FIGURE 2. (A) In upper abdomen, FDG PET images (coronal, transversal, and sagittal views) show focally enhanced glucose metabolism with central defect. In lower abdomen directly above bladder, coronal view shows circular lesion with enhanced glucose metabolism in outer rim and central defect. Arrowheads point to local recurrence of liver metastases. (B) Liver SPECT study (CEA-Scan; Immunomedics) reveals similar result, with tracer uptake in viable tumor mass (arrowhead). High uptake is also seen in normal liver and myocardium. (C) High uptake is seen in abdomen, similar to FDG PET. Arrowhead points to local recurrence.
