Abstract
A method for imaging a subject using an MRI system includes determining a plurality of echo times and then acquiring a plurality of variable echo time signals corresponding to the plurality of echo times at a plurality of k-space locations. In the method, a water k-space data signal and a fat k-space data signal is generated for each of the plurality of k-space locations based on the plurality of variable echo time signals corresponding to that k-space location. Finally, the method includes generating a medical image of the subject based on water k-space data signals and fat k-space data signals at the plurality of k-space locations respectively.

A method for imaging a subject using an magnetic resonance imaging (MRI) system comprising:
- determining a plurality of echo times;
- acquiring a plurality of variable echo time signals corresponding to the plurality of echo times at each of a plurality of k-space locations;
- generating a water k-space data signal and a fat k-space data signal for each of the plurality of k-space locations based on the plurality of variable echo time signals corresponding to that k-space location;
- and
- generating a medical image of the subject based on water k-space data signals and fat k-space data signals at the plurality of k-space locations respectively.
A magnetic resonance imaging (MRI) system, comprising:
- a magnet configured to generate a polarizing magnetic field about at least a portion of a subject arranged in the MRI system;
- a gradient coil assembly including a readout gradient coil, a phase gradient coil, a slice selection gradient coil configured to apply at least one gradient field to the polarizing magnetic field;
