Retrospective dataset method overview. To compare the PEPTIDE and EPTI methods using identical in vivo data, complete EPTI acquisitions were performed with differing in-plane rotations. From this, the central k_y-segments from each acquisition could be taken to form a PEPTIDE dataset, that could be compared with the reconstruction from a complete EPTI dataset. To investigate motion, additional acquisitions were also performed with shifts in the subject head position, from which a k_y-segment could be taken to replace the corresponding segment in the stationary datasets for both PEPTIDE and EPTI.
