FIGURE 5. Focus 120 microPET images of animals bearing LS174T human colorectal cancer xenografts 1.7 h after 18F-FDG. All images were taken at same maximum intensity and background set to 0.0. (A) Photographs of 3 tumor-bearing animals. (B) Coronal slice (0.82-mm thick) taken to highlight uptake in tumor (arrows), as well as in bone marrow (BM) of shoulder and in hind quarters. Heart (H) and brain can also be seen in some images. Bars represent planes used for transverse and sagittal sections. (C) Transverse sections that highlight tumor or heart wall uptake. Sagittal sections illustrate the side view of tumor (D) and a plane that highlights heart, bone marrow, and urinary bladder (UB) activity (E). Tumor weights were 0.425, 0.321, and 0.153 g, respectively.
