The special m.r.i. technique , known as diffusion tensor imaging , is also being studied to help improve the diagnosis of concussions .

这种特殊形式的核磁共振成像技术被称为弥散张量成像，对这种技术的也用来提高诊断脑震荡的精确度。

The information used to build it comes from the analysis of two human brains , using magnetic resonance imaging ( mri ) and a variation of mri called diffusion tensor imaging .

建立脑图的信息来自于对两个人脑的分析，分析使用了磁共振成像（mri）和一种被称为扩散张量成像的mri的变体。

" The auditory area of her brain started taking over the somatosensory area , " says ro , who used diffusion tensor imaging , which focuses on the brain 's white matter connections , to spot the change .

罗使用磁共振扩散张量成像，试图发现女教授脑白质连接区的变化，他说：“她大脑躯体感觉区的功能正在被听觉区接管。”

Mri scans , computed tomography ( ct ) scans and diffusion tensor images ( dti ) use the magnetic signatures of different tissues , x-ray absorption , or the movement of water molecules in those tissues , to image the brain .

磁共振扫描（mri），电脑断层扫描（ct）和弥散张量成像（dti）利用不同组织的磁性特征、x射线吸收，或其中水分子的活动来给大脑成像。
