Figure 4 Midventricular End-Systolic Magnetic Resonance Images of a WT Mouse Heart 1 Day After MI

(A) Black-blood cine image clearly delineates the left ventricular chamber at the endocardial border. (B) Delayed contrast-enhanced image highlights the transmurally infarcted myocardium extending from 10 to 5 o’clock. (C) Myocardial tagging reveals lack of tag deformation in contrast-enhanced zones (B) and preservation of contraction in remote myocardium. Abbreviations as in Figure 2.
