Hepatocellular adenomas appear as cold nodules on technetium-99m (99m Tc) sulfur colloid scans, which distinguishes them from FNH, which typically shows normal or increased colloid uptake. This is due to the altered blood flow through the lesions and the lack of phagocytic activity of Kupffer cells.
