Objective: VP Reveal (Vesalius Perfectus, Eindhoven, The Netherlands) is a commercially available “virtual reality” system designed to generate and review stereoscopic 3D models of any DICOM based CT, MRI, MRA, PET-scan within seconds. The system uses polarized 3D glasses and a 3D monitor. No wearable electronic devices are needed. The objective of our study is to explore the value of the new system in brain tumor surgery.
Method: The usefulness of the system was evaluated in 20 patients with brain tumors. In the following we will describe our experience with the system in 5 different patients. Two patients with a glioblastoma, one patient had an anaplastic oligodendroglioma, one patient with a plexus tumor and one patient with a vestibular schwannoma. We reviewed all cases preoperatively using the stereoscopic display system to enhance our 3D imagination of the tumor and to plan the surgical approach. We further compare the intraoperative findings with the preoperative plan.
Results: In all cases the generated 3D models of the preoperative MRI matched precisely the intraoperative findings and the surgeon had an enhanced imagination of the tumor location, tumor size and required craniotomy. Additionally, the VP Reveal system was extremely beneficial in delineating the tumor margins in a high resolution and the relationship to functional structures when the 3D model was fused with diffusion tensor imaging (DTI) or functional MRI. The stereoscopic visualization in 3D of the patient data was unique, high res and as detailed in 3D as the original 2D-slice data. Most importantly, the visualization was seamless, manipulation with the 3D model was lag-free even in high resolution. Approximately 2 minutes were needed to import raw DICOM data into the system and generate the model.
Conclusions: Our results are promising and suggest that the VP Reveal system is a useful and reliable 3D imaging tool in preparing the resection of brain tumors using conventional patient scan data. It has multiple functionalities that can be tailored to suit the procedure and the experience of the surgeon.
