Microsurgery in brain tumor patients aim to complete tumor resection without compromising neurological functionality. Inadequate preoperative knowledge of tumor may prolong surgical time and increase risk of postoperative complications which may depends upon tumor-brain adhesion and tumor stiffness. Previous studies have only looked into adhesion and stiffness separately using Magnetic Resonance Elastography (MRE). Previously, we proposed both adhesion and stiffness in vestibular schwannoma patients. Aim of this study is to also include meningioma cases in the analysis in order to broaden the tumor types and complexity. Preliminary results show good correlation between MRE-derived preoperative assessment of tumor and surgical findings.
