英文摘要:

Background The virtual reality (VA) system can provide the neurosurgeon to intuitively interact with and manipulate the three dimensional (3-D) image similarly to manipulate a real object It was seldom reported that the system was used in diagnosis and treatment of cerebral aneurysms This study aimed to investigate the application of VA system in diagnosis and therapeutic planning of cerebral aneurysms

Methods A total of 24 cases of cerebral aneurysms were enrolled in this study from 2006 to 2008, which diagnosed by 3-D digital subtraction angiography (3D-DSA) or VA-based computed tomography angiographies (CTA). The VR system and 3D-DSA system were used to observe and measure aneurysms and the adjacent vessels The data of observation and measurements were compared between VA image and 3D-DSA image. All the patients underwent surgical plan and simulated neurosurgical procedures in the VA system

Results There were 28 aneurysms detected in VR system and 3D-DSA system The VA system generated clear and vivid 3-D virtual images which clearly displayed the location and size of the aneurysms and their precise anatomical spatial relations to the parent arteries and skull The location, size and shape of the aneurysms and their anatomical relationship with the adjacent vessels were similar between 3-D virtual image and 3D-DSA, but the spatial relationship between aneurysms and skull only been displayed by VA system This VR system also could simulate simple surgical procedures and surgical environments.

Conclusions The VA system can provide a highly effective way to provide precise imaging details as same as 3D-DSA system and assist the diagnosis of cerebral aneurysms with virtual 3-D data based on CTA. It significantly enhances the chosen therapeutic strategy of cerebral aneurysms.
