A retrospective analysis of survival after resection of glioblastoma was performed comparing use of intraoperative MRI with conventional surgery. There was a significant difference in extent of resection, with more gross total resections achieved with iMRI. There was a significant improvement in overall survival at 6 months with iMRI. The groups had equivalent survival from 12-36 months. Younger age was correlated with longer overall survival.
