A number of repetitions of a magnetic resonance measurement sequence and a number of repetitions of a navigator magnetic resonance measurement sequence are executed in a interleaved manner. Each repetition of the magnetic resonance measurement sequence includes the time-parallel creation of gradient echoes for measurement of magnetic resonance data. Each repetition of the navigator magnetic resonance measurement sequence includes the radiating of RF excitation pulse, the activation of at least one gradient pulse train for time-sequential creation of gradient echoes, and the read out of the gradient echoes as navigator magnetic resonance data. The magnetic resonance data are modified based on the navigator magnetic resonance data. This enables an N/2 ghosting artifact and/or a constant magnetic field drift and/or a movement artifact to be reduced. Such techniques can be applied in conjunction with simultaneous multi-slice echo planar magnetic resonance imaging, SMS EPI. Diffusion-weighted magnetic resonance imaging also is possible.
