We acquired anatomical MRI and DTI data on a 3.0T MR scanner (Achieva TX 3.0T; Philips Medical Systems) using a 32‐element sensitivity‐encoding head coil. A 3D fast field echo T1‐weighted sequence was used for anatomical MRI (TR/TE = 7.0/3.3 ms, FOV = 220 mm, 210 slices, acquisition voxel size = 0.86 × 0.86 × 0.9 mm, and a slice thickness = 0.9 mm). DTI images were acquired using a single‐shot spin‐echo echoplanar imaging diffusion sequence with fifty‐five 2.5‐mm slices (no interslice gap), TR/TE = 6,421/69 ms, FOV = 224 mm, acquisition voxel size = 2.0 × 2.0 × 2.5 mm, and 2b values of 0 and 1,000, 15 directions.
