Keywords: Quantitative Imaging, RelaxometryIn this study, we used a method for fast in vivo T1 and T2* mapping of fast relaxing tissues of the knee using a high resolution 3D spoiled gradient ultrashort echo time research application sequence with spiral read out to quantitatively describe different tissues. We manually segmented 10 different tissues in five healthy young volunteers and found good agreement with literature values for fast relaxing tissues. The bivariate histograms showed tissue specific clusters, which can be used for tissue differentiation. Additional information, such as phase images, could further improve bivariate histogram-based tissue differentiation and should be explored in future studies.
