Neuronavigation has become an established technology to provide objective data on localization in 3D space. In the surgery for lesions near the eloquent area, obtaining a functional image including functional magnetic resonance imaging fMRI and tractography is important for making presurgical planning. Navigation technology is essential to perform the operation according to the pre surgical planning. The surgeons, however, must realize that it does not always correlate well with real

Brain shift, caused by the loss of cerebrospinal fluid and tumor resection, is a major problem negatively affecting navigation accuracy. Intraoperative imaging to obtain updated anatomic image data overcomes the problem of brain shift, but the equipment is not so easily installed into the operating room. The development of computer technology is expected to solve this problem in the future. The following are some perspectives of neuronavigation with the advance of computer technology The 3D virtual image will be more intuitive to navigate for surgeons. The development of navigation workstations could have the potential to interpret the real surgical view and provide an automated nomenclature of brain structure to surgeons. Robotic systems might facilitate the navigation procedure to enhance the localization accuracy. Networked neuronavigation is a future direction to assist in operations performed at remote hospitals using navigation image software that utilizes network technology. Finally, to improve the navigation procedure amongst the operation team as well as surgeons, environmental navigation could be proposed to monitor the operative staff and to show the optimal arrangement in the operating room.
