Brain MRI images were obtained parallel to the orbitomeatal line using the following parameters: TR/TE 9000/120 ms, pixel spacing 0.449 mm/0.449 mm, FOV 230×230 mm, and slice thickness 5 mm for fluid-attenuated inversion recovery (FLAIR); TR/TE 9000/100 ms, pixel spacing 0.240 mm/0.240 mm, FOV 230×230 mm, and slice thickness 5 mm for T2 weighted images (T2); and TR/TE 600/16 ms, pixel spacing 0.449 mm/0.449 mm, FOV 250×250 mm, and slice thickness 5 mm for gradient recalled echo (GRE) imaging.
