2024年10月8日 · Late gadolinium enhancement is a technique used in cardiac MRI for cardiac tissue characterization, in particular, the assessment of myocardial scar formation and regional myocardial fibrosis 1-5. Late gadolinium enhancement is also known under the terms ‘late enhancement’ or ‘delayed enhancement’.

延迟强化是心脏增强扫描中非常重要的一部分，LGE（Late Gadolinium Enhancement）特指心脏检查中打药以后延迟一段时间在进行扫描。 静脉注射对比剂（一般是 钆剂 后），等10~15min对心脏进行扫描（一般以扫描心肌的几个位置为主，当然目前流行3D扫描）。 延迟强化对于心肌活性的判断，心肌有无瘢痕、坏死是非常重要的。 可以说打药的心脏扫描，延迟强化的重要性大于首过灌注，在组织定量学检查出现之前（T2、T1 mapping），LGE是心脏扫描中最重要的一个序 …

Cardiovascular magnetic resonance (CMR) has significantly revolutionized the comprehension and diagnosis of cardiac diseases, particularly through the utilization of late gadolinium enhancement (LGE) imaging for tissue characterization.

2022年1月21日 · lge-mri可直接检测梗死心肌的位置和范围，清晰显示其透壁程度，全面、准确评价梗死心肌的三维分布，全面评价心肌活性，从而合理筛选接受再血管化治疗的患者，有效预估再血管化治疗后心功能整体及局部的改善。

We review characteristic CMR features in ischemic and non-ischemic cardiomyopathies (ICM and NICM), especially in terms of the location and distribution of late gadolinium enhancement (LGE). CMR in ICM shows segmental wall motion abnormalities or wall thinning in a particular coronary arterial territory, and the subendocardial or transmural LGE.

2013年12月20日 · Late gadolinium enhancement (LGE) by cardiac MR (CMR) is a predictor of adverse cardiovascular outcomes in patients with nonischemic cardiomyopathy (NICM). However, these findings are limited by single-center studies, small sample sizes, and low event rates.

2025年1月15日 · Late gadolinium enhancement (LGE) on cardiac MRI is an established marker of myocardial replacement fibrosis [1]. Both the presence and extent of LGE have been shown to predict adverse outcomes in a range of cardiac diseases [1,2].

Key points: · LGE MRI is the reference standard for the noninvasive assessment of myocardial viability. · LGE MRI is used to diagnose a broad range of non-ischemic cardiomyopathies in everyday clinical practice.. · Improvements in spatial resolution and scar-to-blood contrast further strengthened its position.

With the introduction of gadolinium contrast agents in cardiac MR, a new principle was established: late gadolinium enhancement imaging (LGE). The concept is based on the delayed wash in and wash out in tissue with an increased proportion of extracellular space.

2023年8月23日 · Evidence is rapidly growing for the impact of myocardial scar identified by late gadolinium enhancement (LGE) cardiac magnetic resonance imaging (CMR) on cardiovascular events. We aim to assess...
