Abstract:
1. An MR method for generating an MR image of an object situated in an examination volume of an MR apparatus, which method has the following steps: a) acquisition of a plurality of echo signals having at least two different echo-time values, the echo signals being generated from high-frequency pulses and magnetic-field gradient pulses by means of an imaging sequence, the acquisition of the echo signals takes place by non-Cartesian, and in particular radial, sampling of the spatial frequency space associated with the examination volume; b) reconstruction from the corresponding echo signals of one intermediate MR image for each echo-time value; c) determination of local relaxation times and/or local frequency shifts by analyzing the intermediate MR images while taking account of the respective echo-time values; d) reconstruction of a definitive MR image from the echo signals in their entirety.
