FLAIR-only joint volumetric analysis of brain lesions and atrophy in clinically isolated syndrome (CIS) suggestive of multiple sclerosis

NeuroImage: Clinical, 2021
Background: MRI assessment in multiple sclerosis (MS) focuses on the presence of typical white matter (WM) lesions. Neurodegeneration characterised by brain atrophy is recognised in the research field as an important prognostic factor.

Advanced Magnetic Resonance Imaging in Glioblastoma: A Review [PDF]

, 2018
INTRODUCTION In 2017, it is estimated that 26,070 patients will be diagnosed with a malignant primary brain tumor in the United States, with more than half having the diagnosis of glioblas- toma (GBM).1 Magnetic resonance imaging (MRI) is a widely ...

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.

T1w/FLAIR ratio standardization as a myelin marker in MS patients

NeuroImage: Clinical, 2022
Introduction: Calculation of a T1w/T2w ratio was introduced as a proxy for myelin integrity in the brain of multiple sclerosis (MS) patients. Since nowadays 3D FLAIR is commonly used for lesion detection instead of T2w images, we introduce a T1w/FLAIR ...

Meta-analysis of death and myocardial infarction in the DEFINE-FLAIR and iFR-SWEDEHEART trials: a hypothesis generating note of caution [PDF]

, 2017
In patients with coronary heart disease, revascularization can improve symptoms and in certain high-risk subgroups may improve prognosis. Coronary angiography provides anatomical information and the physiological significance of a stenosis can be ...

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

Contrast enhanced FLAIR versus contrast enhanced T1W images in evaluation of intraparenchymal brain lesions

The Egyptian Journal of Radiology and Nuclear Medicine, 2022
Background Patients with suspected brain lesions are usually evaluated by means of intravenous contrast materials. These lesions may demonstrate enhancement through different mechanisms. At most institutions, CE-T1WI is the preferred sequence. FLAIR is a

Simultaneous lesion and neuroanatomy segmentation in Multiple Sclerosis using deep neural networks [PDF]

, 2019
Segmentation of both white matter lesions and deep grey matter structures is an important task in the quantification of magnetic resonance imaging in multiple sclerosis.

Utility of contrast-enhanced 3D STIR FLAIR imaging for evaluating pituitary adenomas at 3 Tesla

European Journal of Radiology Open, 2023
Purpose: To assess the usefulness of contrast-enhanced 3D STIR FLAIR imaging for evaluation of pituitary adenomas. Methods: Patients with pituitary adenomas underwent MR examinations including contrast-enhanced 3D STIR FLAIR and 2D T1-weighted (T1W ...

Contrast-enhanced fluid-attenuated inversion-recovery (FLAIR) versus contrast-enhanced T1 MRI in the evaluation of intracranial tumors: A comparative study

Rwanda Medical Journal, 2022
INTRODUCTION: At most institutions, the favored contrast MR sequence is T1-weighted imaging (T1WI). However, lesion enhancement is occasionally inconspicuous on T1WI.
