The purpose of this exhibit is: To illustrate the spectrum of imaging findings of GBMs, and to discuss protocol of preoperative examination, especially focused on MR images. To learn common and unusual manifestations; such as infratentorial location, secondary GBM, multifocal GBM, paucity of contrast enhancement, marked cystic degeneration, massive bleedings mimic intracerebral hemorrhage. To learn recent application of advanced techniques to GBM, such as diffusion kurtosis imaging, ASL, and etc. The major teaching points of this exhibit are: Each unusual manifestations of GBM, such as multifocal, secondary, mainly cystic, massive hemorrhage, and poor enhancement visualized in approximately less than 5% of the patients. It is important to make a correct diagnosis of GBM complementary usage of MRS, diffusion, and perfusion imaging.  

Introduction General aspects of GBM Protocol of MRI for pretreatment of GBM Location of GBM Multifocal GBM Primary vs. secondary GBM Gd enhancement of GBM T2 prolongation & diffusion restriction of GBM Secondary degeneration of GBM MR spectroscopy Diffusion tensor imaging/ DKI and other diffusion MR metrics Perfusion imaging: DSC, ASL and pearmeability 18F-FDG vs. 11C-MET PET
