Abstract
A method for generating an MR image of an object situated in an examination volume of an MR apparatus begins with the acquisition of a plurality of echo signals having at least two different echo-time values (t1, t2, t3). The echo signals are generated from high-frequency pulses and magnetic-field gradient pulses by an imaging sequence. An intermediate MR image (5, 6, 7) is then reconstructed for each echo-time value (t1, t2, t3). By analyzing these intermediate MR images (5, 6, 7), local relaxation times (T2*(x)) and/or local frequency shifts (.DELTA..omega.(x)) are determined by taking account of the respective echo-time values (t1, t2, t3). Finally, a definitive MR image (11) is reconstructed from the echo signals (1) in their entirety.
