Optimizing costs of intraoperative magnetic resonance imaging. A series of 29 glioma cases.

Purpose: The goal of this study was to develop a method to reduce the costs of intraoperative high-field magnet resonance imaging (iMRI). The results of a series of 29 gliomas removed with this technique are presented.

Methods: A series of 29 patients with brain gliomas were operated on using a low-cost method of high-field intraoperative MRI (Signa 1.
