Claim Text:
1. A method of magnetic resonance spectroscopic imaging of an object, said object including at least one chemical species to be imaged, which chemical species has magnetic resonance signals of nuclei with a magnetogyric ratio γ A within a specific spectral bandwidth, said method comprising the steps of: arranging the object in a stationary magnetic field; subjecting the object to a plurality of first sampling sequences with an excitation sequence and an encoding sequence of phase-encoding and read-out gradients resulting in a sampling of a plurality of k-space segments of the k-space and covering the k-space in an interleaved fashion, such that a plurality of N 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 reconstructing a spectrally resolved image of the object based on the collected gradient-echo signals, wherein a flyback gradient pulse is used for rewinding the k-space trajectories after reaching the k-space border and before starting a next k-space trajectory of a subsequent spectral dwell time from an intended position in k-space.
