Gamma Knife® Radiosurgery

Gamma Knife® radiosurgery is a non-invasive treatment that delivers many small beams of radiation to a precisely defined target in the brain. Each beam has a low individual dose, but together they focus high energy where it is needed while minimizing exposure to healthy tissue.
Many conditions are treated in a single session; depending on tumor size and location, some treatments may be divided into multiple doses.
Sometimes referred to as “surgery without the knife,” Gamma Knife® radiosurgery minimizes the damage to surrounding healthy tissue. With Gamma Knife® radiosurgery, patients experience little discomfort, and having no incision eliminates the risk of bleeding and infection. With reduced side effects, you can return more quickly to your daily activities.
Gamma Knife® radiosurgery provides innovative care for the following conditions:
- Acoustic neuroma/schwannoma
- Epilepsy
- Glial tumors
- Meningioma
- Metastatic brain tumors
- Movement disorders, including Parkinson's disease
- Oligodendroglioma
- Pituitary tumors
- Primary brain tumors
- Trigeminal neuralgia
- Vascular disorders, including arteriovenous malformations (AVMs)
