Figure 1.
Whole-body BLI and small-animal PET images of the head [coronal (i); sagittal (ii)] showing tumor (white arrows) visibility at 4 weeks post-tumor cell implantation. Both mice shown have similar luminescence of 4 × 107 p/s/cm2/sr. The FLT signal is greater than that of brain background, whereas the FDG signal is not.
