Myocarditis following COVID-19 mRNA vaccination is a rare adverse reaction with an incidence rate of approximately 0.0011%.1 Cardiac magnetic resonance imaging (CMR) allows for non-invasive assessment of myocardial tissue characterization, including myocardial oedema and fibrosis, and has high diagnostic accuracy for diagnosing acute myocarditis.2 A recent study demonstrated the MRI characteristics of myocarditis after mRNA vaccination, slightly different from other-cause of myocarditis; the most frequent location of late gadolinium enhancement (LGE) was the epicardial side of the basal inferolateral wall.3 Because the frequency of abnormalities on CMR is not well understood, we have performed a literature search and meta-analysis to evaluate the imaging characteristics of myocarditis after mRNA vaccination on CMR.
