Cardiac magnetic resonance imaging demonstrating imaging features consistent with myocarditis for Patient 2. Late gadolinium enhancement (LGE) % of left ventricular mass = 19%. (A) Short-axis oblique late gadolinium enhancement demonstrating epicardial hyper-intense signal in the infero-lateral wall (white arrows). (B) Four-chamber late gadolinium enhancement demonstrating epicardial hyper-intense signal in the lateral wall (white arrows). (C) Native T₁ map demonstrating increased T₁ values in the lateral and inferior segments with values up to 1400 ms (normal values in this 3T scanner 1200 ± 50 ms).
