| 摘 要： | Objective To explore pathogenesis, imaging findings, diagnostic and therapeutic methods of diffuse brain injury (DBI) in order to improve the cure rate and decrease mortality and deformity. Methods A retrospective analysis was done upon injury causes and types, treatment measures and prognosis of 871 cases with DBI. Results The main causes for DBI were traffic accidents and fall from height. The main types of DBI were diffuse axonal injury and diffuse brain edema, which could be complicated with subarachnoid hemorrhage,brain contusion, intracranial hemorrhage and brain hematoma. On admission, there were 660 cases (75. 8%) with Glasgow Coma Scales (GCS) of 8 or less, among whom there were 365 cases (41. 9%) with GCS of 3-5. The cure rate was 75. 4% (675/871), and the mortality rate 19.7% (172/871). But the mortality rate of those with GCS of 5 or less was as high as 39. 2% (143/365). Conclusion The diagnosis of DBI is mainly based on the clinical manifestation and the imaging findings of CT and MRI. Comp
