View larger version (76K): [in a new window]   Fig. 1A. —68-year-old man with head and neck tumor of unknown primary origin detected after neck dissection on right side. Positron emission tomography (PET)—CT was performed without oral contrast media. Coronal PET image shows high-intensity FDG uptake in ascending colon.

Positron emission tomography (PET)—CT was performed without oral contrast media. Fused coronal PET-CT image at same location as A shows no opacification of intestinal structures in CT image.

Fused coronal PET—CT image at same location as A shows opacification of intestinal structures in ascending colon while high-intensity FDG uptake is present in ascending colon.
