About Gamma Knife

The Gamma Knife Perfexion, a non-invasive stereotactic radiosurgical tool, is an alternative or supplemental treatment to traditional brain surgery. Gamma Knife is used to precisely target malignant and benign brain tumors and disorders with finely-focused radiation beams that minimize damage of healthy brain tissue. The procedure typically is performed in a single outpatient treatment session with considerably reduced treatment times and minimized surgical complications.

Gamma Knife utilizes the latest advanced diagnostic imaging and three-dimensional treatment planning software to deliver 192 finely-focused beams of gamma radiation to small targets inside the brain. The beams converge at a point to treat the affected tissue, while minimizing the damage of healthy brain tissue. 

Conditions Treated

  • Malignant Tumors: metastatic tumors (cancer spread to the brain), gliomas, chondrosarcoma
  • Benign Tumors: acoustic neuromas (vestibular schwannomas), meningiomas, pituitary adenomas, low grade glioma and skull based tumors
  • Vascular Abnormalities: arteriovenous malformations (AVMs), cavernous angiomas (cavernous malformations
  • Functional Disorders: trigeminal neuralgia (also known as tic douloureux or chronic facial pain)

Candidates Treated

  • Patients with brain tumors
  • Patients with vascular disorders
  • Patients who are not candidates for conventional neurosurgery or radiation therapy
  • Additional therapy for patients who have already undergone surgery, chemotherapy or radiation and require further treatment
  • Gamma Knife Perfexion may also be recommended for patients with these conditions: 
    Tumors or vascular malformations that are surgically inaccessible
    Risk factors that make surgery inadvisable
    Need for an additional dose of radiation following radiation therapy
    Recurrent tumors
    Facial Pain

Gamma Knife therapy may also be suggested as an adjunct to standard neurosurgical therapy or as the preferred course of treatment when further traditional therapy is not recommended.
