Non-fulminant acute myocarditis in a 44-year-old man presenting with sudden occurrence of signs and symptoms of heart failure (New York Heart Association [NYHA] class III). Cine-SSFP four-chamber end-diastolic frame shows a mildly dilated left ventricular cavity (EDV 187Â mL) with significant right-sided pleural effusion; ejection fraction is mildly depressed (44Â %). Typical subepicardial striae of high signal intensity are located at the level of the mid-inferior left ventricle on both T2w-STIR (b) and LGE images (c). Native (d) and post-contrast (e) T1 mapping scans were also performed using a modified Look-Locker inversion recovery (MOLLI) sequence with a 1.5Â T scanner (MAGNETOM Avanto; Siemens Healthcare, Erlangen, Germany), showing abnormally elevated extracellular volume within the mid-inferior segment (36.7Â %).
