Reperfusion injury components and manifestations determined by cardiovascular MR and MDCT imaging

Figure 1 Multi-slice T2-weighted turbo spin echo imaging demonstrates the hyperintense edematous area at risk (white arrows in the left images) with hypoenhanced zone, which may represent microvascular and/or interstitial hemorrhage zone (arrowhead in the left images). Delayed contrast enhancement magnetic resonance (DE-MR) imaging confirmed the presence of microvascular and/or interstitial hemorrhage zone in the core (black arrowhead in the right images) of hyperenhanced infarcted myocardium (black arrows in the right images).
