It is hoped the scanner will enhance surgeon's knowledge of neuroscience
A £3m scanner, which helps surgeons to safely and completely remove tumours in children, has been unveiled at Alder Hey hospital in Liverpool.
Understood to be the first of its kind in Europe, the new technology enables scans to be carried out in the operating theatre during surgery.
It will also reduce the number of times a child has to be anaesthetised and minimise their exposure to radiation.
The money was raised by the hospital's charity, Imagine Appeal.
Medical director Dr Steve Ryan said: "We are tremendously excited by the potential for this outstanding facility which is one of only two dedicated paediatric units in the world.
"We pride ourselves in offering world-class care and this is the newest application to further push the boundaries in both diagnostics and neurosurgery."
The machine provides the surgeon with highly accurate, real-time information used for navigation during operations and updates on their progress.
