Figure 5.
PET/CT images at 24, 48, and 72 h postinjection of a HER2-negative tumor-bearing mouse (SUVmean scale 0.3–2). No PET signal could be visualized in the tumor at the selected window to compare with the HER2-positive mice. The tumor is located on the left shoulder in the same area as the HER2-positive tumor-bearing mice.
