Image acquisition
A GE Discovery MR750 3.0T MRI scanner was used for imaging. The subjects underwent structural and BOLD functional imaging, and the scanning range was from the frontal-parietal to the base of skull, covering the entire brain. The scanning parameter settings: The structural image was acquired using the weighted fast scrambled phase gradient echo sequence technique. This allowed for acquiring the axial weighted images of T1W1 and T2W1. The scanning parameters were as follows: a repetition time of 1900 ms, a field of view set to 256 × 256 cm, an echo time of 2.26 ms, a matrix size of 256 × 256, and a scanning time of 7 min. Additionally, BOLD functional imaging was performed using the gradient echo sequence technique with a single excitation planar echo to acquire the information function. Scanning parameters: The repetition time is 2000 ms, the time point is 240, the echo time is 30 ms, the number of layers is 30, the layer thickness is 5 mm, the matrix is set to 64 × 64, the field of view is set to 256 × 256 cm, the flip angle is 90°, and the scanning time is 8 min.
