Abstract:
Objective To evaluate the usefulness of virtual reality technique in preoperative planning of neurosurgery.Methods Multiple medical imaging data including magnetic resonance imaging,magntic rsonanc angiograph,magnetic resonance venography and computed tomography collected from 26 patients who suffered craniocerebral diseases,were transfered to Dextroscope system.A stereoscopic 3-D object displayed after merging,extracting,dissecting the data with the Radiodexter software in virtual reality environment.A suite of 3-D tools accessible inside the Dextroscope workspace enabled users to obtain measurement and simu- lated intraoperative viewpoint about the lesion and adjacent anatomic structure.A preoperative plan was de- fined and compared with real operation.Results 3-D stereoscopic virtual reality images of 26 cases were re- constructed successfully,and of coincidence with real situation in operations.Conclusion VR technique in Dextroscope system can integrat multiple medical imaging data quickly,intuitively and overall,offer a compre- hensive information about the lesions and related local anatomy,give a hand to optimizing the operative project and might be possible potentially to increase the safety of operation and the resecting rate of the lesion.
