摘　　要：目的探讨虚拟影像手术计划系统在颅内动脉瘤诊断中的应用价值。方法选择54例经3D-CTA检查确诊的颅内动脉瘤患者,通过虚拟影像手术计划系统对原始CT图像进行三维重建,获得颅骨及脑血管的三维立体虚拟影像资料。对动脉瘤的位置、大小、形态及毗邻结构进行多角度观察和测量。利用系统的模拟手术工具对每例患者进行手术计划和模拟手术操作。结果54例均成功地进行了三维立体虚拟影像重建和相关操作,该系统形成的虚拟图像清晰、逼真,可非常直观地显示动脉瘤的位置、大小、与载瘤动脉和颅骨的关系。利用该系统可进行简单的手术模拟操作。结论虚拟影像手术计划系统可作为颅内动脉瘤的辅助诊断工具,利用该系统可获得更详细的动脉瘤影像学信息。Objective To investigate the value of virtual imaging technique in diagnosis ofintracranial aneurysms. Methods Fifty-four cases of 54 intracranial aneurysm diagnosed by three-dimensional CT angiography （3D-CTA） examinations were enrolled in this study. Three-dimensional virtual images of the skull and cerebral vessels were acquired by three-dimensional reconstruction of the original CT images using the surgical planning system, and the location, size and shape of the aneurysms and their anatomical relationship with the adjacent tissues were observed and measured from several angles. All the patients underwent surgical planning and simulated surgical operations using the virtual surgical instruments available in the system. Results All the 54 cases had successful three-dimensional virtual image reconstruction and the surgical planning operations. The virtual imaging system generated clear and vivid three-dimensional virtual images which clearly visualized the location and size of the aneurysms and their precise anatomical relations to the parent arteries and skull. This virtual reality imaging system also allowed simulation of simple surgical procedures. Conclusion The surgical planning system based on the virtual reality imaging can serve as a useful means to assist the diagnosis and provide precise-imaging details of intracranial aneurysms .
