Abstract: In a magnetic resonance (MR) method and apparatus, an image reconstruction algorithm is used to reconstruct image data from k-space data that represent an acquired MR signal, and the reconstruction algorithm makes use of a model that requires the MR signal to exhibit a signal behavior from a relaxation model. In order to permit the reconstruction algorithm to be used when the acquired MR signal does not exhibit the model signal behavior due to motion of the subject, the k-space data are motion-corrected so as to produce corrected k-space data that represent said model signal behavior, and image data are reconstructed from the corrected k-space data using the reconstruction algorithm.
