Optimizing brain tumor resection: Low-field interventional MR imaging

In this article, the authors describe their strategy for intraoperative MR image guidance of tumor resection at low-field (0.2 T) strength. It is their opinion that intraoperative imaging is most useful in assessing the resection of intrinsic, infiltrating brain tumors; boundaries of the tumor cannot be clearly distinguished with the surgeon's eyes, and therefore, this discussion predominantly applies to the surgical resection of gliomas.
