In a method and apparatus for magnetic resonance data acquisition, data are acquired according to a single-slab three-dimensional turbo or fast spin-echo pulse sequence, wherein the inner volume selection in the phase-encoding direction takes place by radiating a pair of adiabatic RF pulses, instead of the single refocusing RF pulse that is conventional. The radiation of the adiabatic RF pulses allows a high RF pulse bandwidth to be achieved, for a given limit on the peak radio-frequency field strength. Such a high RF pulse bandwidth reduces off-resonance-related artifacts.
