“…Axial multidirectional diffusionweighted images with fat saturation were acquired to characterize diffusion tensor imaging derived parameters as previously described. 4 A 3D radial sequence was used to obtain sodium images using the following parameters: TR = 110 msec, TE = 0.2 msec, FoV = 180 × 180 × 180 mm 3 , voxel resolution = 2 × 2 × 2 mm 3 , 10 4 radial spokes, bandwidth = 276 Hz/px, TA = 1102 sec. High-resolution T 1 -weighted images were used as reference images (GRE, TR = 13 msec, TE = 5 msec, in-plane FoV = 180 × 180 mm², matrix = 512 × 512, 88 slices, ST = 2 mm, bandwidth = 260 Hz/px, TA = 587 sec).…”
