Fig. 5From: Carbon ion radiotherapy: impact of tumor differentiation on local control in experimental prostate carcinomas[18F]FAZA-PET/CT of a HI-tumor 2 h post tracer injection, before (a) and after single fraction of 12C-ions (b) in axial (left panel) and coronar (right panel) image orientations. The PET tracer is color-coded and overlayed to an aligned CT image. Before RT (a), a high tracer uptake was found in the tumor as well as in the bladder due to partly urinary excretion of the tracer. 7 days after RT (b), the same tumor showed a tracer uptake in the bladder but not in the tumorBack to article page
