摘　　要：目的：为了及早诊治外伤性颅内迟发性病变，探索ＣＴ复查的合适时间。材料与方法：搜集颅脑外伤后ＣＴ复查时发现新病变的ＣＴ资料１３１例，统计分析颅内的新病变和发现新病变的时间。结果：发现颅内迟发性病变２０１个，常见的病变有颅内血肿，脑挫裂伤和硬膜下积液等。接近半数的病变在伤后３天内出现，１０天内发现的病变占８４％。结论：颅脑外伤后３、６、１０天是ＣＴ复查的最佳时机。Objective: To investigate the appropriate CT reexamination time for promptly disclosing delayed intracranial lesions due to trauma. Materials and Methods: Newlyappeared lesions were found on reexamined CT scans in 131 cases with craniocerebral trauma. The new intracranial lesions and their appearing time were analyzed. Results: On reexamination CT scan, 201 delayed intracranial lesions were discovered, including, mainly, intracranial hematoma, cerebral contusion and/or laceration, and subdural fluid accumulation, etc. About half of the lesions occurred within 3 days after trauma, 84% of the lesions were detected within 10 days after trauma. Conclusion: The optimal time to take CT reexamination is at the 3rd, 6th and 10th day after craniocerebral trauma. Delayed intracranial lesions can be demonstrated on CT scan within 10 days after trauma.
