<p>PROBLEM TO BE SOLVED: To provide a magnetic resonance measurement method that enable a relatively precise determination of spectral components and that require only a small number of MR signals at different echo times, so as to ensure a relatively short measurement duration.SOLUTION: A predetermined spectral model of a multipoint Dixon technique includes at least two spectral components with respective associated relaxation rates, a first phase due to field inhomogeneities, and a second phase due to eddy current effects. MR data 25 is acquired using a bipolar multiecho magnetic resonance measurement sequence 5 for plural pixels. For each pixel, the multiecho magnetic resonance measurement sequence 5 alternately uses positive and negative readout gradient fields 16-1, 16-2, 16-3 for the readout of MR signals of the MR data in at least three echo times 21, 22, 23. The at least two spectral components are determined based on the MR data 25.</p> |
