The identification of diffuse axonal injury (DAI) can be difficult, especially using conventional imaging (CT or MRI), which usually appears normal. Diffusion tensor imaging (DTI) is useful in identifying white matter abnormalities in patients with DAI. We describe the case of a 17-year-old female with severe closed head injury and right-side hemiparesis, studied with DTI and MR-tractography. In this case, DTI was useful to detect focal and diffuse signs of DAI.
弥漫性轴索损伤（DAI）的识别可能具有挑战性，尤其是使用传统成像方法（CT或MRI）时，其结果通常显示正常。弥散张量成像（DTI）有助于识别DAI患者的白质异常。我们描述了一名17岁女性的病例，她因严重闭合性颅脑损伤和右侧偏瘫接受了DTI和磁共振纤维束成像检查。在该病例中，DTI有助于检测DAI的局灶性和弥漫性征象。
