Comparison of pre- and post-irradiation dtp FET PET and MRI images of glioblastoma long-term survival in the right frontal lobe. Dtp FET PET volume < 40 cm3. The large pathological uptake volume extends into the SVZ over a substantial area (a). Contrast-enhanced T1-weighted MRI performed for radiotherapy planning with no SVZ infiltration in the axial, sagittal, and coronal planes (b). The patient had a favorable outcome, being alive at the end of the observation period (OS 47 months) without progression. Twelve months post-treatment dtp FET PET with complete response: TBR below 1.6 (c) and MRI with residual contrast enhancement (d)
