Skyra 3t human mri scanner

Neuroimaging was accomplished using the Siemens Skyra 3T Human MRI scanner located at the Biomedical Imaging Center at the University of Texas at Austin. Functional data were acquired with a 32-channel head-coil, with 3mm isotropic resolution (TR = 2000ms; TE = 29ms; FoV = 228; 48 slices). A multi-band factor of 2 was used with automatic AC/PC alignment. As discussed in Hennings et al., (2020)^{42 (link)}, due to a computer malfunction, 2 subjects had slightly different acquisition parameters on Day 1 (TR = 2230ms; 66 slices), which were accounted for during preprocessing and analysis. An T1-weighted 3d MPRAGE scan (TR = 1900ms; 1mm isotropic resolution) was collected on Day 1 to aid in functional image registration and region of interest definition.

Scanning was completed using the Siemens Skyra 3T Human MRI scanner located at the Biomedical Imaging Center at the University of Texas at Austin. Functional data were acquired with a 32-channel head-coil. Functional image resolution was 3mm isotropic voxels (TR = 2000ms, TE= 29ms; FoV = 228mm; n(Slices) = 48). A multi-band factor of 2 was used with AC/PC auto alignment. Due to a computer malfunction, 2 subjects had slightly different acquisition parameters on day 1 (TR=2230ms, n(Slices) = 66), which were accounted for during preprocessing and analysis. An additional high resolution T1-weighted 3D MPRAGE scan (TR=1.9s, 1mm isotropic voxels) was collected on day 1 to aid in registration and region-of-interest definition.
