Cardiovascular magnetic resonance imaging assessment of myocardial viability and infarction using late gadolinium enhancement (LGE). (A) LGE image in a mid short-axis location showing homogenous signal in all segments with no evidence of myocardial infarction. (B) LGE image in short-axis orientation showing subendocardial infarction (25–50% transmural extent) in the inferior wall. (C) LGE image in short-axis orientation showing myocardial infarction involving 50–75% of wall thickness in the lateral wall. (D) LGE image in short-axis orientation showing transmural infarction in the lateral wall (white arrow).
