Abstract: Objective To study the initial application of 3.0T high field intensity intraoperative magnetic resonance(iMR)for cranial tumors.Methods Forty-three patients with cranial tumors including 23 glioma cases,12 pituitary tumor cases,3 brain stem cavernous hemangioma cases,2 meningioma cases,2metastatic tumor cases,1 neurilemmoma case,received operation examined with GE Signa HDX 3.0T iMR system.The operation process and influence of iMR were reviewed.Results In 43 patients,average iMR examination was 1.3(1-3)times.In 16 patients the first iMR examination revealed tumor remnants,and in 13 of them continued surgical interventions and complete resection.The rate of complete resection was increased from 63％(27/43)to 93％(40/43).No complications related to iMR occurred.Conclusion 3.0T high field intensity iMR can provide accurate positioning and real-time navigation for the surgery,increase the rate of complete resection,improve the accuracy and safety of cranial tumor resection,and decrease complications.
