Six consecutive patients referred for CT scanning because of suspected hepatic metastases were scanned without contrast enhancement, with intravenous urographic contrast enhancement and 24 hr later with intravenous cholegraphic contrast enhancement. Unenhanced and intravenous urographic contrast enhanced scans were complementary in detecting hepatic metastases. Intravenous Cholegrafin was not effective as a contrast agent in detecting hepatic metastases.
