| 摘 要： | 目的探索评价MRI增强延迟扫描技术对判断心肌存活性的价值。方法 20例患者行MRI增强延迟扫描检查,分析心肌延迟扫描图像并探索评价心肌存活性。结果 17例左室心肌未见梗塞灶,增强延迟扫描MR表现为均匀一致低信号,心肌内无对比剂存留。3例陈旧性心肌梗死表现为左心室病变区局限性信号不均匀增高,对比剂存留。结论 MRI增强延迟扫描技术可对心肌存活性作出一定评价,为患者制订治疗方案和预后评价提供信息。

| Abstract: | Objective To evaluate the value of MRI delayed enhancement in assessment of myocardial viability. Methods 20 patients underwent MR delayed enhancement imaging, images were analyzed and myocardial viability can be drawn. Results unanimous low signal intensity was shown on normal myocardial viability, asymmetry high signal intensity was shown on myocardial infarct. In our study, 17 cases were normal, and 3 cases demonstrated asymmetry high signal intensity on delayed enhancement images. Conclusion Myocardial viability can be demonstrated on delayed enhancement images, and it is valuable to clinic treatment. |
