| 摘要 |
The invention relates to a method of imaging at least two chemical species using magnetic resonance imaging with signal separation for the two chemical species, the method comprising:-acquiring first and second echo data at different echo times resulting in a first and second acquired complex dataset,-modelling the first and second acquired dataset, said modelling comprising a spectral signal model of at least one of the chemical species,-identifying in the first and second acquired dataset the voxels for which the modelling yields a single, unambiguous mathematical solution for the signal separation, and-resolving the ambiguity for the voxels for which the modelling yields more than one mathematical solution, if any such voxels remain. |
