FIGURE 3. Results for patient 12, a 76-y-old man with a B-cell diffuse mixed lymphoma. (A) A baseline 18F-FDG PET image revealed multiple foci of increased activity in mesenteric lymph nodes. (B) At day 1, uptake in mesenteric lymph nodes was visually identical to that at baseline. (C) At day 20, abnormal uptake disappeared. Renal uptake was unclear because of the presence of multiple renal cysts. (D) At the end of chemotherapy, the 18F-FDG image showed no abnormal uptake.
