Results of the in vivo measurements at low Trec variability. The recovery times recorded during the data acquisition are shown in A. The different colored curves show the individual Trec times for 10 repetitions of the T1ρ mapping sequence in animal II. In B the calculated relaxation time maps (short axis view, isotropic resolution 250 µm) for the monoexponential fit (left) and the corrected fit (right) are shown. 5 repetitions with different Trec times are exemplary shown. The mean T1 value 1342 ± 44 ms in myocardial tissue was obtained by an IRSF sequence and used to calculate the corrected maps. A high image quality and less streaking is perceptible due to reduced motion issues. The ROI based correlation analysis with Trec is shown in Fig. 6B
