摘要
目的探讨功能磁共振(MR)成像在心脏死亡器官捐献(DCD)供肝热缺血再灌注损伤评估中的应用情况。方法对关于功能MR成像原理及其在肝脏热缺血再灌注损伤评估中应用的相关文献进行综述并进行分析总结。结果目前应用于肝脏热缺血再灌注损伤评价的功能MR技术主要包括扩散加权成像、体素内不相干运动、扩散张量成像、血氧气水平依赖性MRI、MRI特异性对比剂增强检查、T2 mapping等,这些技术目前主要用在对动物模型的评价中。结论从目前动物模型研究结果看,功能MR成像能够无创、定量评价活体肝脏组织的微观信息变化,对进一步认识肝脏热缺血再灌注损伤的机制及其预后评估具有重要价值,特别是随着DCD的开展,功能MR成像将在肝脏热缺血再灌注损伤评估中发挥重要的作用。
        Objective To explore performances of functional magnetic resonance imaging(MRI) in evaluation of hepatic warm ischemia-reperfusion injury. Method The relative references about the principle of functional MRI and its application in the assessment of hepatic warm ischemia-reperfusion injury were reviewed and summarized. Results The main functional MRI techniques for the assessment of hepatic warm ischemia-reperfusion injury included the diffusion weighted imaging(DWI), intravoxel incoherent motion(IVIM), diffusion tensor imaging(DTI), blood oxygen level dependent(BOLD), dynamic contrast enhancement MRI(DCE-MRI), and T2 mapping, etc.. These techniques mainly used in the animal model with hepatic warm ischemia-reperfusion injury currently. Conclusions From current results of researches of animal models, functional MRI is a non-invasive tool to accurately and quantitatively evaluate microscopic information changes of liver tissue in vivo. It can provide a useful information on further understanding of mechanism and prognosis of hepatic warm ischemia-reperfusion injury. With development of donation after cardiac death, functional MRI will play a more important role in evaluation of hepatic warm ischemia-reperfusion injury.
