A magnetic resonance imaging (MRI) system, method and/or computer readable medium is configured to effect MR imaging with reduced artifact by generating one or more image reconstruction maps from one or more prescans, acquiring a main scan dataset from a main MRI scan of an object, warping one or more image reconstruction maps to have geometric distortions substantially corresponding to geometric distortions in the main scan dataset, and forming a diagnostic MR image of the object using the main scan dataset and the warped one or more image reconstruction maps.
