摘　　要：与传统扩散加权成像 (diffusionweightedimaging ,DWI)相比 ,扩散张量成像 (diffusiontensorimaging ,DTI)能够更加准确的反映分子扩散的方向性 ,因而在显示脑白质纤维走行及白质相关的脑部疾病等方面显示出巨大的优越性。Diffusion tensor imaging is a new technology which can reflect the direction of molecule diffusion comparing with diffusion weight imaging, diffusion tensor imaging has great advantage on showing the distribution of white matter fiber and brain disease involved the white matter. This article reviews the arithmetic and application of diffusion tensor imaging in medicine.
