| 中文摘要: |
| 目的 用MRI 评价急性心肌梗塞(AMI) 有无再灌注。方法 将21 例确诊为AMI 者分为有再灌注和无
再灌注两组;2 组均行MRI T1 、T2 加权和增强扫描,然后测量每例心功能和梗塞灶重量。结果 梗塞心肌明显强
化;有再灌注组强化表现为透壁且均匀,无再灌注组强化表现为透壁但不均匀(周边强化) ;前者心功能较后者好,梗
塞灶重量则较后者轻。结论 MR 增强扫描可评价梗塞心肌有无再灌注。 |
| 英文摘要: |
| Objective To evaluate the value of MRI in diagnosing acute myocardial infarction (AMI) with reperfusion or
no-reperfusion. Methods 21 patients with first AMI proved by clinical materials were classified into reperfusion group and
no-reperfusion group.Both group patients underwent MRI T1 、T2weighted sequence and enhanced scanning. We also measured the cardiac function and the infarct size. Results Infarcted myocardium were enhanced markedly. The enhancement
pattern of the reperfusion group is transmural and homogeneous enhancement ,the no-reperfusion group is transmural and
marginal enhancement with less enhanced area centrally. The reperfusion group had a better cardiac function than the noreperfusion group and smaller infarect size than the no-reperfusion group. Conclusion Enhanced-MRI can assess AMI with
reperfusion or without reperfusion. |
