摘要

The present invention relates to a method for analysing an object by means of nuclear magnetic resonance imaging. The method comprising - issuing a pulse sequence (1) to an NMR apparatus, the pulse sequence (1) comprising a plurality of acquisition phases (3); - within a respective acquisition phase (3), acquiring a corresponding set of imaging data; and - quantifying at least one contrast parameter of the object based on the acquired sets of imaging data and simulated data; wherein the acquisition phase (3) comprises the following steps in the given order: - an excitation step (5) for flipping a longitudinal magnetization of one or more nuclear spins in the object into a transversal plane by a variable flip-angle, thereby inducing a transversal magnetization; - an image readout step (6) for reading out the corresponding set of imaging data; and - a spoiling step (7) for depleting the transversal magnetization; wherein a timing of the steps and/or the flip-angle is varied between at least two of the plurality of acquisition phases (3). Further, the present invention relates to a corresponding computer program product, a control apparatus for NMR and to a nuclear magnetic resonance apparatus.
