abstract = {The aim is to explore the concept of photopenic defects in
newly diagnosed glioma patients with the 2 widely used
11C-MET and 18F-FDOPA PET amino acid tracers. Thirty-two
11C-MET and 26 18F-FDOPA PET scans with amino acid
PET-negative gliomas were selected in this European
multicentric study. Of these gliomas, 16 11C-MET and 10
18F-FDOPA PET scans with photopenic defects were identified,
exhibiting lower mean tumor-to-background ratio as compared
with isometabolic gliomas (P < 0.001). Gliomas with
photopenic defects had no different progression-free
survival than isometabolic gliomas in the whole population
(P = 0.40), but shorter progression-free survival in the
subgroup of World Health Organization grade II IDH-mutant
astrocytomas (35 vs 68 months; P = 0.047).},
