Limitations
MINOR, BRAIN TUMOR
The major limitation of our study is the low number of participants. A further drawback of the study design is that we did not perform a 1:1 randomization to either conventional or stereoscopic visualization, as we wanted to avoid any legal issues to due lack of conventional patient consent. In this context, we also observed an imbalance in age and education between both groups; however, this was not statistically significant. One minor pitfall was that the imaging navigation had to be controlled by a study staff member, as the 3D mouse is difficult to use. However, during the implementation of the study, patients were impressed by and appreciated the modern form of individual visualization and the reported evaluation provides the first insights into using stereoscopic visualization in neurosurgical consent conversations for brain tumor patients.
