• sagittal acquisition, 0.6 × 0.6 × 0.6 mm

• voxel size, 230 x 230 x 180 mm field of view, effective echo

• time 25 ms

• repetition time of 55 ms

• parallel imaging factor 2

• 10-degree flip angle

• echo planar imaging factor or multiecho options if available

• scan duration of 6 minutes or less
