2.6 18F-Fluorodeoxyglucose (18F-FDG) PET Imaging
Before 18F-FDG PET imaging, the mice must be kept fasting for at least 8 hours. Each anesthetized mouse was injected with 7.4 MBq 18F-FDG (200 µL, 200 µCi) through the tail vein and kept under anesthesia until imaging (60 min, p.i.). The PET collection time was 900 s, and quantitative results were obtained by mapping the ROI on the tumor region.
