Skull based tumors pose some of the most complex challenges in neurosurgery owing to their proximity to important structures such as optic nerves and arteries. For this reason, surgical planning heavily depends on high quality MR images. In this study we evaluated the performance of 7T imaging against standard scans at 3T and 1.5T for delineating such structures. Furthermore, the high-resolution scans were integrated in the neurosurgical workflow in order to evaluate improvements in surgical time and confidence of surgical decision-making.
