Cardiac magnetic resonance. The left side of the panel on the left shows the diffuse subendocardial late gadolinium enhancement pattern in the absence of a coronary pattern distribution in short axis images. The right side of the panel on the left shows the absence of oedema. From top to bottom: basal segments, mid segments and apical segments. The panel on the right reports the four-chamber delayed enhancement image showing the diffuse subendocardial enhancement, the atrial enhancement, and the limited apical necrosis.
