Description du projet
Un cadre basé sur l’IRM améliore le diagnostic des troubles neurologiques
L’imagerie par résonance magnétique (IRM) est la méthode d’imagerie standard utilisée pour le diagnostic et le suivi de nombreuses maladies neurologiques telles que la sclérose en plaques. Toutefois, son application dans la pratique clinique se limite principalement à l’identification visuelle des principales anomalies tissulaires, et non des anomalies subtiles. L’objectif principal du projet CDS-QUAMRI, financé par l’UE, est de développer un système d’aide à la décision clinique qui exploite la puissance de l’IRM pour le diagnostic des troubles neurologiques et psychiatriques, lequel manque souvent de critères objectifs. Le consortium intégrera différentes modalités d’IRM et d’apprentissage automatique dans un cadre unique. Le système se concentrera dans un premier temps sur la dépression majeure et la sclérose en plaques, qui serviront de base à l’élaboration de futures prises de décision cliniques en neurosciences.
Objectif
A large number of neurological and psychiatric disorders lack objective criteria for primary diagnoses, early differential diagnosis with regard to subtypes in treatment response and disease progression or effective therapy monitoring resulting in a tremendous negative socio-economic impact. Scientific studies based on advanced MRI methods indicate that related patients show specific subtle changes in multiple MRI readouts that are only detectable by quantitative approaches. Existing tools for MRI data analysis are largely insufficient to maximise the use of advanced modality based, diverse and complex MRI data with deficiencies existing mainly in interoperability as well as data organisation, integration, analysis and exploitation in clinical decision making.
Hence, the development of a clinical decision support system for neurological and psychiatric disorders is envisioned that is based on multimodal quantitative magnetic resonance imaging, advanced feature extraction and multi-parametric classification. To that the quantitative analysis of structural, functional and metabolic MRI data (11 modalities) shall be fully integrated into a single software framework for the first time; support of large data, interoperability and access for non-expert users shall be enabled and a machine learning based classification module shall be developed. The quantification and feature extraction algorithms for metabolic, perfusion, diffusion and functional imaging shall be enhanced to access the full information content of the data independent of vendor specific scan protocols as required for future use in diagnostics, stratification and monitoring of patients. The envisioned clinical decision support system shall be tested, optimized and demonstrated for major depression and multiple sclerosis, but can be extended to additional disorders by enabling large scale clinical trials and more widespread use in neuroscience as a basis for the future clinical decision making.
