Qualitative Scores^* for T2W 3D-SPACE and T2W 2D-TSE Sequences

Note.-^*Aqueductal patency was scored on relative 4-point scale, with 0 = no flow void in aqueduct, through third ventricle to apex of fourth ventricle and 3 = flow void in all of them. AC = Arnold Chiari malformation, CH = communicating hydrocephalus, PAS = primary aqueduct stenosis, SAS = secondary aqueduct stenosis, SPACE = sampling perfection with application optimized contrast using different flip angle evolutions, TSE = turbo spin echo, T2W = T2-weighted, 2D = two-dimensional, 3D = three-dimensional
