摘　　要：目的 :分析脑弥漫性轴索损伤 (DAI)的急性期表现 ,为临床诊断DAI提供影像学依据。材料和方法 :收集 1 4例DAI的临床及CT资料进行回顾性分析。结果 :1 4例DAI的CT表现为弥漫性脑肿胀 1 4例 ,脑实质内出血灶 1 1例 ,呈单发或多发 ,直径 <2cm。主要分布于皮髓质交界、胼胝体、基底节区和脑干 ,蛛网膜下腔出血 9例 ,合并硬膜下或硬膜外出血 4例 ,颅骨骨折 2例。结论 :DAI的临床与CT表现特点 ,对早期正确诊断具有重要意义。Objective 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 The CT imagesdata and its correlated clinic feature of 14 cases with DAI were analyzedretrospectively.Results Thediffuse brainedema were found in 14 cases.11 cases had hemorrhagelesions(less than 2 cm in diameter)in brain parenchyma which were at corticomedullaryjunction,callosum,brain stem,basal gandlia,internal capsule.Subarachnoid hemorr hage 9 cases,4 cases were associated with,epidural hematoma/subdural hematoma,and skull fracture 2 cases.Conclusion CT manifestation and its correlated clinic feature of DAI can provide reliable evidence for the earlyaccurate diagnosis of DAI.
