Fig. 4.

Scar-to-blood contrast-to-noise ratios (CNRs) with their associated elapsed time after contrast agent (CA) injection. The dots indicate ventricular (LV) blood nulling, while the triangles indicate viable myocardium nulling. For each subject, a straight line connects the two observations. Note that a dotted line indicates that viable myocardium nulling was performed first, while a solid line indicated that LV blood nulling was performed first
