目的　通过 2种扫描方法的对比 ,探讨CT薄层扫描 ,高分辨重建技术的特点 ,各类参数的使用 ,以及该技术在颅底骨折检查中的优越性。方法　对经筛选的 2 8例脑外伤病人除进行常规CT检查外 ,又对其颅底进行薄层扫描 ,并进行高分辨重建。结果　 2 8例脑外伤病人在常规CT检查时 ,只有 2 0例怀疑有颅底骨折 ( 71.4%) ,但不能确诊 ,在进行薄层扫描 ,并进行高分辨重建后 ,2 8例均可确诊为颅底骨折 ( 10 0 %)。高分辨薄层图像 ,清晰显示骨折线 ,并且每个病例有多幅图像支持诊断。结论　对疑有颅底骨折的病人 ,正确而熟练地运用CT薄层扫描 ,并进行高分辨重建 ,能明确诊断 ,减少误诊

Objective To compare the advantages of CT scanning with high resolution reconstruction and the use of various parameters and the superiority of this technique in the examination of skull base fracture. Methods Twenty-eight traumatic brain injury patients were screened by thin-section scan and high-resolution reconstruction in addition to routine CT examination. Results Twenty-eight cases of traumatic brain injury were diagnosed as skull base fracture (71.4%) during routine CT examination but could not be diagnosed. Twenty-eight cases were diagnosed after thin-layer scanning and high-resolution reconstruction The skull fracture (10 0%). High-resolution, thin-layer images clearly show the fracture line, with multiple images in each case supporting diagnosis. Conclusions For patients suspected of skull base fracture, the correct and expert use of CT thin-layer scanning and high-resolution reconstruction can confirm the diagnosis and reduce the misdiagnosis
