Border sharpness of scar tissue after myocardial infarction as determined by self-navigated free-breathing isotropic 3D whole-heart inversion recovery magnetic resonance

Table 1 Border sharpness of 2D LGE and 3DSN-IR images. Border sharpness of "blood pool to non-infarcted myocardium"," blood pool to scar" and "non-infarcted myocardium to scar" in mm-1. Data are mean ± standard deviation or range (interquartile) where appropriate.
