Fig. 2.

PET/CT and SPECT/CT images of C57Bl/KaLwRij mice inoculated with [⁸⁹Zr]oxinate₄- or [¹¹¹In]oxinate₃-labelled eGFP-5T33 cells. Scans of ¹¹¹In (top) and ⁸⁹Zr (bottom) are reported from 30 min to 7 days after i.v. inoculation of C57Bl/KaLwRij mice with 10⁷ eGFP-5T33 cells labelled with 5 MBq [⁸⁹Zr]oxinate₄ or 10 MBq [¹¹¹In]oxinate₃. Image scales were adjusted to the maximum activity concentration within each image except for the 2-h images where the activity scale was adjusted to the maximum activity per voxel used in the 30-min image in order to quantitatively visualise the rapid change in the early homing pattern of eGFP-5T33 cells after i.v. inoculation
