The use of cardiovascular magnetic resonance (CMR) has been implemented in the diagnostic work-up of patients with cardiomyopathies by providing an accurate assessment of biventricular volumes and function and a detailed myocardial tissue characterization in a one-stop-shop multi-parametric imaging technique. Its unique capability to perform an accurate tissue characterization of the myocardium, which is superior to other imaging modalities, has prompt its use in the analysis of myocardial arrhythmic substrates and in the prognostic risk stratification of patients. Although left ventricular ejection fraction (LVEF) has always been the best-known predictor of arrhythmic risk, the quantification of myocardial scar by CMR has been recognised as a powerful risk stratification tool, independent of LVEF. Moreover, due to its ability to identify myocardial arrhythmic substrate, both ventricular but more recently also atrial, CMR is increasingly offered as a guide to ablation procedures.
心血管磁共振成像（CMR）已应用于心肌病患者的诊断检查，它是一种一站式多参数成像技术，能够准确评估双心室容积和功能，并对心肌组织进行详细表征。CMR对心肌进行准确组织表征的独特能力优于其他成像方式，这促使其被用于分析心肌心律失常基质以及患者的预后风险分层。尽管左心室射血分数（LVEF）一直是最广为人知的心律失常风险预测指标，但CMR对心肌瘢痕的量化已被公认为一种强大的风险分层工具，独立于LVEF。此外，由于CMR能够识别心肌心律失常基质，包括心室以及最近发现的心房，它越来越多地被用作消融手术的指导。
