Bland Altman analysis of the apical angle (ApA), wall thickness (WT) of segment 2, and wall thickness for segment 13 for intra- and inter-observer variability in this cohort. Variability of intra-observer (a) and inter-observer (b) for ApA, intra-observer (c) and inter-observer (d) for segment 2 wall thickness, and intra-observer (e) and inter-observer (f) for segment 13 are shown. The middle-dashed line indicates the mean difference and gray area between dash lines indicates the standard deviation
