Recent technologic advances in cardiac magnetic resonance (MR) imaging have resulted in images with high spatial and temporal resolution and excellent myocardial tissue characterization. Cardiac MR is a valuable imaging technique for detection and assessment of the morphology and functional characteristics of the nonischemic cardiomyopathy. It has gained acceptance as a standalone imaging modality that can provide further information beyond the capabilities of traditional modalities such as echocardiography and angiography. Black-blood fast spin-echo MR images allow morphologic assessment of the heart with high spatial resolution, while T2-weighted MR images can depict acute myocardial edema. Contrast material-enhanced images can depict and be used to quantify myocardial edema, infiltration, and fibrosis. This review presents recommended cardiac MR protocols for and the spectrum of imaging appearances of the nonischemic cardiomyopathies.
近年来，心脏磁共振（MR）成像技术取得了进展，其图像具有高空间和时间分辨率以及出色的心肌组织特征描述能力。心脏磁共振是一种有价值的成像技术，可用于检测和评估非缺血性心肌病的形态和功能特征。它已被广泛接受为一种独立的成像方式，能够提供传统成像方式（如超声心动图和血管造影）无法提供的更多信息。黑血快速自旋回波 MR 图像可提供具有高空间分辨率的心脏形态评估，而 T2 加权 MR 图像可描绘急性心肌水肿。对比增强图像可描绘和用于量化心肌水肿、浸润和纤维化。本综述介绍了非缺血性心肌病的心脏磁共振推荐检查方案和成像表现谱。
