Background: There is a need for the systematization, generalization and analysis of the structural changes of the myocardium, occurring in patients with myocarditis. This disease is rare; therefore, structured information in the field of radiological diagnostics is still insufficient within national publications.

Aim: The study purpose was to determine the significance and specificity of changes observed in cardiac magnetic resonance images in patients with myocarditis, and to compare the obtained results with the literature data.

Methods: 7 patients, including children aged 4 and 6, with a verified diagnosis of myocarditis were retrospectively examined.

Results: The analysis of the obtained images revealed the most common changes related to myocarditis, such as myocardial edema, impaired myocardial contractility, increased delayed accumulation of the contrast agent. The pathophysiological mechanisms of the found structural changes were analyzed and described.

Conclusion: Magnetic resonance imaging is the most important non-invasive method for diagnosing myocarditis, which allows one to identify the lesion of the heart muscle, to assess the extent of its damage, to differentiate myocarditis from other diseases, as well as to assess the dynamics when evaluating the effectiveness of therapy.

Обоснование. Необходимы систематизация, обобщение и анализ структурных изменений миокарда, возникающих у пациентов с миокардитом. Данное заболевание является редкой нозологией, поэтому среди отечественных публикаций сохраняется недостаток структурированной информации в области лучевой диагностики.

Цель исследования — определение значимости и специфичности изменений при анализе результатов магнитно-резонансной томографии сердца у пациентов с миокардитами и их сопоставление с данными литературы.

Методы. Ретроспективно обследованы 7 пациентов, включая детей в возрасте 4 и 6 лет, с верифицированным диагнозом миокардита.

Результаты. При анализе полученных изображений выявлены наиболее распространённые изменения, такие как отёк миокарда, нарушение сократимости миокарда, повышенное накопление контрастного препарата в отсроченные фазы. Проанализированы и описаны патофизиологические механизмы возникновения структурных изменений.

Заключение. Магнитно-резонансная томография является важнейшим неинвазивным методом диагностики миокардита, позволяющим выявить поражение сердечной мышцы, оценить степень её повреждения, дифференцировать миокардит с другими заболеваниями, а также оценить динамику при оценке эффективности терапии.
