Over the past ten years, cardiac MRI has become an indispensable tool for acute myocarditis diagnosis. Under appropriate conditions, cardiac MRI may allow postponement of initial coronary angiography in many instances. The 2020 ESC guidelines give a class I recommendation to its use in the setting of MINOCA for differential diagnosis between acute myocardial infarction, myocarditis, Tako-Tsubo and other cardiac pathologies, in order to improve therapeutic management and follow-up. This article describes the technical characteristics of MRI in myocarditis (Lake Louise diagnostic criteria and criteria based on myocardial tissue mapping), the main differential diagnoses, the prognostic value and addresses the issue of myocarditis in the setting of COVID-19.
在过去十年中，心脏磁共振成像已成为急性心肌炎诊断不可或缺的工具。在适当情况下，心脏磁共振成像在许多情况下可推迟首次冠状动脉造影。2020年欧洲心脏病学会（ESC）指南对其在心肌梗死伴非阻塞性冠状动脉病变（MINOCA）情况下用于鉴别急性心肌梗死、心肌炎、应激性心肌病和其他心脏疾病给出了I类推荐，以改善治疗管理和随访。本文描述了心肌炎磁共振成像的技术特征（路易斯湖诊断标准和基于心肌组织成像的标准）、主要鉴别诊断、预后价值，并探讨了新型冠状病毒肺炎（COVID-19）背景下的心肌炎问题。
