Abstract:
1. An MR method of determining local relaxation time values of an examination object, comprising the following method steps: a) recording and reconstructing two or more MR images of the examination object, each with different time parameter sets of an imaging sequence; b) recording and reconstructing MR images of a phantom with the same time parameter sets of the imaging sequence, wherein the phantom has a known spatial distribution of relaxation time values; c) determining local relaxation time values of the examination object by comparing image values of the MR images of the examination object with image values of the MR images of the phantom and by assigning image values of the MR images of the phantom to relaxation time values according to the known spatial distribution of relaxation time values of the phantom; and d) displaying at least one of the MR images adjusted based on the determined local relaxation time values.
