摘要
心肌炎是临床常见的儿童获得性心脏病,是以水肿、充血、坏死或纤维化为特点的心肌炎症性病变。心内膜心肌活检是目前诊断心肌炎的金标准,但由于其有创性和取样误差大而很少应用于临床。磁共振具有无创、高空间分辨率和多方位、多参数成像等特点,其T2加权、早期钆增强序列、延迟钆增强序列能够较好地反映心肌炎的组织病理学特征(水肿、充血、纤维化/坏死),已用于心肌炎的诊断。
Myocarditis is a common acquired heart disease in children, which is characterized by myocar- dial edema, congestion, necrosis or fibrosis. Currently, endomyocardial biopsy is the gold standard for the diagnosis of myocarditis,but it is rarely used in clinical because its invasiveness and large sampling error. Magnetic resonance imaging has the characteristics of non-invasive, high spatial resolution, multi-direction and multi-parameter imaging, and its T2 weighted, early gadolinium enhanced sequence, delayed gadolinium enhanced sequence can better reflect the morphological characteristics of myocarditis:edema, congestion, necrosis or fibrosis, and has been used in the diagnosis of myocarditis.
