A method for magnetic resonance imaging (MRI) includes performing an echo planar imaging acquisition using inverted up/down phase encoding directions and reconstructing acquired images having geometric distortions along the phase encoding directions due to off-resonant spins; feed-forward estimating by a convolutional neural network (CNN) a phase distortion map from the acquired images; where the CNN is trained to minimize a similarity metric between un-warped up/down image pairs; and performing geometric distortion correction of the acquired images using the phase distortion map to unwarp the acquired images.
