Gamma Knife Radiosurgery

  • What is Gamma Knife Radiosurgery?

    Gamma knife radiosurgery uses gamma rays to treat brain tumours and other brain abnormalities without the need for invasive surgery. A stereotactic frame (investigative probes) is placed on your head, and an MRI scan and a cerebral angiogram (x-ray to view blood vessels in the brain) are performed before the surgery. These scans allow your surgeon to determine the dose of radiation needed to treat the diseased brain tissues while protecting the surrounding normal tissue from radiation damage. You will then be positioned in the gamma knife machine, where focused beams of radiation target the diseased brain tissues. Gamma knife surgery is a non-invasive procedure. It is very safe and precise, and is usually performed as an outpatient procedure.

  • Gamma knife radiosurgery is mainly used to manage and treat benign (non-cancerous) and malignant (cancerous) brain tumours. Radiosurgery can shrink the tumour or stop it from growing by damaging the genetic materials in tumour cells. It is also beneficial for the treatment of other brain abnormalities such as arteriovenous malformations (abnormal tangle of blood vessels) and trigeminal neuralgia (damaged nerve responsible for facial movement and sensation).
