Reading #fMRI methods when it's not your field sounds like a psychedelic voyage:
"Functional scans were collected using a T2*-weighted echo-planar imaging sequence with a multi-band acceleration factor of 4. A field map with dual echo-time images was acquired to correct for geometric distortions due to susceptibility-induced field inhomogeneities. Structural scans were acquired using a T1-weighted MPRAGE sequence with 1x1x1mm voxel resolution. We discarded the first six volumes to allow for scanner equilibration."
