双源CT对面神经管的显示及其临床应用价值

目的：探讨双源CT图像后处理技术对面神经管的显示能力及其在面神经管病变中的临床应用价值.材料与方法：回顾性分析30例正常人与12例患者的双源CT面神经管曲面重建（CPR）图像与多平面重建（MPR）图像,并对30例正常人双侧面神经管各段进行测量.结果：30例正常人的面神经管迷路段在轴位扫描图像上显示最佳,面神经管垂直段在矢状位重建MPR图像上显示最佳.曲面重建图像可同时显示双侧面神经管.12例患者中有11例能良好显示病变段面神经管.结论：双源CT图像后处理技术对面神经管的显示具有较高的准确性,对面瘫的定位诊断具有重要指导意义.

The Display and its Clinical Application Value of the Facial Neural Tube on Dual-source CT

Purpose： To investigate the dual-source CT image processing technique on facial nerve tube display ability and the clinical application value in the facial nerve canal pathology. Materials and Methods： A retrospective analysis of the facial nerve canal curved planar reconstruction （CFR） images and multi-planar reconstruction （MPR） images of 30 cases of normal persons and 12 patients with dual-source CT, and double facial nerve tube sections of the 30 cases of normal human are measured. Results： 30 cases of normal human facial nerve canal fan sections in axial scan images showed the best, vertical segment of facial nerve canal in sagittal reconstruction of MPR images showed the best. Curved planar reconstruction image can be displayed at the same time double facial nerve tabe. In 12 cases, 11 cases showed the lesion can be good segment of facial nerve canal. Conclusion： Dual-source CT image processing technique on facial nerve tube display with higher accuracy, facial paralysis diagnosis has important guiding significance.
