Abstract:
1. A method for producing an image of a subject with a magnetic resonance imaging (MRI) system, the steps of the method comprising: a) acquiring from the subject with the MRI system, a plurality of image data sets by sampling k-space along trajectories at a corresponding plurality of echo times that occur during a plurality of repetition time periods, in which odd-numbered ones of the plurality of image data sets are acquired at odd-numbered ones of the corresponding plurality of echo times occurring during odd-numbered ones of the plurality of repetition time periods and even-numbered ones of the plurality of image data sets are acquired at even-numbered ones of the corresponding plurality of echo times occurring during even-numbered ones of the plurality of repetition time periods; b) reconstructing from the plurality of image data sets acquired in step a), a plurality of images depicting the subject; c) calculating respective signal contributions from at least two chemical species using the plurality of images reconstructed in step b); and d) producing an image that depicts signal contributions from substantially only one of the at least two chemical species using the respective signal contribution calculated in step c).
