Reproducibility of T2 mapping using the T2P20TE sequence acquired under free breathing with respiratory navigator gating. Reproducibility was evaluated for T2 maps reconstructed using only a subset of the T2prep echo times (0 ms, 25 ms, 50 ms, ∞) (4TEs) (a,b) and using all 20 T2prep echo times (20 TEs) (c,d). Average and standard deviation of T2 reproducibility is reported over all subjects for each segment (a,c) and over all segments for each subject (b,d). In-plane motion correction using ARCTIC improves the reproducibility of T2 mapping
