Neuroinflammation Imaging Lab at UCLouvain

The Louvain Neuroinflammation Imaging Lab (NIL)

The activity of the Louvain Neuroinflammation Imaging Lab (NIL) focuses on several projects, all aimed at characterizing and modeling the pathogenesis of multiple sclerosis (MS) using advances magnetic resonance imaging (MRI) methods.

The standard MRI protocols routinely used for MS diagnosis have a limited specificity for the underlying brain pathology, possibly resulting in wrong diagnosis and incorrect treatments for patients. At the same time, using the same routine imaging protocols, the pathological heterogeneity of what is currently diagnosed as "MS" is probably underestimated, limiting the application of MRI as a tool to guide individually tailored treatment. The major goal of our research is to combine advanced and more established imaging, laboratory and clinical data in order i) to "dissect" the pathological heterogeneity between MS and mimicking disorders, ii) identify different pathological entities within the "MS spectrum" itself and, iii) evaluate clinical course/response-to-treatment based on the extracted multimodal features.

Thanks to the very productive collaboration between highly experienced clinicians (at Cliniques Universitaires Saint-Luc), talented neuroimaging scientists (NEUR, Institute of Neuroscience (IoNS), UCLouvain) and neuroimmunologists (CEMO, Institute of Neuroscience (IoNS), UCLouvain), we perform advanced MRI on neuroinflammatory patients, and we study the association between imaging, clinical and biological disease biomarkers.
