Cardiac MRI (CMR) and electrocardiogram (ECG)-gated multi-detector computed tomography (MDCT) are increasingly important tools in the identification and assessment of cardiac-related disease processes, including those associated with sudden cardiac death (SCD). While the commonest cause of SCD is coronary artery disease (CAD), in patients under 35 years inheritable cardiomyopathies such as hypertrophic cardiomyopathy and arrhythmogenic right ventricular cardiomyopathy are important aetiologies. CMR in particular offers both accurate delineation of the morphological abnormalities associated with these and other conditions and the possibility for risk stratification for development of ventricular arrhythmias with demonstration of macroscopic scar by delayed enhancement imaging with intravenous gadolinium.
心脏磁共振成像（CMR）和心电图（ECG）门控多层螺旋计算机断层扫描（MDCT）在识别和评估心脏相关疾病过程中，包括与心源性猝死（SCD）相关的疾病，正日益成为重要工具。虽然SCD最常见的原因是冠状动脉疾病（CAD），但在35岁以下的患者中，遗传性心肌病如肥厚型心肌病和致心律失常性右心室心肌病是重要病因。特别是CMR既能够准确描绘与这些及其他病症相关的形态学异常，又能够通过静脉注射钆剂延迟强化成像显示宏观瘢痕，从而对室性心律失常的发生进行危险分层。
