Penn Gamma Knife® Center

Gamma Knife® radiosurgery is a powerful, precise, blade-free surgical option for patients suffering from brain tumors and other serious brain disorders. Requiring no incision, Gamma Knife is a safe, non-invasive treatment.

Cutting-edge Brain Surgery that's Blade-Free

Gamma Knife radiosurgery delivers more than 200 precise radiation beams that converge deep within the brain to shrink or even destroy diseased or damaged tissue. Alone, each of the beams contains harmless doses of radiation so surrounding tissue remains unaffected, protecting the important functions of the brain. Gamma Knife technology has a proven track record as an effective alternative to traditional brain surgery.

Pennsylvania Hospital is home to the Penn Gamma Knife Center. The Gamma Knife team recently treated its 1,000th patient making it one of the most active Gamma Knife centers in the region.

The Penn Gamma Knife Center treats patients with a wide variety of conditions including:

Gamma Knife treatment offers new hope to patients with a variety of deep-seated brain lesions and arteriovenous malformations once considered inoperable. In addition, the Penn Gamma Knife Center is among the few centers in the country treating benign and malignant tumors of the anterior, middle and posterior cranial base with the technology.

Gamma Knife radiosurgery lowers the risks that can be experienced with traditional surgery while minimizing patient discomfort. Patients are not given general anesthesia and remain awake throughout the entire procedure. Patients are in constant audio and visual communication with the medical team. The treatment is usually complete after a single procedure and patients return home the same day.

At Philadelphia's busiest Gamma Knife center, Penn Medicine neurosurgeons, neuroradiologists, otorhinolaryngologists (ENT), radiation oncologists and medical oncologists work together to tailor an individualized pre- and post-treatment plan in order to meet the unique physical and emotional needs of each patient in a caring, professional environment.
