T2-mapping in acute apical infarction. The diastolic cine frame (A) reveals apical septal wall thickening in the area of edema. Late gadolinium enhancement shows apical infarction scar with microvascular obstruction (B). While conventional T2-weighted STIR image depicts both, edema and bright slow flowing blood within the lumen (C), T2 map correctly indicates edema color-coded in orange with an apical T2 of 91 ms (D). The microvascular obstruction corresponds to a T2 of 60 ms, color-coded in pink. Basal T2 was 54 ms.
