Cross terms of background gradients with diffusion gradients often hamper the accurate determination of diffusion coefficients in MR experiments, in particular if microscopic background gradients are present which vary within a voxel. For diffusion weighting based on a stimulated echo preparation several approaches that inherently null these cross terms have been presented in the past. The generalized MAGSTE technique is the most appropriate for echo-planar imaging acquisitions because it takes long fill time contributions of the echo train into account. Here, an extension of the generalized MAGSTE technique is presented that increases the diffusion-weighting efficiency without sacrificing the cross-term compensation.
