Gamma Knife® surgery is a well-established method to treat selected targets in the brain; but it is not a knife. Instead, highly focused beams of radiation are directed to the treatment area in the brain.
The shape and dose of the radiation is designed to hit only the target without damaging surrounding healthy tissue. Gamma Knife® offers safe and effective treatment for more than 75,000 patients worldwide every year. The treatment procedure is simple, painless and straight forward.
Gamma Knife® Centre of Queensland at the Princess Alexandra Hospital treats the following conditions:
Your doctor will inform you about the entire procedure. Gamma Knife® treatment does not require cutting or shaving of your hair.
A key component in Gamma Knife® is the headframe which allows the doctor to accurately pinpoint the target to be treated in your brain. This lightweight frame, which is attached to your head with four pins, prevents your head from moving during imaging and treatment procedures. Local anaesthetic is applied where the pins are to be attached.
After the head frame is in place, magnetic resonance imaging (MRI) and computed tomography (CT) will be done to determine the exact size, shape and position of the target in the brain.
The imaging allows your physician to develop a precise and accurate treatment plan. Each treatment plan is unique and every patient’s plan is individually designed to address the specific medical condition. The doctor and other clinicians in radiation oncology plan your treatment on the computer and calculate how it will be delivered.
After planning, your actual treatment can start. You will lie down on the treatment couch and the head frame will be fixed to the Gamma Knife®. You are awake during the procedure and will be able to communicate with your team through an audio connection. The couch moves into the circular dome and commences your silent and painless treatment which will last from a few minutes to more than an hour depending on the size of the treatment target. The team will monitor the treatment at all times.
The head frame will be removed. Some patients may experience a mild headache or minor swelling where the frame was attached but this is temporary. Your doctor will tell you whether you can go home and return to normal routines or whether your treatment plan involves an inpatient stay.
On discharge, the nurse will provide you with the details of your follow-up appointments which will depend on the condition treated.
