title: [Morphological and functional evaluation criteria of hepatobiliary functional scintigraphy with 99mTc-diethyl-IDA in hepatocellular jaundice].
abstract: In 31 patients with histologically proven hepatocellular jaundice hepatobiliary scintigraphy with Tc-99m labelled IDA derivatives was performed. Results were classified under morphological (demonstration of liver parenchyma, ductus choledochus, bile ducts, gallbladder, kidney) and functional (Tmax, half time of bile excretion, appearance of activity in ductus choledochus, gallbladder, and intestines) criteria. The liver parenchyma could be demonstrated in 90.3% of cases, ductus choledochus in 71%, and the gallbladder in 72.4%. The type of tracer excretion into the intestines showed 9.5% activity accumulation in the gallbladder with late bile excretion into the intestines and 90.5% early activity excretion into the duodenum with late filling of the gallbladder. The intrahepatic bile ducts were demonstrated in 22.6% (left hepatic duct) and 6.5% (right hepatic duct). In 35.5% of cases the kidneys were still visible after 15 min p.i. All cases showed - sometimes delayed - bile excretion into the GI tract. The time of appearance of activity in ductus choledochus (18.4 min) and gallbladder (39.5 min) was delayed. The liver histogram showed likewise delayed values concerning Tmax (14.3 min) and half life of tracer excretion (greater than 30 min) when compared to controls. The differentiation of hepatocellular jaundice from obstructive jaundice is possible by the demonstration of bile excretion into the intestines, normal width of the bile ducts, and filling of the gallbladder.
