Objective: The purpose of our study was to investigate whether cardiovascular magnetic resonance imaging can detect early myocardial tissue edema as a first step in the development of myocarditis.
Methods: We examined 36 consecutive patients who were presented with symptoms of fatigue, weakness, and/or palpitations after respiratory tract infection but normal left ventricular function and compared these patients with 21 consecutive controls without acute symptoms. Electrocardiogram-triggered, T2-weighted, fast spin echo triple-inversion recovery sequences were performed in all patients.
