Dilated cardiomyopathy (DCM) is defined by the presence of left ventricular or biventricular dilatation and systolic dysfunction in the absence of abnormal loading conditions or coronary artery disease sufficient to explain these changes. This is a heterogeneous disease frequently having a genetic background. Imaging is important for the diagnosis, the prognostic assessment and for guiding therapy. A multimodality imaging approach provides a comprehensive evaluation of all the issues related to this disease. The present document aims to provide recommendations for the use of multimodality imaging according to the clinical question. Selection of one or another imaging technique should be based on the clinical condition and context. Techniques are presented with the aim to underscore what is 'clinically relevant' and what are the tools that 'can be used'. There remain some gaps in evidence on the impact of multimodality imaging on the management and the treatment of DCM patients where ongoing research is important.
扩张型心肌病（DCM）的定义为左心室或双心室扩张和收缩功能障碍，而不存在足以解释这些改变的异常负荷条件或冠状动脉疾病。这是一种具有遗传背景的异质性疾病。影像学检查对于诊断、预后评估和指导治疗非常重要。多模态影像学方法可全面评估与该病相关的所有问题。本文件旨在根据临床问题提供多模态影像学应用的建议。选择一种或另一种影像学技术应基于临床情况和背景。本文介绍了各种技术，旨在强调哪些是“临床相关的”，哪些是“可使用的工具”。在多模态影像学对 DCM 患者的管理和治疗的影响方面，仍存在一些证据空白，因此正在进行的研究非常重要。
