Gamma Knife Surgery

Gamma Knife stereotactic radiosurgery is a technique that utilizes 201 separate beams of gamma radiation energy, all precisely directed at a single point. The Gamma Knife is used to treat benign and malignant brain tumors, as well as other brain disorders. Gamma Knife radiosurgery combines modern methods in neuroradiology (MRI, CT and cerebral angiography) with sophisticated computer technology to localize and target brain lesions with gamma rays. The precise targeting of Gamma Knife radiation in a single large dose makes it as effective as conventional surgery for certain brain conditions, but with potentially fewer serious risks.

The Gamma Knife Center at Roswell Park is a major community-based resource for the application of state-of-the-art radiosurgery in Western New York. Treatment is provided by our neurosurgeons as well as radiation oncologists and neuroradiologists working together as part of UBNS’ multidisciplinary brain tumor team.

Brain tumor treatment is highly individualized. Although not appropriate for everyone, many patients benefit from having stereotactic radiosurgery as part of their overall treatment plan.

The main tumor types that are potentially treatable with Gamma Knife stereotactic radiosurgery include:

• Metastatic brain tumor
• Gliomas
• Meningiomas
• Pituitary tumors
• Craniopharyngiomas
• Skull Base Tumors
