Dice similarity coefficient (DSC) (a,b) and myocardial boundary error (MBE) (c,d) obtained using the T2P4TE sequence under breath-hold (BH), free breathing (FB), and free breathing with respiratory navigator gating (FB + NAV). DSCs and MBEs of all T2-weighted images are shown in (a) and (b), respectively. (b) and (d) show DSC and MBE as average (central dot), standard deviation (box size) and minimum/maximum (whiskers) over all subjects and all T2-weighted images (except the T2prep = ∞ images). In-plane motion correction improves the DSC and reduces the MBE for all cases. Furthermore, motion corrected DSC and MBE were similar for all 3 acquisitions (i.e. BH, FB, FB + NAV)
