Deep grading for MRI-based differential diagnosis of Alzheimer's disease and Frontotemporal dementia

no code implementations25 Nov 2022 Huy-Dung Nguyen, Michaël Clément, Vincent Planche, Boris Mansencal, Pierrick Coupé

In this paper, we propose a deep learning based approach for both problems of disease detection and differential diagnosis.

Longitudinal detection of new MS lesions using Deep Learning

no code implementations16 Jun 2022 Reda Abdellah Kamraoui, Boris Mansencal, José V Manjon, Pierrick Coupé

First, we propose to use transfer-learning from a model trained on a segmentation task using single time-points.

Interpretable differential diagnosis for Alzheimer's disease and Frontotemporal dementia

no code implementations15 Jun 2022 Huy-Dung Nguyen, Michaël Clément, Boris Mansencal, Pierrick Coupé

However, differential diagnosis of these two types of dementia remains difficult at the early stage of disease due to similar patterns of clinical symptoms.

Towards better Interpretable and Generalizable AD detection using Collective Artificial Intelligence

no code implementations7 Jun 2022 Huy-Dung Nguyen, Michaël Clément, Boris Mansencal, Pierrick Coupé

Current deep learning-based approaches in this field, however, have a number of drawbacks, including the interpretability of model decisions, a lack of generalizability information and a lower performance compared to traditional machine learning techniques.

POPCORN: Progressive Pseudo-labeling with Consistency Regularization and Neighboring

no code implementations13 Sep 2021 Reda Abdellah Kamraoui, Vinh-Thong Ta, Nicolas Papadakis, Fanny Compaire, José V Manjon, Pierrick Coupé

Semi-supervised learning (SSL) uses unlabeled data to compensate for the scarcity of annotated images and the lack of method generalization to unseen domains, two usual problems in medical segmentation tasks.

DeepLesionBrain: Towards a broader deep-learning generalization for multiple sclerosis lesion segmentation

no code implementations14 Dec 2020 Reda Abdellah Kamraoui, Vinh-Thong Ta, Thomas Tourdias, Boris Mansencal, José V Manjon, Pierrick Coupé

Instead of proposing another improvement of the segmentation accuracy, we propose a novel method robust to domain shift and performing well on unseen datasets, called DeepLesionBrain (DLB).

Deep correction of breathing-related artifacts in real-time MR-thermometry

no code implementations10 Nov 2020 Baudouin Denis de Senneville, Pierrick Coupé, Mario Ries, Laurent Facq, Chrit Moonen

Real-time MR-imaging has been clinically adapted for monitoring thermal therapies since it can provide on-the-fly temperature maps simultaneously with anatomical information.

RegQCNET: Deep Quality Control for Image-to-template Brain MRI Affine Registration

no code implementations14 May 2020 Baudouin Denis de Senneville, José V. Manjon, Pierrick Coupé

In the current study, a compact 3D convolutional neural network (CNN), referred to as RegQCNET, is introduced to quantitatively predict the amplitude of an affine registration mismatch between a registered image and a reference template.

Accuracy of MRI Classification Algorithms in a Tertiary Memory Center Clinical Routine Cohort

no code implementations19 Mar 2020 Alexandre Morin, Jorge Samper-González, Anne Bertrand, Sebastian Stroer, Didier Dormont, Aline Mendes, Pierrick Coupé, Jamila Ahdidan, Marcel Lévy, Dalila Samri, Harald Hampel, Bruno Dubois, Marc Teichmann, Stéphane Epelbaum, Olivier Colliot

Using clinical routine T1-weighted MRI, we evaluated the classification performance of: 1) univariate volumetry using two AVS (volBrain and Neuroreader$^{TM}$); 2) Support Vector Machine (SVM) automatic classifier, using either the AVS volumes (SVM-AVS), or whole gray matter (SVM-WGM); 3) reading by two neuroradiologists.

Tensor-Based Grading: A Novel Patch-Based Grading Approach for the Analysis of Deformation Fields in Huntington's Disease

no code implementations23 Jan 2020 Kilian Hett, Hans Johnson, Pierrick Coupé, Jane Paulsen, Jeffrey Long, Ipek Oguz

In this work, we propose to combine the advantages of these two approaches by extending the patch-based grading framework with a new tensor-based grading method that enables us to model patterns of local deformation using a log-Euclidean metric.
