Ge mr750 3.0 tesla scanner

Whole-brain fMRI scans were performed using a GE MR750 3.0 Tesla Scanner (General Electric, USA). We used a gradient echo planar imaging (EPI) sequence with the following imaging parameters: TR = 2000 ms; TE = 30 ms; flip angle = 80°; FOV = 240 mm × 240 mm; matrix = 64 × 64; slice thickness = 3.2 mm, no gap; and slice number = 43 and 160 volumes. The slices covered the whole brain extending from the frontoparietal cortex to lower parts of the cerebellum. We also used 3D-BRAVO sequence to generate high-resolution 3D T1-weighted structural images, with these parameters: TR = 8.2 ms, TE = 3.2 ms, flip angle = 12°, FOV = 220 mm × 20 mm, matrix = 256 × 256, and slice thickness = 1 mm.

A GE-MR750 3.0 Tesla scanner was used to acquire images at the MRI Research Center, Peking University. The scanning included functional and anatomical imaging. T2*-weighted functional images were acquired in 40 axial slices that were parallel to the AC–PC line with no interslice gap, thus affording full-brain coverage. Functional images were collected using an echo-planar imaging sequence (33 axial slices, 4.2-mm slice thickness, TR = 2000 ms, TE = 30 ms, 3.5 × 3.5 × 4.2 mm voxel size, 90° flip angle, 224 × 224 mm field of view). Structural images were acquired using a three-dimensional sagittal T1-weighted magnetization-prepared rapid gradient echo (192 slices, 1-mm slice thickness, 1 × 1 × 1.0 mm voxel size, 12° flip angle, 450-ms inversion time, 256 × 256 mm field of view).

Images were acquired using a GE-MR750 3.0 Tesla scanner with a standard 8-channel head coil. The scanning included functional and anatomical imaging. T2*-weighted functional images were acquired, in an interleaved manner, in 40 axial slices parallel to the AC-PC line with no interslice gap, affording full-brain coverage. Images were acquired using an EPI pulse sequence, with a TR of 2000 ms, a TE of 30 ms, a flip angle of 90°, an FOV of 192 mm × 192 mm, and 3 mm × 3 mm × 3 mm voxels. A high-resolution, whole-brain structural scan (1 mm³ isotropic voxel MPRAGE) was acquired after functional imaging.
