Calculated excitation patterns for velocity-selective excitation, relative to conventional single-pulse excitation. (a) effective excitation patterns for various encoding strengths inside the LV blood pool. Encoding of higher velocities yields a wider suppression band around the nominal values. (b) zoomed-in view for velocity range typically observed inside the myocardium (red box, a). For encoding strengths >30 cm/s the myocardial signal is hardly affected (<10%). (c) echo-time prolongation for velocity-selective excitation with respect to conventional single-pulse excitation for various encoding strengths
