Figure 5.

Representative cases. Fusion of polar plots from MPS acquired acutely and LGE images acquired one week after the acute MI in two patients subjected to ischemia for 110 and 190 minutes, respectively. The MPS polar plots indicate MaR (black) in the otherwise well perfused myocardium (yellow). The center of the polar plot represents the left ventricular apex and the periphery represents the basal parts of the left ventricle. Final MI size by LGE is shown in white, where brightness indicates MI transmurality from 0% (black) to 100% (white). LGE = late gadolinium enhancement; LV = left ventricle; MaR = myocardium at risk.
