Survival is for many brain tumours related to how much of the tumour is removed during surgery. The methods and technology developed in Trondheim facilitates more complete resection of brain tumours, while preserving normal functionality. For low grade gliomas it has been shown that early radical resection with intraoperative 3D ultrasound results in better survival, than using a watchful wait-and-see approach [1]. Importantly this survival benefit can be achieved with low morbidity, preserving normal function and long-term quality of life in most instances. Image-guided surgery with the aid of intraoperative 3D ultrasound, as used in Trondheim, is therefore a useful tool for achieving safe and effective brain tumour surgery.
