In a method and magnetic resonance (MR) apparatus to acquire MR data in a predetermined three-dimensional volume segment of an examination subject, the three-dimensional volume segment is selectively excited with an RF excitation pulse, wherein a magnetic field gradient at the same time is switched. Two phase coding gradients and an additional magnetic field gradient are switched for spatial coding and MR data are acquired depending on this. A frequency range of the RF excitation pulse is set depending on resonance frequencies of at least two substances to be acquired within the volume segment, such that a center frequency of the frequency range is caused to be located between the resonance frequencies. |
