| Zusammenfassung | In this work we investigate the impact of intra-voxel dephasing on standard FISP-MRF measurements and propose the use of a constant TR to improve the robustness against spatially changing magnetic fields. The results have shown that FISP-MRF measurements with a variable TR are susceptible to intra-voxel dephasing, which may generate temporal signal modulations that are likely to cause quantification errors in relaxation parameters. This can be alleviated by fixing TR without loss of encoding capability. |
