【摘要】 本文对９０例急性颅脑外伤后１５’─１天的ＣＴ表现，其中１小时之内３８／６０例作了回顾性分析．颅内血肿３３例．脑挫伤及／或裂伤４２例，骨折２３例。提出了受伤侧侧脑室形态与位置的改变，及双侧脑为宽度的差异有助于对不典型等密度血肿的确定。ＣＴ表现难于严格区分脑挫伤及／或裂伤的病理界限，同一病人这两种病理改变可同时存在。颅底与乳突部位的骨折以及颅盖部粉碎性或凹陷性骨折所致直接或间接的脑损伤，ＣＴ检查优于常规Ｘ线检查，因骨折导致对冲性脑损伤应予重视。更多还原

【Abstract】 The CT manifestations of sixty cases of acute craniocerebral trauma included 38 wounded within one hour and others one day only were teviewed. Intracranial hematomas 33,brain contusion-laceration 42 and skull fracture 23 are mainly CT findings in this series. It is easily to establish the CT diagnosis above mentioned in patients with typical CT images. Pay attention to shift the site,size, shape of injured lateral ventricle,to differ the width of bilateral brain sulci,it woula be helpful to diagnose atypical’isodense hematoma. Differentiating the boundary between traumic brain contusion and brain laceration is very difficult because these both alterings might be simultaneously presented in one patient with skull wounded. CT scan is superior to convetiona X--ray examination for observing fracture located basicranial and mastoid and the degree of brain tissue to be directly or correspondingly in juted due to chip,crushed,deptessed skull fracture.更多还原
