Fig. 1: Results of cardiovascular MRI with delayed contrast enhancement in myocardial infarction (MI). A and B: Four-chamber and 2-chamber views, respectively, of acute (48-hour) transmural anterior MI with areas of microvascular obstruction (black arrowhead) surrounded by bright signal (white arrowhead), the “halo sign,” and apical thrombus (black arrow). C and D: Two-chamber and short-axis views, respectively, of old MI limited to the subendocardial region of the basal inferolateral wall (arrows). LA = left atrium, LV = left ventricle, RV = right ventricle.
