摘　　要：磁共振成像(MRI)技术在评估脑的解剖结构及功能变化方面得到广泛应用。体素内不相干运动(IVIM)成像是近年发展起来的无创评价活体组织内分子扩散运动及灌注的MRI新技术,今后在急性缺血性脑卒中的诊断中将发挥越来越重要的作用。本文对IVIM成像的原理及其在急性缺血性脑卒中中的应用价值研究进展予以综述。Magnetic resonance imaging(MRI)techniques are widely used to assess anatomical and functional changes in the brain.Intra-voxel incoherent motion(IVIM)imaging is a new MRI technique developed in recent years for the non-invasive evaluation of molecular diffusion motion and perfusion in living tissue.It will play an increasingly important role in the diagnosis of acute cerebral infarction in the future.This paper reviewed the research progress on the principles of IVIM imaging and its application in acute ischemic stroke.
