弥散张量成像在意识障碍诊断中的应用

弥散张量成像（DTI）是一种非侵袭性的核磁成像技术，能够识别传统CT和MRI难以发现的脑微观结构改变，特别是神经纤维束变化和方向，目前DTI已成熟地应用于基础实验和临床研究中，能为严重脑损伤患者发现物标志物并且预测预后提供参考，DTI也在意识障碍的诊断和预后预测领域进行了很多探索研究。

Diffusion tensor imaging in the diagnosis of disorder of consciousness

Diffusion tensor imaging (DTI) is a kind of noninvasive MRI, to identify the traditional CT and MRI finding of cerebral microstructure change, especially the nerve fiber bundles and direction change, at present, the DTI has applied in basic experiment and clinical study, for patients with severe brain injury finding markers and provide reference for predicting prognosis, DTI is also in the field of consciousness disorder diagnosis and prognosis prediction for a lot of exploration research.
