Native T1 mean value (A–C) and standard deviation of native T1 (D–F) for each of the six myocardial segments in the base (A, D), mid-ventricle (B, E), and apex (C, F) slices across all patients (n = 47). *P < 0.05, **P < 0.01, ****P < 0.0001 vs. IS or I, assessed by one-way ANOVA followed by Tukey’s test. A, anterior; AS, anteroseptal; IS, inferoseptal; I, inferior; IL, inferolateral; AL, anterolateral.
