The Utility of 18F-DOPA-PET in the Treatment of Recurrent High-grade Glioma


About this study

This proposal is for a pilot study comparing volumes of 18F-DOPA-PET avidity with contrast enhancement and T2 FLAIR on MRI. We then plan to compare patterns of failure with target volumes, pre-treatment MRI changes and pre-treatment 18F-DOPA-PET.
