Scintigraphic study of regenerative nodules due to fulminant hepatic failure.

We report the case of a 25-year-old woman with fulminant hepatic failure (FHF). Liver scintigraphy using (99m)Tc-galactosyl human serum albumin (GSA) and (99m)Tc-phytate produced interesting findings; regenerative nodules appeared as nodules of increased accumulation of (99m)Tc-GSA, whereas these nodules were expressed as defects of accumulation of (99m)Tc-phytate. These scintigraphic findings suggested that the functions of hepatocytes in regenerative nodules were maintained, whereas those of Kupffer cells were impaired.
