Gamma Knife Radiosurgery for Glioma & Astrocytoma

Doctors at NYU Langone’s Perlmutter Cancer Center may use Gamma Knife® radiosurgery to manage low-grade and high-grade glioma tumors or as an alternative to craniotomy in people who are not able to have surgery. After a doctor evaluates your imaging studies, he or she creates a customized treatment plan based on the size and location of the tumor.

Gamma Knife® radiosurgery is a well-established form of stereotactic radiosurgery, a noninvasive treatment for brain tumors, blood vessel malformations, and other neurologic disorders. It does not require a surgical incision to reach the tumor.

Stereotactic radiosurgery uses MRI scans or another form of high-resolution brain imaging to create a three-dimensional image of the targeted area of the brain. This area is then treated with many small beams of radiation, which destroy cancer cells.

The Gamma Knife® Icon used by doctors at Perlmutter Cancer Center is the newest, most sophisticated device for stereotactic radiosurgery. It features a flexible delivery system, which enables doctors to administer doses to one or more areas of the brain. Our team of doctors can treat multiple brain lesions during a single session.

Our experts are skilled at using Gamma Knife® radiosurgery, a noninvasive treatment for brain tumors.

Because radiosurgery involves delivering precise therapy, a person needs to wear a head frame to remain still. Our doctors ensure the frame is as comfortable as possible throughout the treatment.
