【摘要】 目的 探讨CT薄层高分辨重建技术在颅底骨折诊断中的应用价值。方法 对经过筛选的32例可疑颅底骨折患者进行CT常规及薄层高分辨重建技术检查，并对其诊断结果进行分析、比较。结果 32例外伤患者的常规CT检查中有24例怀疑有颅底骨折(75%)，但不能确诊，而通过薄层高分辨重建技术检查，24例均可确诊为颅底骨折(100%)。薄层高分辨图像可清晰显示骨折线，并有多幅图像支持诊断。结论 CT薄层高分辨重建技术对诊断颅底骨折具有优越性，为临床治疗和法医学鉴定提供直接依据。【关键词】 颅骨骨折，基底；体层摄影，X线计算机；诊断

【Abstract】 Objective To evaluate the value of high resolution CT(HRCT) technique in the diagnosis of basicranial fracture.Methods 32 cases of brain trauma who underwent routine CT scanning were examined with thin-layer basicranial scanning and the imags were reconstructed and studied.Results On routine CT scanning,only 24 cases were suspected to basicranial fracture(75%),while on thin-layer scanning and reconstructed images,all the cases were diagnosed as basicranial fracture with certainty(100%).On thin-layer high resolution images,fracture line was obvious and the diagnosis was supported by several images in each patient.Conclusion It has superiority of high resolution CT(HRCT) technique in the examination of basicranial fracture.It could give direct evidence for clinical and forensic medical diagnosis and differenciation. ......
