As patients with WHO IV° gliomas are still having a dismal prognosis, further tumor characterization is needed. With prognosis and histopathological parameters being dependent on tumor localization, and Chemical-Exchange-Saturation-Transfer(CEST) MRI at 7T being one of the latest advances in tumor imaging, we have prospectively evaluated CEST signals in 21 patients. Amide CEST and ADC parameters are significantly different with regard to brain hemispheres and correlating. CEST NOE(Nuclear Overhauser-Effect) is not different with regard to brain hemispheres, but in case of contact to the subventricular zone, which is accompanied by worse prognosis. NOE is possibly showing complementary information to Amide CEST.
