2. Figure 1
(A) Axial and coronal ceCT, fused PET/CT, and PET images through the thorax of a 60-year-old woman with metastatic esophageal cancer. CT and fused PET/CT images show a FDG-avid thickened esophagus (straight white arrow), right pretracheal lymphadenopathy (curved white arrow), and left supraclavicular lymphadenopathy (curved black arrow). (B) Diffuse uptake in the mediastinum secondary to esophageal (straight white arrow), periesophageal (arrowheads), mediastinal adenopathy (arrowheads), and abdominal lymphadenopathy (curved white arrow). Supraclavicular lymphadenopathy also is seen (straight black arrow). There is normal physiologic FDG uptake in the brain, kidneys, and bladder.

3. Figure 2
(A) Axial and coronal ceCT, fused PET/CT, and PET images through the liver and upper abdomen of a 48-year-old man with metastatic colorectal cancer. Images show multiple hypodense FDG-avid liver metastases distributed throughout the right lobe of the liver (straight white arrow, segment 5 lesions; curved white arrow, segment 7/8). (B) Axial and coronal ceCT, fused PET/CT, and PET images of the same 48-year-old patient. Further images through the spine show a minimally expanded sclerotic lesion in the left pedicle (straight white arrow) of T 10, which is FDG avid on the PET and fused PET/CT images (curved white arrows), which precludes surgical management for the liver masses. FDG-avid hepatic lesions also are seen in the upper right lobe of the liver (straight black arrow).

4. Figure 3
Axial and coronal ceCT, fused PET/CT, and PET images through the thorax of a 62-year-old woman with metastatic pancreatic cancer. Images show a distal FDG-avid pancreatic mass (curved white arrow) with a segment 5, low-attenuation, FDG-avid mass consistent with a liver metastasis.
