Example of parametric image of Kmet (hepatic systemic clearance of [18F]FDGal, mL blood/min/mL blood). A is before SBRT of a colorectal liver metastasis; note that the tumour does not accumulate [18F]FDGal. B is the treatment planning CT with dose color wash of 15 Gy. C and D show parametric images after 1 month and 3 months, respectively. The liver is encircled by a green line and the color scale for the PET images show Kmet ranging from 0.0 to 0.3 mL blood/min/mL liver tissue
