FIGURE 1. Results for patient 2, a 52-y-old woman with a B-cell diffuse large lymphoma. (A) A baseline ¹⁸F-FDG PET image revealed increased activity in left subclavicular and paraaortic abdominal nodes. (B) At day 1, almost all abnormal uptake was sharply reduced. (C) At day 20, although bowel uptake was seen, abnormal uptake in lymph nodes was negligible. (D) At the end of chemotherapy, abnormal uptake to lymph nodes was not apparent.
