MR imaging is an integral part of the management of gliomas. Morphologic and functional MR imaging modalities help in the assessment of location and extent of the tumor and of its biologic activity. techniques and imaging findings of WHO II, III and IV gliomas at structural (high-resolution T2W, Flair, MPR, SWI) as well as at functional (DWI and DTI, MR Spectroscopy, dynamic susceptibility-weighted contrast-enhanced MR perfusion, arterial spin labeling) MR imaging will be summarized. In particular, the predictive value of multimodality MRI in detecting anaplastic transformation and the Value of multimodality MRI in detecting pseudoprogression and pseudoresponse will be emphasized. The major teaching points of this presentation are: 

1. understanding the spectrum of key image characteristics of glioma at various 3T MR techniques. 2. conjoint interpretation of structural and functional MR imaging findings helps in recognizing glioma grade, tumor tendency for progression (upgrading) and tumor response after therapy. 3. choosing a multimodality MRI approach assists biopsy and surgery planning.
