| Zusammenfassung | In this work, a Fourier-based technique for 1H MR spectroscopy based on split-slice-GRAPPA is introduced to decompose simultaneously acquired dual-voxel data. In contrast to the existing sensitivity-map-based approach, this technique does not need any additional image acquisitions. The autocalibration lines are derived by additional low-resolution spectral data. 2SPECIAL was used to simultaneously acquire data from two voxels at short echo times. The proposed decomposition algorithm was first validated in a multi-compartment phantom, and its application was then demonstrated at 7T in vivo. |
