A magnetic resonance imaging scanner ( 10 ) includes a main magnet ( 12 ), magnetic field gradient coils ( 16 ), and one or more radio frequency coils ( 18 ). A sequence generator ( 60, 62, 64, 66 ) generates an anti-ghosting imaging sequence by dividing k-space into a plurality of profile sub-sets. The sequence generator ( 60, 62, 64, 66 ) includes a profile sub-sets ordering processor ( 60, 62, 64 ) that orders profiles within each profile sub-set such that the order of profiles within each sub-set is generally different from the orders of the other profile sub-sets, and a profile sub-sets acquisition ordering processor ( 60, 66 ) that orders the profile sub-sets in accordance with a selected long-term profiles ordering. The magnetic resonance imaging scanner ( 10 ) executes the anti-ghosting imaging sequence to generate imaging data. A reconstruction processor ( 44 ) reconstructs the generated imaging data into a reconstructed image substantially free of ghosting.
