T1-Based Criteria for Myocarditis on Cardiac MRI in Patients With Recent COVID-19 mRNA Vaccination

Caption

Early gadolinium enhancement (EGE) compared with precontrast SSFP sequence (not shown) is observed on early postcontrast short-axis SSFP images in (A) 16-year-old male, (B) 17-year-old male, (C) 16-year-old male, and (D) 19-year-old male, and on early postcontrast short-axis perfusion image in (E) 17-year-old male (arrow, A-E). Late gadolinium enhancement (LGE) is also present (arrows) in all 5 patients (F, G, H, I, and J; same patients as in A, B, C, D, and E, respectively). EGE and LGE predominantly affect subepicardium of the inferior, inferolateral, or anterolateral walls. EGE extends beyond confines of LGE in patient shown in (A) and (F) and in (B) and (G). Basilar LV involvement is present in patient shown in (A) and (F), (B) and (G), and (C) and (H). Mid-cavity LV involvement is present in patient shown in (D) and (I) and in (E) and (J).
