与严重缺血引起的心肌缺血性坏死相同,任何原因引起的心肌组织和心肌细胞的损伤与坏死都能引起磁共振心肌延迟显像的增强。即钆造影剂在心肌细胞的间隙滞留。而这些非缺血性心肌细胞的损伤及坏死表现与缺血性损伤有两点不同,一是位于心肌壁的中层或心外膜下,如特发性扩张型心肌病,肥厚型心肌病、心肌炎、结节病、Fabry病等,且其分布相对随机,不符合冠状动脉灌注区域。
As with ischemic necrosis caused by severe ischemia, damage and necrosis of myocardial tissue and cardiomyocytes caused by any cause can all cause the enhancement of myocardial MR imaging. That gadolinium contrast agent in the myocardial cell gap retention. These non-ischemic myocardial cell injury and necrosis and ischemic injury performance and there are two differences, one is located in the middle of the myocardial wall or epicardial, such as idiopathic dilated cardiomyopathy, hypertrophic cardiomyopathy, Myocarditis, sarcoidosis, Fabry disease, etc., and its distribution is relatively random, does not meet the coronary perfusion area.
