Diagnosis of nonischemic cardiomyopathy is a challenging process that influences patient morbidity and mortality. Currently, the well known World Health Organization classification has been revisited by an American Heart Association expert consensus panel. The contemporary classification is compatible with the rapid evolution in molecular genetics and evolving diagnostic tools such as cardiac magnetic resonance imaging (MRI). Magnetic resonance imaging is a robust diagnostic tool that offers various techniques to assess the function, morphology, perfusion, and scarring of myocardial tissue thus providing better understanding of the underlying causes of nonischemic cardiomyopathies. In this review, we discuss the current role of cardiac MRI in the evaluation of nonischemic cardiomyopathy, in the context of the current American Heart Association classification of these disorders.
非缺血性心肌病的诊断是一个具有挑战性的过程，会影响患者的发病率和死亡率。目前，美国心脏协会专家共识小组对著名的世界卫生组织分类进行了重新审视。当代分类与分子遗传学的快速发展以及诸如心脏磁共振成像（MRI）等不断发展的诊断工具相兼容。磁共振成像是一种强大的诊断工具，提供各种技术来评估心肌组织的功能、形态、灌注和瘢痕形成，从而更好地了解非缺血性心肌病的潜在病因。在本综述中，我们结合美国心脏协会目前对这些疾病的分类，讨论心脏MRI在非缺血性心肌病评估中的当前作用。
