FIGURE 4. Coronal T1-weighted MR image (A) demonstrates right parailiac lymphadenopathy (arrow) in patient with uterine cervical cancer. 18F-FDG PET image (B) clearly shows intense uptake in right parailiac region (arrow), indicating lymph node metastasis. Although 11C-choline PET image (C) detects abnormal activity (arrow), physiologic bowel uptake (arrowheads) mimics parailiac lymph node metastases. Lymphadenopathy was not seen on follow-up MR images after transarterial infusion of chemotherapy. BL = bladder activity.
