缺血性脑卒中的神经影像学进展

The progress in neuroimaging of ischemic stroke

当一个人不幸中风时,必须明确发病机制、病理生理学改变以及评估中风的恢复潜力。临床技术进步让卒中的多个阶段,包括预防、急性中风和中风后恢复,都得到了更好的监测和治疗。神经影像学技术的飞速发展可量化组织功能和评估预后,从而分类患者以进行预防性和个性化治疗。本综述将重点陈述目前评估缺血性卒中的高级磁共振技术,如磁共振扩散谱成像(diffusion spectrum imaging,DSI)和血氧水平依赖性功能核磁共振成像(blood oxygen level-dependent functional magnetic resonance imaging,BOLD-fMRI),并对其优缺点进行总结。

When a man suffers from stroke,some issues must be addressed,including stroke pathogenesis,pathophysiology,and evaluation of recovery potential.Advances in clinical technology have allowed for better monitoring and personalized therapy in different stages of stroke,including prevention,acute stroke and post-stroke rehabilitation.The development of neuroimaging can quantify tissue function and healthy status,so as to triage patients for preventative treatment and optimize their therapies.This review will focus on the progress of advanced MRI neuroimaging methods in ischemic stroke.
