Abstract
Objective To investigate the contribution of high-field intraoperative magnetic resonance imaging(iMRI)for complete resection in glioma surgery.Methods From February 26,2009 to June 15,2009,40 patients of gliomas who underwent craniotomy were investigated retrospectively.The complete resection of tumors and volumetric analysis were assessed with intraoperative imaging data.Results Only10 patients were revealed complete tumor resection after first iMRI scan,and the operations were continued to remove residual tumors in 23 patients.The complete tumor resection was confirmed in 21 patients.Complete resection Was achieved finally in 78% of all patients,comparing to the initial 25% after first iMRI scan.The residual tumor volume was significantly reduced in subtotal removal patients.Conclusion The application of hish-field iMRI is helpful for complete resection in glioma surgery. Key words: Glioma; Intraoperative magnetic resonance imaging; Tumor volume; Complete resection
