32 channel prisma head coil

Subjects were scanned on a Siemens 3T Prisma with an 80 mT gradient coil and a Siemens 32- channel Prisma head coil (32 (link)). T1w multi-echo MP-RAGE scans were acquired with the following acquisition parameters: voxel size=.8 mm isotropic, 4 echoes per line of k-space, FOV = 256 x 240 x 166 mm, matrix = 320 x 300 x 208 slices, 7.7% slice oversampling, GRAPPA = 2, pixel bandwidth = 744 Hz/pixel, TR = 2500 ms, TI = 1000 ms, TE = 1.8/3.6/5.4/7.2 ms, FA = 8 degrees. Motion-induced re-acquisition were allowed for up to 30 TRs. Multi-shell diffusion MRI (dMRI) scans were acquired with the following acquisition parameters: 1.5 mm isotropic voxel, TR=3.23 s, MB factor=4. dMRI data was collected using 185 diffusion-encoding directions split into two runs (92-93 directions per scan) and acquired twice with opposite phase-encoding directions (AP and PA), resulting in a total of 4 runs. Two shells (b=1500 s/mm², 3000 s/mm²) were interleaved within each dMRI run with 28 b=0 s/mm² volumes equally interspersed across all the scans.

Subjects were scanned on a Siemens 3T Prisma with an 80 mT gradient coil and a Siemens 32‐channel Prisma head coil (Harms et al., 2018 (link)). T1w multiecho MP‐RAGE scans were acquired with the following acquisition parameters: voxel size = 0.8 mm isotropic, 4 echoes per line of k‐space, FOV = 256 × 240 × 166 mm, matrix = 320 × 300 × 208 slices, 7.7% slice oversampling, GRAPPA = 2, pixel bandwidth = 744 Hz/pixel, TR = 2500 ms, TI = 1000 ms, TE = 1.8/3.6/5.4/7.2 ms, and FA = 8 degrees. Motion‐induced re‐acquisition was allowed for up to 30 TRs.
