What is Gamma Knife surgery?

Gamma Knife radiosurgery uses focused radiation to target brain and pituitary tumors, arteriovenous malformations (AVMs), acoustic neuromas and other conditions.

No knife or scalpel is used. Our Gamma Knife Center offers safe, effective, one-day Gamma Knife radiosurgery.

UVA is the first center in Virginia to use Gamma Knife Icon, which offers even more accuracy, precision and safety than previous models.
