脑弥漫性轴索损伤的CT诊断

CT Diagnosis of Diffuse Axonal Injury

目的：分析脑弥漫性轴索损伤（DAI）的急性期CT表现，为临床诊断DAI提供影像学依据。材料和方法：分析0例临床拟诊为DAI的早期CT表现。结果：CT可见①弥漫性脑肿胀；③皮层下及脑深部小出血灶；③蛛网膜下胜出血及脑室内出血，硬膜下／外出血。结论：对有上述CT征象者，结合临床表现，可考虑诊断为DAI。

To Study the CT signs of DAI in acute phase of brain injury in order to provide a imaging evidence for the diagnosis of DAI. Materials and Methods: CT scan of 60 cases of DAI diagnosed clinically were analysed. Results:The manifestations on CT scan were: ①difuse cerebral swelling; ②subcortical or small deep cerebral hematoma; ③subarachnoid hemorrhage, epidural or subdural hemotoma. Conchusion: Combining with clinical findings, the patients revcaled CT signs listed above may be diagnosed as DAI.
