Persistent long-term subclinical myocardial changes in multisystem inflammatory syndrome in children revealed by cardiac magnetic resonance and galectin-3

Figure 1 Cardiac magnetic resonance imaging short-axis views at mid-ventricular level in a representative patient at follow-up. A: Late gadolinium enhancement image showing no myocardial enhancement; B: T2 parametric map demonstrating normal myocardial T2 values, indicating the absence of active myocardial edema; C: Native T1 parametric map demonstrating elevated T1 values, suggesting diffuse myocardial changes. These findings illustrate subclinical myocardial abnormalities detected on cardiac magnetic resonance imaging despite normal echocardiographic findings.
