Radionecrosis and FDG PET

“Radionecrosis and FDG PET”
Gliomas are the most common malignant primary central nervous system (CNS) tumours. When high-grade gliomas (HGG) recur, subsequent magnetic resonance (MRI) imaging, with additional sequences is required.The Positron Emission Tomography (PET) radiotracer [18F]-fluorodeoxyglucose (FDG) will be used in this study to distinguish between changes seen on MRI which can be a reflection of pseudoprogression, radiation necrosis, or recurrence.

Positron Emission Tomography Imaging
Participants will receive an intravenous injection of 250 MBq (megabecquerels) of 18F-Fluorodeoxyglucose (18F-FDG). The first Positron Emission Tomography (PET) acquisition of the head will occur one hour post-injection. The second acquisition will take place 3 hours post-injection. Both early and late PET images will be manually co-registered with the participant's most recent magnetic resonance images.
