摘要结论：与X线平片相比，计算机断层扫描（CT）扫描和内耳三维（3D）重建提供了耳蜗管内电极关系的更准确图像，直接显示了耳蜗内电极插入深度。目的：本研究旨在评价螺旋CT扫描和3D重建在确定植入式人工耳蜗电极的插入部位和深度方面的价值。方法：对172例人工耳蜗植入者进行研究。所有患者均行X线平片检查植入电极，157例人工耳蜗植入者行螺旋CT扫描，轴位1mm层厚。将CT扫描的数据传输到工作站进行内耳的3D重建（直接容积再现）。电极显示采用假彩色技术。结果：X线平片可间接评价电极插入深度。相比之下，内耳三维重建CT扫描的立体图像更准确地显示了电极的形状、位置和插入深度。
Abstract Conclusions: Computed tomography (CT) scan with three-dimensional (3D) reconstruction of the inner ear provides a more accurate image of the relationship of the electrode within the cochlear canal, with direct demonstration of electrode insertion depth in the cochlea in comparison with X-ray plain film. Objective: This study was designed to evaluate the value of spiral CT scans with 3D reconstruction in determining the insertion site and depth of implanted cochlear implant electrodes. Methods: A total of 172 cochlear implant recipients were involved in this study. The implanted electrodes of all patients were examined by X-ray plain film, and 157 cochlear recipients were examined by spiral CT scans with axial 1 mm image slices. The data from the CT scans were transferred to a workstation for 3D reconstruction (direct volume rendering) of the inner ear. The pseudocolor technique was used to display the electrode. Results: The insertion depth of the electrode could be evaluated indirectly by the X-ray plain film. In contrast, the stereoscopic images from a CT scan with 3D reconstruction of the inner ear demonstrated the shape, position, and insertion depth of the electrode more accurately.
