Diagnostic value of 3D-FLAIR magnetic resonance sequence in detection of white matter brain lesions in multiple sclerosis

Egyptian Journal of Radiology and Nuclear Medicine, 2020
Background MS is common demyelinating disease in which standard T2 and 2D-FLAIR MRI sequences play important role in its diagnosis. Recently, 3D-FLAIR sequence is used and has a role that is evaluated compared to standard sequences.

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 ...

A GAN-Based Multi-Sensor Data Augmentation Technique for CNC Machine Tool Wear Prediction

IEEE Access, 2023
The prediction of CNC machine tool wear is limited due to the scarcity of data in industry. A sufficient amount of experimental and real-live factory data is missing to train accurate supervised machine learning prediction models.

Reducing Slipstream Velocities Experienced in Proximity to High-Speed Trains

Fluids, 2022
Slipstream wake structures generated by the passing of high-speed rail vehicles represent a hazard to passengers and workers in close proximity. In this article, the possibility of reducing peak slipstream velocities through the implementation of angled ...

Role of Shape and Kinematics in the Hydrodynamics of a Fish-like Oscillating Hydrofoil

Journal of Marine Science and Engineering, 2023
In the present two-dimensional numerical study, we investigate the roles of geometrical parameters of a hydrofoil (shape/curvature of the leading and trailing edges and thickness) and kinematic parameters (phase difference between heave and pitch (ϕ)) on

Impact of Inversion Time for FLAIR Acquisition on the T2-FLAIR Mismatch Detectability for IDH-Mutant, Non-CODEL Astrocytomas

Frontiers in Oncology, 2021
The current research tested the hypothesis that inversion time (TI) shorter than 2,400 ms under 3T for FLAIR can improve the diagnostic accuracy of the T2-FLAIR mismatch sign for identifying IDHmt, non-CODEL astrocytomas.

Diagnostic value of three-dimensional cube fluid attenuated inversion recovery imaging and its axial MIP reconstruction in multiple sclerosis

The Egyptian Journal of Radiology and Nuclear Medicine, 2022
Background Magnetic resonance imaging is regarded as one of the most important markers for multiple sclerosis. It can detect lesions in order to establish dissemination in time and space, which would aid in the diagnosis.

Fluid-attenuated inversion-recovery MR sequence in the evaluation of low-grade astrocytomas [PDF]

Archive of Oncology, 2002
(Conclusion) Flair was found to be better for detection of the lesion and for definition of its margins in comparison with T2W se and PD sequences (6).
