Overview

In computer-assisted brain surgery, surgeons use imaging technologies, such as magnetic resonance imaging (MRI), intraoperative MRI, computerized tomography (CT) and positron emission tomography (PET) scans, to create a 3D model of your brain. This may be done before, or in some cases during, your surgery.

This model allows your brain surgeon (neurosurgeon) to plan the safest way to treat your condition. During your surgery, the computer system precisely guides your surgeon to the area(s) of your brain requiring treatment.

Why it's done

Computer-assisted brain surgery is used to treat a variety of conditions affecting the brain, including brain tumors, Parkinson's disease, essential tremor, epilepsy and arteriovenous malformations.

If you have a brain tumor, your surgeon may combine computer-assisted surgery with awake brain surgery.

Mayo Clinic neurosurgeons also use computer-assisted techniques to treat brain tumors, arteriovenous malformations, and other lesions with precisely focused beams of radiation using brain stereotactic radiosurgery.

If you have epilepsy, Parkinson's disease or essential tremor, computer-assisted surgery may involve deep brain stimulation. Your surgeons may use an MRI to help map your brain and plot the placement of the electrodes.
