1. A method for reordering k-space data acquired with a segmented MRI pulse sequence, the method comprising:
synchronizing to a physiologic signal of a heart or vessel, to a respiratory signal, or to an external trigger source; and
acquiring a plurality of data collecting segments each as a contiguous block in a phase encoding direction such that lines of the plurality of data collecting segments are alternately acquired in a forward direction, wherein the lines are acquired in order from a first line to last line, and a reverse direction, wherein the lines are acquired in order from the last line to the first line, for each consecutive data collecting segment,
wherein the plurality of data collecting segments covers all k-space locations.
