Team "Functional Neuroimaging and Brain Perfusion"

Director: Emmanuel BARBIER

Our multidisciplinary team works on the development of innovative techniques for acquisition and analysis for Magnetic Resonance Imaging and Spectroscopy (MRI and MRS) and on their preclinical and clinical evaluation in neurosciences.

Research themes and techniques used

The research field of the team is in vivo biomedical magnetic resonance imaging (MRI). Our aims are the development, the validation and the application of in vivo MRI methods in the field of the clinical, biological and cognitive neuroscience. Since 2012, the team and the MRI facility IRMaGe are members of the national infrastructures 'France Life Imaging (FLI)'. The studies are performed on a preclinical and a clinical levels. They imply the coexistence of two overlapping components, one centered on the development of methods, the other on their evaluation. This duality is reflected in the multidisciplinary backgrounds of the members of the team, from physics to life sciences. More specifically, we address:

  • Development of functional and physiological imaging 
    We develop new imaging tools to characterize brain microvascularization: vessel size index (VSI), permeability of the vessel wall, blood volume (CBV) and blood flow (CBF), tissue oxygen saturation (StO2, quantitative BOLD), and cerebrovascular vasoreactivity. Based on these physiological information, we develop advanced functional MRI (fMRI) technique (e.g. joint detection estimation, in collaboration with Inria and Neurospin) and functional connectivity MRI (e.g. graph-based approach, in collaboration with GIPSA). We pursue these developments to improve the use of fMRI in patients. Our expertise in fMRI serves also numerous collaborations in cognitive neuroscience (visual, motor, auditory and olfactory systems) and neurology (brain tumor, stroke, coma, brain trauma, aging).

  • Development of imaging biomarker
    To exploit the structural, metabolic and perfusion data collected with MRI, we develop innovative tools for automated information extraction. We developed the approach LOCUS, based on Markovien models in a Baysian framework, to automatically segment tissue structures and brain lesions. We also exploit multiparametric MRI to obtain fingerprints of healthy and diseased tissues (coll. Inria).

  • Imaging-guided therapy
    Based on MRI, we evaluate advanced therapeutic strategies, such as microbeam X-ray therapy or anti-angiogenic therapies against brain tumors, stem cells therapy in the context of stroke and anti-oedematous therapy in the context of brain trauma. Since 2012, the team is par of the national infrastructure ECELL FRANCE, which supports the development of the therapeutic strategies based on adult mesenchymal stem cells.
