Claim:
1. A method to acquire magnetic resonance (MR) data from a volume segment of a subject situated in an MR data acquisition unit, comprising: operating the MR data acquisition unit to repeatedly, in a plurality of repetitions, expose the subject situated in the MR data acquisition unit to an MR data acquisition sequence; in each repetition of said sequence, operating the MR data acquisition unit to radiate a first resonant radio-frequency (RF) pulse, radiate a second resonant RF pulse after radiating said first resonant RF pulse, apply a dephasing first gradient after radiating the first resonant RF pulse and before radiating the second resonant RF pulse, radiate a third resonant RF pulse after radiating the second resonant RF pulse, apply a second gradient after radiating the third RF resonant pulse, that refocuses a stimulated echo of a magnetization component in the subject prepared by the dephasing first gradient, and reading out MR data associated with the stimulated echo; operating said MR data acquisition unit with a dissimilarity between a respective repetition, among said plurality of repetitions, and a next-successive repetition that directly follows said respective repetition, said dissimilarity being selected from the group consisting of (i) said first gradient in said respective repetition differing from said first gradient in said next-successive repetition, (ii) said second gradient in said respective repetition differing from said second gradient in said next-successive repetition, and (iii) both (i) and (ii); and in a processor, collecting all MR data read out in said plurality of repetitions in a data file, and making said data file available in electronic form at an output of the processor.
