Abstract

The invention is directed to a method to determine a susceptibility distribution (40) of an examination subject, the method comprising the steps: (a) receiving an MR image dataset (23) acquired during an examination session from a recoding region (68) covering a part of the body of the examination subject and having a first resolution (Δx), (b) segmenting the MR image dataset (23) into regions depicting air (61) and regions depicting biological tissue (62, 63) and assigning a pre-determined susceptibility value to each segmented region, c) applying a trained function based on at least one neural network (50, 52, 54, 56) to the MR image dataset (23) or the segmented MR image dataset (33) as input data, wherein the trained function generates as output data an output image (40) having a higher resolution (Δw) than the MR image dataset or the segmented MR image dataset and/or covering an output region (68) which is larger than the recording region of the MR image dataset (23), d) providing a susceptibility distribution (40) of the output region (68) which is based on the output image.
