Assessment of biological features of malignant brain tumor by means of non-invasive image modality is required in the field of neurosurgery. Previous studies have challenged this issue by looking into individual data obtained from multimodal neuroradiological assessments. In this research, we have attempted to integrate DTI-MRI and 11C-methionine PET data to compensate each other to determine the cut-off values for discriminating normal and abnormal tissues. We believe that our findings will benefit the understanding and interpretation of malignant brain tumor imaging on DTI and 11C-methionine PET.
