Detailed Activities

The general objective of the Spinal Cord MR Imaging research group is to improve the non invasive characterization of the spinal cord impairments and to help in the description of the spinal cord pathophysiological mechanisms using quantitative and multi-parametric Magnetic Resonance Imaging.

My objective during my thesis, co-directed between Marseille and Montreal, is to carry out a structural analysis of the spinal cord in cervical spondylotic myelopathy and central cord syndrome using Diffusion and Perfusion weighted images at 7T to find new biomarkers. Then, to study the stresses and strains during biomechanical simulation in order to identify biomarkers related to those found in MRI.

This project aims to combine MR and biomechanical computational modeling in order to provide an extensive and multi-physic description of traumatic and degenerative spinal cord pathologies (International Research Laboratory (IRL/LIA) “iLab-Spine ”, France/Canada).
