Gamma Knife® Radiosurgery
Gamma Knife radiosurgery is one of the most precise, powerful, and proven treatments for brain disorders. This painless procedure uses hundreds of highly focused radiation beams to target tumors and lesions within the brain.
With no surgical incision required, Gamma Knife radiosurgery is especially useful when conventional surgical procedures pose a high risk for patients.
Pioneers in Gamma Knife Treatment
UPMC installed the first North American Gamma Knife in 1987 and subsequently introduced and pioneered each succeeding generation of technological improvement. Over its 25-year history at UPMC, Gamma Knife radiosurgery has proved effective for nearly 12,500 patients with:
- Benign or malignant brain tumors
- Vascular malformations
- Other functional problems
Today, the Center for Image-Guided Neurosurgery at UPMC is the nation’s leading provider of Gamma Knife procedures, and is a major teaching center for neurosurgeons, radiation oncologists, and medical physicists from around the globe.
Conditions We Treat With Gamma Knife Radiosurgery
Our experts in Gamma Knife radiosurgery are able to treat an array of brain disorders.
||Results After Gamma Knife Treatment:|
||Treatment damages the genetic material in the tumor's cells, resulting in their inability to reproduce. Following treatment, the cells die and the tumor may gradually shrink.|
||Treatment causes blood vessels in the AVM to thicken and close.|
||After treatment, a lesion gradually forms in the nerve and blocks the transmission of pain signals along the nerve.|
||Treatment can reduce the size or limit the growth of the tumor with little risk of permanent nerve damage|
|Pituitary and Skull Base Tumors
||Treatment can shrink the tumor and lessen the disruption of pituitary hormone regulation.|
How Gamma Knife Radiosurgery Works
- Before the procedure, a team of our Gamma Knife experts creates a detailed map of your brain, precisely pinpointing the tumor or lesion.
- During the procedure, a focused, custom-designed dose of radiation targets only the diseased tissue, leaving the surrounding healthy tissue intact.
- Generally, patients only need one treatment to begin experiencing gradual improvements in their condition, over the course of a few months.
