Comprehensive, compassionate outpatient brain disease treatment

Located at Harborview Medical Center, the Gamma Knife Center is dedicated to making your treatment as comfortable as possible.

Gamma Knife radiosurgery is a noninvasive or minimally invasive outpatient treatment. It is an option for some patients with conditions that would typically require brain surgery or whole-brain radiation. It is used to treat blood vessel problems, such as arteriovenous malformations (AVMs), and brain tumors, including acoustic neuromas, meningioma, pituitary tumors, cancers that originate in the brain and cancerous lesions that have metastasized from distant areas of the body.

We can often schedule you for consult and treatment using the latest Gamma Knife Icon system, which uses both mask- and frame-based options, within 1-2 weeks, and we expedite appointments for urgent situations.

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.
