Hd 750 w 3.0 t mri scanner

Structural MRI images were acquired on a General Electric HD 750 w 3.0 T MRI scanner with an 8-channel head-coil (General Electric, Waukesha, WI, United States). Structural imaging included T1-weighted three-dimensional (3D-T1), axial T2-weighted, and fluid-attenuated inversion recovery images. According to axial T2-weighted and fluid-attenuated inversion recovery images, subjects with abnormalities other than atrophy, or leukoaraiosis were excluded. The 3D-T1 images were collected using a fast-spoiled gradient recalled echo sequence [TR = 8.5 ms, TE = 3.2 ms, Inversion time (TI) = 450 ms, Matrix 256 × 256, FOV 256 mm × 256 mm, flip angle = 12°, and slice thickness of 1.0 mm without intervals]. The total scan duration for 3D-T1 image acquisition was 4 min, 30 s.

Structural and resting state MRI images were acquired using a General Electric HD 750 W 3.0 T MRI scanner with an 8‐channel head‐coil (General Electric). Seed‐based resting‐state functional connectivity (RSFC) analysis was employed to explore neuromechanisms underlying choice impulsivity in migraineurs. Seed points were defined as spheres of 4‐mm radii and included the left vSTR (left vSTR MNI coordinates: −10, 10, 2) and right vSTR (10, 12, −4) (Niddam et al., 2023 (link)). rs‐fMRI analysis was performed using the advanced edition of the Data Processing Assistant for Resting‐State Functional software, based on the statistical parametric mapping software package (SPM12; www.fil.ion.ucl.ac.uk/spm).
