T2-weighted MRI data were collected as three volumes, a craniocervical, b thoracic, c Lumbosacral. A variety of artifacts exist in and around the SSS, d–f including the anterior spinal artery (ASA), left and right vertebral arteries (LV and LR), epidural space (ES), dura mater (DM), spinal cord (SC), and dorsal and ventral nerve rootlets (NR) in particular near the cauda equina. Note: the 3D geometry provided in this manuscript only includes the CSF within the spine below the foramen magnum (L left, R right, A anterior, P posterior)
