摘要
扩散磁共振成像(dMRI)是一种非侵入性的、能提供生物体内水分子扩散运动相关信息的成像技术,可用于检测神经纤维微观结构的变化。而近几年来逐步发展起来的神经突方向分散度和密度成像(Neurite orientation dispersionand density imaging,NODDI)对脑白质微结构的研究更具有敏感性,同时也为中枢系统疾病的研究提供新的方法。本文对NODDI技术的成像原理及在中枢神经系统中的临床研究进展予以综述。
        The diffusion magnetic resonance imaging(dMRI) can provide the information of diffusion properties of water molecules in biological tissue, is the only noninvasive technique which can detect whiter matter microstructure. Neurite orien-tation dispersionand density imaging(NODDI) is a new technique which expands from diffusion magnetic resonance imaging,and has been demonstrated to be highly sensitive and specific in detecting the microstructure of biological tissues in vivo and providing an effective means for the study of central nervous system disorders. This article will review the principle of NODDI and its clinical application in neural system.
