Gamma Knife Center at Harborview

About this Clinic

Gamma Knife radiosurgery revolutionized the treatment of human brain diseases when it was introduced more than four decades ago. The UW Medicine Gamma Knife Center at Harborview offers the latest in Gamma Knife technology: the Perfexion and the Perfexion Extend system.

This minimally invasive radiosurgery technology treats patients with abnormalities that are located within the brain.  It is a one-day, outpatient procedure that requires little or no anesthesia, offers a fast recovery time and is safer and less costly than surgery or whole-brain radiation.

Over 500,000 Gamma Knife procedures have been performed worldwide since the technology first became available in 1968. It is used to treat blood vessel problems, such as arteriovenous malformations or AVMs, brain tumors, including  acoustic neuromas, meningiomas, pituitary tumors, cancers that originate in the brain, and cancerous lesions that have metastasized from distant areas of the body. It may be used to treat lesions that are close to critical structures. A small percentage of patients are treated to relieve functional disorders such as unmanageable pain, tremor and epilepsy.

Since 2000, the Gamma Knife Center at Harborview has treated more than 2000 patients.

Why We Charge for Parking
The Washington State Legislature and King County mandates that parking at Harborview be self-supporting. As a King County-owned, state-managed institution, all garages and parking lots on our campus are paid for out of parking revenues. Harborview parking revenues must pay for all repairs, bonds and loans on all parking facilities. Parking revenues are also used to subsidize various Harborview commuter programs and the valet service. According to the state legislature, parking revenues must pay for all these expenses and may not come from other sources.
