2、数、侧脑室后角指数评估脑室宽度，发现前后放射冠各向异性值和表观弥散系数的增大与正常衰老过程中脑室扩大相关，这些会影响脑室周围白质，并将进一步导致衰老过程中的认知和感觉运动功能减退。显示结果的文章发表在中国神经再生研究（英文版） 杂志 2014 年 5 月第 9 期。Article: “ Age-related changes of lateral ventricular width and periventricular white matter in the human brain: a diffusion tensor imaging study“ by Yong Hyun Kwon1,

They detected four regions of interest in the periventricular white matter of 60 normal subjected aged 20-78 years using DTI technique: the anterior corona radiata, the posterior corona radiata, and the genu and splenium of the corpus callosum. They also assessed ventricular widt
