From: Understanding why edema in salvaged myocardium is difficult to detect by late gadolinium enhancement
A representative short-axis slice from a dog that has undergone coronary occlusion and reperfusion. Blood pool, remote myocardium, infarcted myocardium and salvaged myocardium are delineated in the respective images. Note how salvaged myocardium is hypointense on LGE (indicating no infarction), hyperintense on T2-prepared SSFP (indicating edema), has an increased pre-gadolinium T1, barely perceivable reduced post-gadolinium T1, and an increased extracellular volume fraction (ECV). The blood pool of the ECV image has been set to black for clarity.
