Example of geometric and hydrodynamic characterization of the SSS for a healthy adult male subject based on subject specific MRI measurements and engineering post-processing techniques described by Sass et al. [35]. Axial distribution of dura, spinal cord and SSS (dura + spinal cord) perimeter (a), dura, spinal cord and SSS area (b), hydraulic diameter (c), Reynolds and Womersley number (d), peak CSF flow rate at systole and diastole (e), mean CSF flow velocity at systole and diastole (f). Systolic flow is directed towards the feet
