Multi b value diffusion study in the human spinal cord was performed in-vivo on the group of volunteers. The b factor varied up to 7000 s/mm2 in ten steps. Non mono-exponential signal intensity decay was observed and data were fitted to the bi-exponential diffusion model, using a IDL based, in-house written software. Fast and slow components was calculated for GM and WM structures. The maps of diffusion coefficients and fractions were also created.
