A new method for motion correction of T2*-weighted data and resulting quantitative T2* maps is presented. For this method, additional data sets with a reduced number of phase encoding steps covering the k-space centre are acquired. Motion correction is based on a 3-step procedure: (1) calculation of improved input data sets with reduced artefact levels from the original data, (2) creation of a target...
Numerous clinical and research applications for quantitative mapping of the effective transverse relaxation time T*2 have been described. Subject motion can severely deteriorate the quality and accuracy of results. A correction method for T*2 maps acquired with multi‐slice multiple gradient echo FLASH imaging is presented, based on acquisition repetition with reduced spatial resolution (and consequently...
