Systems and methods are provided for producing diffusion-weighted images of a subject using a magnetic resonance imaging (MRI) system. The method includes performing a stimulated echo preparation module using non-selective radio-frequency (RF) pulses designed to induce a stimulated echo, performing an acquisition module that includes a multi-slice acquisition of MR data in the presence of diffusion gradients, and reconstructing the diffusion-weighted images of the subject from the MR data.

In a method for operating a MR facility for recording a MR dataset using a simultaneous multislice imaging technique, a recording sequence is established using an ordering rule. The recording sequence includes an allocation of slices to corresponding sequence portions of at least one repetition sequence covering all the slices of at least one allocated concatenation. A crosstalk condition for the established recording sequence is evaluated, which checks whether at least one first slice that is recorded in the last sequence portion of a repetition sequence is spatially adjacent to at least one second slice which is recorded in the first sequence portion of the same repetition sequence. The recording sequence may be adapted, based on the crosstalk condition, to increase the temporal separation between the recording of the first and second slices. The adapting may include displacing a slice group to a central sequence portion of the repetition sequence.
