We implemented and validated a MRF sequence for simultaneous T₁ and T₂* quantification in the kidneys covering 4 slices within one breath-hold. Therefore, we used an echo-planar-imaging readout with fully sampled k-space and 35 measuremets for the matching process. We achieved promising results in phantom and in 8 healthy volunteers compared with conventional methods as MOLLI and GRE and with reference scans. Additionally, we performed smoothing on the baseline images to further improve the image qualitiy of the MRF parametric maps.
