我们的研究评估了T2减毒倒置恢复(FLAIR)错配符号在检测24个低级和高级神经胶质瘤患者的异柠檬酸脱氢酶(IDH)突变中的作用。两者之间的关联是通过单变量和多元逻辑回归分析实现的。两位评估者之间在检测T2-FLAIR不匹配信号方面存在实质性共识(Cohen的kappa系数为0.647)。当与肿瘤同质性程度同时注册时,T2-FLAIR不匹配体征...
最近,报道了磁共振成像(magneticresonance imaging, MRI)中T2加权液体衰减反转恢复(T2-weighted-Fluid-Attenuated Inversion Recovery, T2/FLAIR)高信号与CVD之间的相关性,但T2/FLAIR高信号与侵袭性症状之间的关系尚未见报道。因此来自美国华盛顿大学医学院神经外科的Gregory J. Zipfel等人开展了此项研究,在大型dAVF患者...
By employing a novel voxel‐based model of the MRI signal, we test whether the extravasation of fluid and plasma proteins in the brain tissue and/or sulcal spaces can indeed explain the T2 FLAIR hyperintensities characteristic for ARIA〦. The modelled MRI voxel consists of myelin (my), ...
Introduction: Amide Proton Transfer Imaging(APT)is an MRI imaging method that images the increased concentration of amide groups in tumors and is expected to be clinically applied to the diagnostic imaging of gliomas.On the other hand,T2/FLAIR mismatch sign(T2/FLms)has been proposed as an MRI ...

T2 Weighted and T2 FLAIR Axial ImageImaging the human parts to study the medical aliments is a challenging task ever carried out in the world today. There are various segmentation techniques for processing the medical images. This paper is dedicated to study the MRI brain images of various ...
Interobserver agreement was significantly higher for conventional FLAIR relative to fast FLAIR for small (<5mm) foci of T2 in the white matter. Otherwise, interobserver agreement was not different between the fast and conventional sequences. For awake subjects, fast sequences had significantly fewer...
Purpose/Objective(s) Analyzing the effect of time-delayed contrast-enhanced (CE) T2-fluid-attenuated inversion-recovery (T2-FLAIR) on gross tumor target volume (GTV) determination of brain metastases (BMs), and exploring its feasibility for improving the accuracy of GTV determination in BMs. ...
SVMs are the basis of a machine-learning technique that has been used for segmentation and classification of medical images. The database consists of two weighted images: T2 and FLAIR. The proposed system mainly consists of two stages. The first stage performs pre-processing the MRI image, ...
