Cerebral Connectivity and Metabolic Phenotype of Gliomas: Prospective Addition of DTI and Rs-fMRI to a Preoperative FDG PET Strategy, With Neuropsychological Correlates and Post-treatment Follow-up

Starting soon · Not applicable

Conditions studied: Glioblastoma

In brief

The aim of this study is to determine whether the diffuse cerebral metabolic disturbances observed in glioblastoma are exclusively linked to the direct and indirect effects of tumor infiltration (particularly structural disconnection), or whether they also reflect a more global alteration of neurometabolic and neurovascular coupling mechanisms. This approach thus aims to better understand the pathophysiological basis of cognitive impairment in glioblastoma and to characterize the impact of the disease at the level of brain networks.
