In this study, criteria for threshold selection are anatomically defined.<\/jats:p><\/jats:sec><jats:sec><jats:title>METHODS<\/jats:title><jats:p>T2 MR images (<jats:italic>n<\/jats:italic> = 7 cases) were analyzed using 3\u2010dimentional software. Maximal\u2013minimal thresholds were selected in standardized blocks of 50 slices of the dural sac ending caudally at the L5\u2010S1 intervertebral space (caudal blocks) and middle L3 (rostral blocks). Maximal CSF thresholds: threshold value was increased until at least one voxel in a CSF area appeared unlabeled and decreased until that voxel was labeled again: this final threshold was selected. Minimal root thresholds: thresholds values that selected cauda equina root area but not adjacent gray voxels in the CSF\u2013root interface were chosen.<\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS<\/jats:title><jats:p>Significant differences were found between caudal and rostral thresholds. No significant differences were found between expert and nonexpert observers. Average max\/min thresholds were around 1.30 but max\/min CSF volumes were around 1.15.
