The Region’s Only Gamma Knife® Perfexion™

For more than 30 years, Gamma Knife® has been the gold standard in radiosurgery, offering a safe, precise option for treating malignant and benign conditions of the brain. Gamma Knife® Perfexion™ can treat even more—and harder to reach—tumors, and Lehigh Valley Hospital-Cedar Crest is the first in the area to offer this sophisticated technology.

Radiosurgery with Gamma Knife Perfexion does not actually involve a knife. It’s an exceptionally precise treatment method that delivers extremely focused radiation beams to selected targets. In addition to targeting brain tumors and lesions, Perfexion is capable of treating vascular malformations, as well as lesions in the sinuses, eye sockets and upper spine and neck.

This innovative system offers faster setup and treatment of one or more tumors in a single session, which offers patients the following benefits:

Faster treatment

• Treatment sessions last only 20-60 minutes, and the entire procedure, including setup and pre-testing, only takes 1-4 hours, depending upon the number of targets.
• Most patients return to their daily routine in a day or so.

Safer and more precise

• Radiation shielding levels are 10 times better than alternative technologies.
• The size and shape of the radiation source—Cobalt 60—is optimized to hit only selected targets, without damaging surrounding tissue.
• Since no incisions are made, the risk for complications is low and side effects are rare and mild.
