Key result
Comprehensive cardiac magnetic resonance using ECV evaluation alone or combined with T1 mapping achieved 96% sensitivity and 91% accuracy for detecting subacute myocarditis.
Why the study?
Detection of subacute myocarditis using CMR parameters can be challenging due to a lower degree of myocardial inflammation compared to the acute phase.
Does comprehensive cardiac magnetic resonance imaging accurately detect subacute myocarditis in patients with clinically suspected myocarditis?
Population
48 consecutive patients with clinically suspected myocarditis
Comparison
Acute (symptoms ≤2 weeks) vs subacute myocarditis (symptoms >2 to 6 weeks)
Design
Consecutive observational study

Does comprehensive cardiac magnetic resonance imaging accurately detect subacute myocarditis in patients with clinically suspected myocarditis?
Comprehensive CMR, particularly ECV and T1 mapping, provides high diagnostic accuracy for detecting subacute myocarditis, though differentiating it from acute myocarditis remains challenging due to overlapping findings.
Brendel et al. (2022) conducted an observational in clinically suspected myocarditis (n=48). Comprehensive cardiac magnetic resonance (CMR) with ECV and T1 mapping vs. Acute myocarditis was evaluated on Detection of subacute myocarditis. Comprehensive cardiac magnetic resonance using ECV evaluation alone or combined with T1 mapping achieved 96% sensitivity and 91% accuracy for detecting subacute myocarditis.
