Application of magnetic resonance diffusion tensor imaging in normal brain aging / 中国医学影像技术

ABSTRACT

Brain aging refers to the gradual decline of brain tissue structure,function and morphology with age.The cognitive dysfunction is an important marker of brain aging.Degenerative brain white matter changes may be an important factor in brain aging.DTI and its image processing techniques can noninvasively display the microstructure of human brain in vivo.Additionally,it is beneficial to analyze aging process of brain and related diseases of brain aging.The current status and progresses of diffusion tensor imaging in normal brain aging were reviewed in this article.
