System and method for water, fat, and field inhomogeneity magnetic resonance imaging from single magnetic resonance image acquisition

A system for generating magnetic resonance images, comprising:

• a memory encoding processor-executable routines;
• a processing system comprising one or more processors and configured to access the memory and to execute the processor-executable routines, wherein the processor-executable routines, when executed by the processing system, cause the processing system to:
• obtain a single complex magnetic resonance image per slice from magnetic resonance scan data acquired of a subject with a magnetic resonance scanner utilizing a Dixon sequence where signal contributions from water and fat to acquired echo signals are separated, wherein the single complex magnetic resonance image comprises a non-zero phase angle between the water and the fat;
• input the single complex magnetic resonance image for each slice into a decomposition model trained to predict Dixon-like images from the single complex magnetic resonance image for each slice;
• and
• output from the decomposition model a water image, a fat image, and a field inhomogeneity image based on the single complex magnetic resonance image for each slice.

A non-transitory computer-readable medium, the computer-readable medium comprising processor-executable code that when executed by a processing system comprising one or more processors, causes the processing system to:

• obtain a single complex magnetic resonance image per slice from magnetic resonance scan data acquired of a subject with a magnetic resonance scanner utilizing a Dixon sequence where signal contributions from water and fat to acquired echo signals are separated, wherein the single complex magnetic resonance image comprises a non-zero phase angle between the water and the fat;
• input the single complex magnetic resonance image for each slice into a decomposition model trained to predict Dixon-like images from the single complex magnetic resonance image for each slice;
• and
• output from the decomposition model a water image, a fat image, and a field inhomogeneity image based on the single complex magnetic resonance image for each slice.
