From: Comprehensive analysis of the influence of G-CSF on the biodistribution of 18F-FDG in lymphoma patients: insights for PET/CT scheduling

Fig. 2

Fifty-two-year-old male patients imaged at baseline (a, b) and after 4 cycles of R-ACVBP (c, d). Interim PET/CT was performed 7 days and 6 days following the last injection of chemotherapy and G-CSF, respectively. The injected G-CSF was lenograstim, at a dosage of 34MUI daily for a 4-day period. In this case, low hepatic 18F-FDG uptake can be observed at baseline because of a tracer sequestration in the bulky mass. This pattern resolves after the tumour had shrunk on interim PET/CT, but because of a short time-lapse between the last chemotherapy injection and interim PET/CT, an increased bone marrow and splenic uptakes are observed
