MRI acquisition details

Diffusion‐weighted images were acquired using a spin‐echo, single‐shot, echo‐planar imaging pulse sequence (8 × b = 0 s/mm², 40 × b = 1300 s/mm²; TR/TE = 8000/84.5 ms; flip angle = 90°; FOV = 240 mm; 96 × 96 acquisition matrix; 2.5 × 2.5 × 2.5 mm³ isotropic voxel resolution). T1‐weighted structural images were acquired using a 3D inversion recovery prepared fast spoiled gradient‐echo FSPGR‐BRAVO sequence (TI = 450 ms; TR/TE = 8.1/3.2 ms; flip angle = 12°; FOV = 256 mm; 256 × 256 acquisition matrix; 1 × 1 × 1 mm³ isotropic voxel resolution). T2‐weighted images were acquired using a 3D fluid‐attenuated inversion recovery (FLAIR) pulse sequence (TI = 1871 ms; TR/TE = 6000/122.3 ms; flip angle = 90°; FOV = 256 mm; 256 × 256 acquisition matrix; 1 × 1 × 1 mm³ isotropic voxel resolution).
