From: Dynamic FDG PET/CT for differentiating focal pelvic uptake in patients with gynecological cancer

Summed image and four serial whole-body dynamic PET images (1st − 4th, 3 min each) of a patient with endometrial cancer (arrows). One focal uptake is observed in the left abdomen in the summed image, and the uptake disappears in 4th phase (arrowheads). This one was clinically diagnosed as physiological uptake in the colon.
