Extracellular volume (ECV) calculated from T1 maps can quantitatively characterize myocardial tissue, including the severity of tissue damage in myocardial infarction (MI) (1). An alternative approach for measuring the density of MI may be to calculate the relative signal intensity of LGE images.) A direct comparison of signal intensity of LGE and ECV in MI has not been carried out. We aimed to compare these two parameters in patients presenting with acute myocardial infarction.
Signal intensity of LGE in patients presenting with acute-MI is not correlated to the ECV in the infarct zone or to the relative ECV. ECV mapping is required to quantify the extent of tissue injury in acute MI.
