Abstract
A magnetic resonance imaging (“MRI”) system and method for producing an image of a subject with the MRI system in which signal contributions of water and fat are separated are provided. A plurality of in-phase echoes formed at a plurality of different echo times are sampled to acquire k-space data. The in-phase echoes include signal contributions from water and fat that are in-phase with each other. The signal contributions from water and fat are then separated by fitting only those echo signals that are in-phase echo signals to a signal model that models a fat spectrum as including multiple resonance peaks. From these signal contributions, an image of the subject depicting a desired amount of signal contribution from water and a desired amount of signal contribution is produced.
