    摘要： A method of magnetic resonance spectroscopic imaging of an object (O) including at least one chemical species to be imaged, comprising sampling of the
    k -space such that a plurality of
    N
    ω first sampling trajectories through at least one
    k -space segment of the
    k -space is formed along a phase-encoding direction, each of said first sampling trajectories beginning in a central
    k -space region and continuing to a
    k -space border of the at least one
    k -space segment and having a duration equal to or below a spectral dwell time corresponding to the reciprocal spectral bandwidth, collecting at least one first set of gradient-echo signals obtained along said first sampling trajectories, collecting at least one second set of gradient-echo signals obtained along a plurality of
    N
    ω second sampling trajectories, said
    N
    ω second sampling trajectories and said
    N
    ω first sampling trajectories being mutually mirrored relative to a predetermined
    k -space line in the central
    k -space region.

    摘要： In a magnetic resonance method, a localizing magnetic field gradient (GL) is determined suitable for acquiring a first resonant species magnetic resonance localized to a first sampling region (Rm1). A second sampling region (Rm2) defined by the localizing magnetic field gradient for a second resonant species magnetic resonance is determined. The second sampling region is spatially shifted from the first sampling region due to different gyromagnetic ratios of the first and second resonant species magnetic resonances. At least the second sampling region is displayed together with an image (62) of a subject disposed in the main magnetic field.
