Gamma Knife - Ask Dr how old the rods are in the machine


#1

Hello - I’ve had GK twice for my cerebral AVM. The second time I had GK, the “rods” in the Lars Leksell machine had just been replaced. The procedure was so much shorter which meant less time in that “halo.” Would also suggest trying to be the first person scheduled. My experience in terms of pain during GK is directly related to how much time you are in the halo - the pressure literally builds up throughout the day as you move from MRI to Angio and then into the GK machine.
