| 中文摘要: |
| 急性心肌梗死（AMI）的危险区（AAR）指梗死相关动脉所支配的心肌缺血区域，其最主要的组织学特点为水肿。准确评估AAR并推算可挽救心肌指数对于治疗AMI及评估预后有重要意义。心脏磁共振成像（CMRI）具有多参数、多模态的成像特点，可定性及定量评估心肌水肿和AAR。本文对CMRI评估AMI后AAR的研究进展进行综述。 |
| 英文摘要: |
| The area at risk (AAR) of acute myocardial infarction (AMI) is the area of myocardial ischemia dominated by infarct-related arteries, and its main histological feature is edema. Accurate evaluation of AAR and calculation of salvage myocardial index is of great significance for treatment of AMI and evaluation of prognosis. Cardiac MRI (CMRI) has the characteristics of multi-parameter and multi-modal imaging, which can be used to qualitatively and quantitatively assess myocardial edema and AAR. The research progresses of CMRI techniques for evaluation on AAR after AMI were reviewed in this article. |
