Radiogenomic and Prognosis Analysis in Glioma

Previous studies have proposed certain imaging characteristics correlating with genetic, molecular and expression patterns. Advanced imaging provides additional clues but no studies have examined its added value particularly in a prospective setting. The investigator's aim to evaluate preoperative MRI for patients suspected of glioma to predict IDH mutation, 1p19q codeletion, MGMT methylation and EGFR mutation status using imaging characteristics such as margin, patterns of contrast enhancement and edema as well as diffusion and perfusion characteristics. This will be confirmed pathologically and further correlated with patients' long term outcome.
