To investigate the value of virtual imaging technique in diagnosis of intracranial aneurysms.
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.
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.
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.
探讨虚拟成像技术在颅内动脉瘤诊断中的价值。
本研究纳入54例经三维CT血管造影（3D-CTA）检查确诊的颅内动脉瘤患者。使用手术规划系统对原始CT图像进行三维重建，获取颅骨和脑血管的三维虚拟图像，从多个角度观察和测量动脉瘤的位置、大小、形态及其与相邻组织的解剖关系。所有患者均使用系统中的虚拟手术器械进行手术规划和模拟手术操作。
54例患者均成功进行了三维虚拟图像重建及手术规划操作。虚拟成像系统生成的三维虚拟图像清晰逼真，能清楚显示动脉瘤的位置、大小及其与载瘤动脉和颅骨的精确解剖关系。该虚拟现实成像系统还可模拟简单的手术操作。
基于虚拟现实成像的手术规划系统可作为辅助诊断的有用手段，提供颅内动脉瘤精确的成像细节。
