Diffusion Tensor Brain MRI in the Detection of Structural Abnormality of the White Substance in Concussion

"The imaging will be carried out on the technical stage of the 3T MRI Research of the University Hospital of Clermont-Ferrand with the following sequences:~\- For traumatized and healthy subjects: MRI 3 Teslas (3D T1, T2 axial TSE, T2\* axial, SWI axial, Sagittale cube FLAIR, DTI 20-direction sequence) The image processing will be carried out within the radiology department: morphological analysis and analysis of tractography and diffusion parameters (FA and ADC, diffusivity) on predefined and reproducible Regions of Interest (ROIs).~Regions Of Interest include: splenium of the corpus callosum, internal capsule, cortico-spinal tract, optic radiation."
