Myocardial inflammation

Overview
Myocardial inflammation associated with myocarditis appears as a high intensity signal with delayed gadolinium hyperenhancement on cardiac MRI (cMRI). . While the cMRI pattern of gadolinium hyperenhancement in ST segment elevation myocardial infarction is transmural and extends from the endocardium to the epicardium, the patchy, non-segmental hyperenhancement pattern in myocarditis in contrast involves the epicardium and spares the subendocardium.
