Introduction. Volume of glioma resection positively correlated with treatment results. Advance in extent of resection due to various additive methods leads to prolonged overall survival and delays progression. Our aim was to evaluate the value of intraoperative magnetic resonance imaging.Objective – to present the first experience of using intraoperative magnetic resonance imaging and evaluate the effectiveness and safeness of this technique in surgery of glial brain tumors.Material and methods. Prospective analysis of surgical interventions performed using the intraoperative magnetic resonance imaging and the results of neuroimaging in 9 patients with different grade brain gliomas treated in Federal Brain and Neurotechnology Center was carried out.Results. In all patients we detect variable residual tumor volume after first resection. Additional resection was performed in all cases after the intraoperative magnetic resonance imaging. Mean scan time were 45 minutes overall time for scan were decreasing as we gain experience in using intraoperative magnetic resonance imaging.Conclusion. Intraoperative high-field intraoperative magnetic resonance imaging can be successfully used in the surgery of brain gliomas. The technique allows increasing the radicality of tumor removal without increasing the risk of complications.
