In acute stage of traumatic brain injury, it is not easy to diagnose diffuse axonal injury (DAI) by computer imaging. Even in chronic stage, DAIs occasionally show no remarkable abnormality by ordinal CT or MRI images. We retrospectively studied 32 DAI cases by the Functional Independence Measure (FIM), a battery of neuropsychological tests and CT or MRI films of acute and chronic phase. The result showed decrease of cognitive function in 32 DAI cases. The degree of enlargement of the ventricles in chronic stage did not correlate with cognitive dysfunction.
在创伤性脑损伤的急性期，通过计算机成像诊断弥漫性轴索损伤（DAI）并不容易。即使在慢性期，常规CT或MRI图像上的DAI偶尔也无明显异常。我们通过功能独立性测量（FIM）、一系列神经心理学测试以及急性期和慢性期的CT或MRI影像，对32例DAI病例进行了回顾性研究。结果显示，32例DAI病例存在认知功能下降。慢性期脑室扩大的程度与认知功能障碍无关。
