title: Technetium Tc 99m DTPA galactosyl human serum albumin to measure changes in hepatic functional reserve after transcatheter arterial embolization of the liver.
abstract: OBJECTIVE
  To describe the acute and subacute changes in hepatic functional reserve using technetium Tc 99m diethylenetriaminepentaacetic acid galactosyl human serum albumin (Tc-99m DTPA GSA) in patients with hepatocellular carcinoma and liver cirrhosis who had undergone transcatheter arterial embolization (TAE).
  
  
  METHODS
  Sequential Tc-99m DTPA GSA hepatic scintigraphies were performed prospectively in 26 consecutive patients with hepatocellular carcinoma and liver cirrhosis approximately 1 week before, 2 days after and 1 month after TAE. Counts per 10 seconds of the heart region of interest on 3- and 15-min images and the liver region of interest on a 15-min image were calculated.
  
  
  RESULTS
  Clearance index decreased (p < 0.001) and receptor index and modified receptor index increased 2 days after TAE (p < 0.001 and p = 0.004, respectively), but these changes did not persist 1 month later.
  
  
  CONCLUSIONS
  This study has established an expected pattern of behaviour of the liver after TAE, which could be used to monitor progress of patients who undergo the procedure.
