Conditions astrocytoma, oligoastrocytoma, oligodendroglioma
Sponsor Ludwig-Maximilians - University of Munich
Collaborator Deutsche Krebshilfe e.V., Bonn (Germany)
Start date June 2008
End date December 2015
Trial size 38 participants
Trial identifier NCT01089244, GGN-CP4


The aim of the study is to compare the two imaging modalities perfusion weighted MR-imaging and FET-PET in their ability to provide an accurate histological evaluation of low grade glioma and to reveal focal abnormalities within a homogeneously appearing tumor. Additionally, therapeutic effects should be assessed during a time period of two years.
