Cardiovascular magnetic resonance imaging in myocarditis.

Cardiovascular magnetic resonance imaging (CMR) has become the leading modality in noninvasive imaging of myocarditis. Consensus on the use of 3 CMR criteria for myocarditis, referred to as edema, early, and late enhancement, has standardized CMR protocol for assessing myocarditis. Although definite diagnosis of myocarditis remains challenging, the outcome of this disease necessitates further investigation with the objective of providing robust noninvasive tests. Moreover, relative to current tools such as endomyocardial biopsy, CMR is a promising technique in the setting of this insidious and complex disease.
