FLAIR MR sequence in the diagnosis and follow-up of low-grade astrocytomas [PDF]

Vojnosanitetski Pregled, 2005
Aim. To evaluate the sensitivity of fluid-attenuated inversion recovery (FLAIR) sequence in the diagnosis and follow-up of the patients with low-grade astrocytomas compared with T2-weighted (T2W) sequence. Methods.

CDC42 Might Be a Molecular Signature of DWI-FLAIR Mismatch in a Nonhuman Primate Stroke Model

Brain Sciences, 2023
No definitive blood markers of DWI-FLAIR mismatch, a pivotal indicator of salvageable ischemic penumbra brain tissue, are known. We previously reported that CDC42 and RHOA are associated with the ischemic penumbra.

Stability of MRI radiomic features according to various imaging parameters in fast scanned T2-FLAIR for acute ischemic stroke patients

Scientific Reports, 2021
From May 2015 to June 2016, data on 296 patients undergoing 1.5-Tesla MRI for symptoms of acute ischemic stroke were retrospectively collected. Conventional, echo-planar imaging (EPI) and echo train length (ETL)-T2-FLAIR were simultaneously obtained in ...

Aerodynamic analysis of toroidal propellers in forward flight [PDF]

INCAS Bulletin
Research is being conducted to develop a new generation of propellers that can enable quieter and more efficient flight. One promising development in this area are Toroidal propellers, for which the blades are shaped as a closed loop.

Postcontrast Fluid-Attenuated Inversion Recovery (FLAIR) Sequence MR Imaging in Detecting Intracranial Pathology

Radiology Research and Practice, 2020
Background. Imaging sequences for detection of meningeal and parenchymal lesions are critical in intracranial pathology. Our study analysed FLAIR MRI sequence for evaluating postcontrast enhancement. Objectives.

Predicting DWI-FLAIR mismatch on NCCT: the role of artificial intelligence in hyperacute decision making

Frontiers in Neurology, 2023
BackgroundThe presence of diffusion-weighted imaging (DWI) and fluid-attenuated inversion recovery (FLAIR) mismatch was used to determine eligibility for intravenous thrombolysis in clinical trials.

Simple quantitative measurement based on DWI to objectively judge DWI-FLAIR mismatch in a canine stroke model

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.

Visualization of white matter tracts using a non-diffusion weighted magnetic resonance imaging method: does intravenous gadolinium injection four hours prior to the examination affect the visualization of white matter tracts?

PLoS ONE, 2014
ObjectivesVisualization of white matter (WM)-tracts such as the corticospinal tract (CST), medial lemniscus (ML), and superior cerebellar peduncle (SCP) using delayed enhanced (DE)-heavily T2-weighted three-dimensional fluid-attenuated inversion-recovery

Experimental Imaging Study of Encephalomalacia Fluid-Attenuated Inversion Recovery (FLAIR) Hyperintense Lesions in Posttraumatic Epilepsy

Neural Plasticity, 2021
This study introduced new MRI techniques such as neurite orientation dispersion and density imaging (NODDI); NODDI applies a three-compartment tissue model to multishell DWI data that allows the examination of both the intra- and extracellular properties
