Evaluation of lesions within or close to the bladder will be hampered by the intense accumulation of urinary FDG activity. Irrigation of the bladder with sterile saline is an option that may be used to decrease the activity in the bladder when there are specific concerns of pelvic or lower abdominal tumors.

Depicted above is a patient with metastatic colon carcinoma. Note the proximity of the primary lesion to the bladder. In addition to detecting the primary colon carcinoma, the FDG-PET technique also allows for the preoperative detection of liver metastases. In the above example, liver metastases are readily apparent. Metastases from colon carcinomas often are found in the liver due to the direct drainage of venous blood from the colon into the liver.
