FIGURE 7. A 45-y-old-woman with metastatic melanoma was referred for evaluation of paraaortic lymph nodes. (A) Whole-body PET in rotating view showed focal area of 18F-FDG uptake in right upper abdomen (arrow); this uptake was confirmed on transaxial slices from CT scan (B) and PET scan (C). (D) Fused PET/CT images localized 18F-FDG–avid foci in second part of duodenum, consistent with metastatic deposit (arrows). No abnormality of paraaortic lymph nodes was observed.
