摘要:
扩张型心肌病(Dilated Cardiomyopathy,DCM)是一种在没有异常负荷状况或冠状动脉疾病的情况下,存在左心室扩张和收缩功能障碍、不可逆性的心肌疾病,常合并心率失常、猝死等并发症,预后不良。影像学检查为其诊断、危险分层、指导治疗和预后评估的基础,超声心动图(Echocardiography, ECG)是最常用和最重要的检查方法,心脏磁共振(Cardiac Magnetic Resonance, CMR)技术可以检测和定性、定量评价心肌梗死和心肌纤维化。联合多种影像学成像技术能对DCM做出准确的诊断和评估,能为临床提供较为全面、科学和客观的信息。

Abstract:
Dilated cardiomyopathy (DCM) is a kind of diastolic and systolic dysfunction of left ventricular in the absence of abnormal load or coronary artery disease and an irreversible cardiomyopathy. It often combines arrhythmia, sudden death and other complications, and the prognosis is bad. Imaging examination is the basis for its diagnosis, risk stratification, guided treatment and prognosis assessment. Echocardiography (ECG) is the most commonly used and is the most important method of examination, Cardiac magnetic resonance (CMR) techniques can detect, qualitatively and quantitatively evaluate myocardial infarction and myocardial fibrosis. A combination of multiple imaging techniques allows accurate diagnosis and evaluation of DCM, and can provide more comprehensive, scientific and objective information for the clinic.
Key words:  Dilated cardiomyopathy  Echocardiography  Cardiac magnetic resonance imaging  Nuclear medicine
