Primary Brain TumorsThe ONS neurosurgical team provides comprehensive surgical management of patients with a variety of brain, spine, and peripheral nerve tumors using the latest in intra-operative neuro-navigation. In the operating room, high resolution MRI images are used to create a 3-D visual reconstruction of the patient’s brain, which is then used as a map of the brain. This system acts like GPS for the brain and helps guide the surgeon to safely and completely remove the tumor. When necessary, intra-operative brain mapping of functional cortex may also be done.
