Contrast-enhanced MRI to recognize myocarditis with STEMI presentation

Myocarditis is difficult to recognize in the early phase particularly when it mimics acute myocardial infarction (STEMI). New strategies to diagnose active myocarditis are needed to avoid unnecessary coronary angiography in such an acute setting. Contrast-enhanced magnetic resonance imaging (MRI) is able to discriminate the small myocardial injuries due to myocarditis from the segmental lesions of ischemic origin.
