Acute myocarditis


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 Gd (late Gd enhancement-LGE ) can visualize irreversible injury (necrosis in the acute setting and scar at a chronic stage) as areas with high signal intensity.
