A 74-year-old man with history of prostate cancer underwent 18F-choline PET/CT for restaging. Early acquisition of the pelvic region revealed intense uptake in prostate, with infiltration of the posterior wall of the bladder. Furthermore, focal uptake in the thickened anterior wall of the rectum was detected. Whole-body scan at 60 minutes confirmed early findings in pelvis, although the infiltration of the bladder was no more evident due to interference of radioactive urine. Biopsy demonstrated the presence of colorectal carcinoma. The dual-phase protocol resulted in significant clinical impact to clearly characterize focuses of abnormal 18F-choline uptake in the pelvic region.
