| 摘 要： | 钆对比剂延迟强化磁共振成像(LGE-MRI)具有高度的组织特异性和良好的空间分辨力,能够准确识别梗死心肌或瘢痕组织。钆对比剂延迟强化(LGE)可见于缺血性心脏病,如急性或慢性心肌梗死,也可见于非缺血性心肌病、炎症性心脏病和浸润性心肌病。延迟强化的有无及其部位和程度在心血管疾病的诊断、治疗和预后判断方面起着重要作用。

| Abstract: | Late gadolinium enhancement MRI (LGE-MRI) can accurately identify myocardial infarction or scar tissue with high tissue specificity and good spatial resolution. Late gadolinium enhancement (LGE) can be seen in ischemic heart diseases such as acute or chronic myocardial infarction, also in non-ischemic cardiomyopathy, inflammatory heart diseases and infiltrative cardiomyopathy. LGE plays an important role in diagnosis, treatment and prognosis of cardiovascular diseases. |
