About Neurosurgery
Neurosurgery (or neurological surgery) is the medical specialty concerned with the prevention, diagnosis, treatment, and rehabilitation of disorders which affect any portion of the nervous system including the brain, spinal cord, peripheral nerves, and extra-cranial cerebrovascular system. Neuroradiology methods are used in modern neurosurgical diagnosis and treatment, including computer assisted imaging computed tomography (CT), magnetic resonance imaging (MRI), positron emission tomography (PET), magnetoencephalography (MEG), and the stereotactic surgery.

Neurosurgery
Neurosurgery (or neurological surgery) is the medical specialty concerned with the prevention, diagnosis, treatment, and rehabilitation of disorders which affect any portion of the nervous system including the brain, spinal cord, peripheral nerves, and extra-cranial cerebrovascular system.
Minimally invasive endoscopic surgery is utilized by neurosurgeons. Techniques such as endoscopic endonasal surgery are used for pituitary tumors, craniopharyngiomas, chordomas, and the repair of cerebrospinal fluid leaks.
Virtual Reality
Virtual Reality is revolutionizing the way we plan for, rehearse and perform brain surgery – making surgery safer and more effective. For the first time ever, patients are able to see inside their own brains in order to truly understand the surgical plan and risks. This allows our patients to take charge of their own health and be part of the team that is working to make them better
Dr. Robert Louis, director at Hoag, and Danielle Collins, chief experience officer at EMPOWER360, discuss how virtual reality technology can empower patients to become a member of their own healthcare team.
