1. A method for magnetic resonance imaging, wherein an imaging volume is subjected to at least one sequence of resonance frequency (RF) pulses and gradient magnetic field pulses (gradients), each RF pulse of the at least one sequence is applied in a presence of a gradient, the method comprising, in the at least one sequence:

  • applying at least one first excitation RF pulse within at least one first excitation resonance-frequency range in order to excite transverse magnetization within at least one first slice location within the imaging volume and in order to form at least one first echo signal from the first slice location;

    applying at least one second excitation RF pulse within at least one second excitation resonance-frequency range in order to excite transverse magnetization within at least one second slice location within the imaging volume, the at least one second slice location is distinguished from the at least one first slice location, and in order to form, prior to the at least one first echo signal, at least one second echo signal from the at least one second slice location; and

    acquiring the at least one first and the at least one second echo signals in order to form a corrected data set,wherein, of the at least one first and the at least one second echo signals, at least one echo signal is formed with phase encoding, at least another echo signal is at least one reference echo signal;

    at least one phase shift of the at least one reference echo signal is at least one reference phase shift, a motion-related phase shift of the at least one echo signal is compensated based on the at least one reference phase shift.
