Claim 0:
1. A method for correcting chemical shift artifacts (CSA) arising in a DIXON magnetic resonance (MR) method when using bipolar readout gradients (fast DIXON MR) to capture in-phase and opposed-phase echoes, the method comprising:
providing a trained convolutional neural network (CNN), which has been trained using acquisition data acquired in phase and in opposed phase by the DIXON MR method, comprising acquisition data that contains CSA in mutually opposite directions, and acquisition data that contains CSA only in one direction, so that the CNN is trained to transform acquisition data obtained by the fast DIXON MR method such that the acquisition data acquired by the fast DIXON MR method exhibits CSA that arise only in the same direction;
acquiring fast DIXON MR acquisition data using respective control instructions; and
applying the trained CNN to the acquisition data acquired using the respective control instructions to minimize or entirely remove the CSA and to calculate corrected acquisition data.
