In the case of radiosurgery, no incision is made, and you are not sedated. The word radiosurgery is used because the treatment has the same effect as surgical procedure.
- You have to be nil-by-mouth when you come to the hospital.
- It is best to leaven jewellery and other metal object at home.
- Make sure there is something who can take you home after the radiation. You are not allowed to drive a car on the day itself.
1. Positioning metal frame
- It is vital that you do not move your hear during the radiation.
- To achieve this, a metal frame will be placed around your head.
- The metal frame will be secured to your skull:
- Under local anaesthetic
- With 4 little screws in the skull
- No hair will be shaved off
- Keep your head still during the CT scan and the radiation
- You will feel some extra pressure when the frame is secured to your head. This pressure will go away after a few minutes.
- As soon as the frame has been secured, the CT scan will be made.
- After the CT scan you are allowed to eat and drink.
- The CT images will be processed in order to determine the radiation as accurately as possible.
2. The radiation
- The radiation will approximately take one hour.
- It's best to go to the toilet before the radiation.
- You take your position on the radiation table.
- Via the metal frame you will be secured to the table, so that your head can't move during the radiation.
- A radiation machine will turn a couple of times around your head to accurately radiate the required area.
- The radiation does not hurt.
- You will hear a buzzing noise.
- After the radiation, the metal frame will be unscrewed.
- The wounds of the screws will be disinfected and covered with plasters.
