Figure 7

Bland Altman plots of point-wise and sector-wise comparison of fully sampled and retrospectively undersampled in-vivo data (R = 3 and 4) in healthy volunteers. Mean differences (grey) and 95% levels of agreement (2SD) (black) are indicated by the dashed lines. Analysis was performed on the entire LV. Point-wise comparison was performed for the polar coordinates r (a, c) and ϕ (b, d) for each tracked point. Circumferential shortening (e, g) and rotation (f, h) were compared per sector.
