ABSTRACT:
An MR method and apparatus determines spatially resolved relaxation parameters of a subject in an examination zone, voxel by voxel. A first MR scan sequence is applied to generate a series of first MR data sets having different echo times. A second MR scan sequence is applied to generate at least one further MR data set having an enhanced spatial resolution and reduced time resolution in comparison with the first MR data sets from the first sequence. MR combination images are generated using the first MR data sets derived from the first sequence for a portion within the k-space and the further MR data set acquired outside this portion by the second sequence. The relaxation parameters are determined from the MR combination images.
