Focal transmural edema of the myocardium (20 mm) in the inferior medial segment of the left ventricle. No pericardial effusion.

T1WI: No signal alteration

T2WI: High signal in the inferior medial segment of the LV

T2 fat sat: High signal in the inferior medial segment of the LV

LGE: Transmural focal LGE in the inferior medial segment of the LV

Case Discussion

Suspected myocarditis is one of the most frequent indications for cardiac MRI and the only imaging modality that allows for assessing myocardial edema. The use of contrast agent-sensitive sequences acquired ≥10 minutes after injection of Gadolinium (LGE = late Gd enhancement) can visualize irreversible injury (necrosis in the acute setting and scar at a chronic stage) as areas with high signal intensity.
