1. A magnetic resonance (MR) system for generating a map, said system comprising: a MR scanner defining an examination volume; and, at least one processor programmed to: control the MR scanner to apply imaging sequences to the examination volume; in response to the imagine sequences, receive MR data sets of the examination volume wherein the MR data sets include MR phase data of a series of echo time (TE) acquisitions; identify change in phase over time of the MR phase data to identify different tissue and/or material types found in pixels car voxels of the map; and assign one or more tissue-specific and/or material-specific values to each pixel or voxel of the map based on the tissue and/or material type(s) identified as being in each pixel or voxel during the analysis of the MR data sets.
