    Abstract:
    The relative merits of three radiopharmaceuticals for evaluating liver transplant patients were determined in paired studies. In 86% of studies both 131I-RB and 99mTc-PG gave similar information for differentiation of hepatocellular disease and billary tract obstruction. 99mTc-PG probably demonstrates the biliary tract and small intestine better early after injection (8%); 131I-RB is probably better in showing the colon at 24 hours when intestinal activity is not seen by 1 hour (6%). 99mTc-diethyl-IDA is superior in all respects when compared to 99mTc-PG. The blood retention method (20 min./5 min.) showed that none of the radiopharmaceuticals was a reliable indicator of hepatocyte function when compared to total serum bilirubin.
