and parenchymal viability; however, it ...

DWI-FLAIR Mismatch at MRI Versus Infarct-Penumbra Mismatch on CT Perfusion [PDF]

Journal of the Belgian Society of Radiology, 2019
A 90-year-old female patient was brought to our hospital by ambulance after her husband found her somnolent and mute upon waking. Upon arrival, neurological and physical examinations showed spastic flexion of the right arm and deviation of gaze to the ...

High-Resolution IVIM MRI Characterizes Diffusion-Perfusion Properties of the Parasagittal Dura. [PDF]

NMR Biomed
Parasagittal dura demonstrates intermediate diffusion and elevated perfusion‐related IVIM metrics compared with brain parenchyma, reflecting its unique microfluidic environment at the CSF–dura interface. IVIM imaging of the parasagittal dura provides a rapid, noncontrast MRI approach to assess dural fluid transport and may offer a potential imaging ...

急性缺血性卒中DWI-FLAIR不匹配影像学判读研究进展（Research Advances in Imaging Interpretation of DWI-FLAIR Mismatch in Acute Ischemic Stroke）

Zhongguo cuzhong zazhi
在急性缺血性卒中（acute ischemic stroke，AIS）中，DWI-FLAIR不匹配是指MRI DWI序列上显示有急性梗死病灶（呈现高信号），而对应的FLAIR序列显示该区域呈等信号的一种影像学表现。DWI-FLAIR不匹配反映了梗死核心（不可逆损伤区）与缺血半暗带（潜在可挽救区）在空间分布上的差异。近年来研究表明，基于DWI-FLAIR不匹配的缺血半暗带评估有助于筛选仍存在可挽救脑组织的AIS患者，为发病时间不明（如醒后卒中）的患者是否适宜接受再灌注治疗提供了重要的影像学依据 ...

Neuroimaging of the ictal-interictal continuum: Where do we stand? A systematic review and meta-analysis of current evidence. [PDF]

Epilepsia Open
Abstract Objective Patterns within the ictal–interictal continuum (IIC) are frequently encountered in critically ill patients undergoing continuous electroencephalographic studies and may reflect ongoing ictal activity or secondary brain injury. Peri‐ictal neuroimaging abnormalities (PNA) have been described in association with status epilepticus (SE),

Predicting diffusion-FLAIR mismatch from B1000 and ADC without FLAIR: A deep learning-based approach [PDF]

Scientific Reports
Diffusion-FLAIR mismatch (DFM), defined as the discrepancy between diffusion-weighted imaging (DWI) and FLAIR sequences, is a key imaging biomarker used to identify patients with unclear symptom onset or those likely to benefit from recanalization ...

Automated DWI-FLAIR mismatch assessment in stroke using DWI only. [PDF]

Eur Stroke J
International audienceIn Acute Ischemic Stroke (AIS), mismatch between Diffusion-Weighted Imaging (DWI) and Fluid-Attenuated Inversion-Recovery (FLAIR) helps identify patients who can benefit from thrombolysis when stroke onset time is unknown (15% of ...

Treating ischaemic stroke with intravenous tPA beyond 4.5 hours under the guidance of a MRI DWI/T2WI mismatch was safe and effective

Stroke and Vascular Neurology, 2019
Purpose Clinical trials have provided evidence that treating patients with acute ischaemic stroke (AIS) beyond 4.5 hours was feasible. Among them using MRI diffusion-weighted imaging/fluid attenuation inversion response (DWI/FLAIR) mismatch to guide ...
