Cardiac magnetic resonance imaging (CMR) became over the last 30 years an essential tool in the management of patients with myocarditis. Noninvasive diagnosis of acute myocarditis relies on a clinical picture compatible with myocarditis and fulfilling of the updated 2018 Lake Louise criteria. These criteria include highlights of myocardial edema by conventional T2-weighted sequences or by T2 mapping in one hand and evidence of myocardial injury using late gadolinium enhancement sequences, T1 mapping or extra-cellular volume measurement in the other hand. It is recommended to perform basal examination in the 2 or 3 weeks following acute episode and to repeat CMR during follow-up. The literature reports excellent diagnostic accuracy, between 80% and 90%, making CMR a robust and reliable noninvasive alternative to endomyocardial biopsy. Besides, beyond its diagnostic performance, CMR can also help to identify patients with unfavourable long-term outcome. For instance, medio-ventricular and septal location of late gadolinium enhancement, degree of late gadolinium enhancement extent or high T2 mapping values are independent predictive factors of major cardio-vascular events. |
