Aim: To evaluate our experience with the use of contrast magnetic resonance (CMR) in patients suspected from acute myocarditis.


Material and method. During 2006-2008 we performed CMR in 11 patients (4 female, average age 43.2 years) indicated from coronary intensive care unit, 7 underwent some infectious disease before the onset of cardiac symptoms. Interval between begin of symptoms and CMR was 1-9 days (average 3.5).
The standard protocol with sequences for assessment of kinetics (trueFISP), changes in early myocardial perfusion (turboFLASH) and delayed sequence (inversion recovery FLASH) to evaluate late enhancement (LE) were used.

Results: The foci of LE in subepcardial and intramyocardial localization specific for acute mycarditis were found in 10 patients. Changes were distributed mainly in segments of free lateral wall of left chamber. There were no defects of early myocardial perfusion, whereas mild focal hyperperfusion was seen in 4 patients. In all patients, the acute coronary syndrome was excluded; following clinical development in patients with positive LE in CMR indicated for acute myocarditis.

Conclusion: Contrast magnetic resonance is important part of diagnostic algorithm in patients suspected from acute myocarditis. Combined protocol contained assessment of early myocardial perfusion and late enhancement improves specificity of the method and allows to differentiate between myocarditis and myocardial infarction.
