Surgical impact on overall survival for IDH-mutant tumors is much more significant than IDH-wildtype tumors. Thus, the role of neuroimaging is different between these two diseases. It is crucial to predict the presence or absence of IDH mutation, as it has a significant influence on the surgical strategies of the tumor. On the other hand, it is still difficult to fully visualize the full extension of the disease for IDH-wildtype tumors, which hinders planning the most efficient radiotherapy. The author would like to provide an overview of the current standard treatment strategies for gliomas, referring to the role of neuroimaging.
