  Figure 1. Case 1: Cardiac Magnetic Resonance and Positron Emission Tomography Images Late gadolinium enhancement (LGE) imaging on cardiac magnetic resonance in the (A) short-axis, (B) 4-chamber, and (C) 3-chamber views demonstrating focal LGE along the anterior and inferior right ventricular insertion sites as well as faint midwall LGE along the septal segments. (D) Positron emission tomography imaging demonstrating focal 18F-fluorodeoxyglucose (FDG) uptake along the lateral and septal segments (odd rows) with normal perfusion (even rows) indicating active inflammation.

  Figure 2. Case 2: Cardiac Magnetic Resonance and Positron Emission Tomography Images LGE imaging on cardiac magnetic resonance in the (A) short-axis, (B) 4-chamber, and (C) 3-chamber views demonstrating extensive LGE along the septal, lateral, and inferior segments. (D) Positron emission tomography imaging demonstrating diffuse FDG uptake throughout the myocardium (odd rows) with normal perfusion (even rows) initially suggesting poor myocardial suppression. Abbreviations as in Figure 1.

  Figure 3. Case 3: Cardiac Magnetic Resonance and Positron Emission Tomography Images LGE imaging on cardiac magnetic resonance in the (A, B) short-axis and (C) 4-chamber views demonstrating extensive LGE along the septal segments as well as subepicardial LGE along the distal lateral segment. (D) Positron emission tomography imaging demonstrating focal FDG uptake along the apical septal segment (odd rows) consistent with active inflammation. Abbreviations as in Figure 1.

  Figure 4. Case 4: Cardiac Magnetic Resonance and Positron Emission Tomography Images LGE imaging on cardiac magnetic resonance in the (A, B) short-axis and (C) 4-chamber views demonstrating extensive midwall LGE along the septal segments as well as subendocardial LGE along the basal inferolateral segments. (D) Positron emission tomography imaging demonstrating focal FDG uptake along the inferolateral segments (odd rows) consistent with active inflammation. Abbreviations as in Figure 1.
