TSPO and glioma: Figure 5 shows the TSPO PET scan of a glioma patient 14 days after stereotactic biopsy. A total of 170 MBq [18F]GE-180 were injected intravenously and emission data were acquired 60–80 min p.i. The PET images show a focally increased TSPO radioligand uptake in the left parasagittal area (white arrow) and a glioma recurrence was confirmed in neuropathological analyses.
