Machine Learning Applications in Traumatic Brain Injury: A Spotlight on Mild TBI

no code implementations8 Jan 2024 Hanem Ellethy, Shekhar S. Chandra, Viktor Vegh

As such, we review the state-of-the-art Machine Learning (ML) techniques applied to clinical information and CT scans in TBI, with a particular focus on mTBI.

Enhancing mTBI Diagnosis with Residual Triplet Convolutional Neural Network Using 3D CT

no code implementations23 Nov 2023 Hanem Ellethy, Shekhar S. Chandra, Viktor Vegh

To address these challenges, we propose a Residual Triplet Convolutional Neural Network (RTCNN) model to distinguish between mTBI cases and healthy ones by embedding 3D CT scans into a feature space.

Interpretable 3D Multi-Modal Residual Convolutional Neural Network for Mild Traumatic Brain Injury Diagnosis

no code implementations22 Sep 2023 Hanem Ellethy, Viktor Vegh, Shekhar S. Chandra

Notably, in comparison to the CT-based Residual Convolutional Neural Network (RCNN) model, the MRCNN shows an improvement of 4. 4% in specificity and 9. 0% in accuracy.

Robust, fast and accurate mapping of diffusional mean kurtosis

no code implementations30 Nov 2022 Megan E. Farquhar, Qianqian Yang, Viktor Vegh

In summary, our findings suggest robust, fast and accurate estimation of mean kurtosis can be realised within a clinically feasible diffusion weighted magnetic resonance imaging data acquisition time.

Instant tissue field and magnetic susceptibility mapping from MR raw phase using Laplacian enabled deep neural networks

2 code implementations15 Nov 2021 Yang Gao, Zhuang Xiong, Amir Fazlollahi, Peter J Nestor, Viktor Vegh, Fatima Nasrallah, Craig Winter, G. Bruce Pike, Stuart Crozier, Feng Liu, Hongfu Sun

In addition, experiments on patients with intracranial hemorrhage and multiple sclerosis were also performed to test the generalization of the novel neural networks.

CNNs and GANs in MRI-based cross-modality medical image estimation

no code implementations4 Jun 2021 Azin Shokraei Fard, David C. Reutens, Viktor Vegh

Generative adversarial networks (GANs) use CNNs as generators and estimated images are discriminated as true or false based on an additional network.

Improving FLAIR SAR efficiency at 7T by adaptive tailoring of adiabatic pulse power using deep convolutional neural networks

1 code implementation19 Nov 2019 Shahrokh Abbasi-Rad, Kieran O'Brien, Samuel Kelly, Viktor Vegh, Anders Rodell, Yasvir Tesiram, Jin Jin, Markus Barth, Steffen Bollmann

Purpose: The purpose of this study is to demonstrate a method for Specific Absorption Rate (SAR) reduction for T2-FLAIR MRI sequences at 7T by predicting the required adiabatic pulse power and scaling the amplitude in a slice-wise fashion.
