Evolution of T2 value of myocardial edema in G1 and G2 over time. There is a tendency for higher T2 values in G2, compared with those in G1. T2 value or myocardial edema peaks at 48j in G2, whereas it peaks at 24 h in G1.
G1: myocardial infarction without intramyocardial hemorrhage
G2: myocardial infarction with intramyocardial hemorrhage.
