The use of radionuclides in the investigation of conjoined twins.
Three sets of thoraco-omphalopagous conjoined twins were investigated. The clinical findings indicated a complex shared heart in two sets, and separate cardiovascular systems in the other. These assessments were confirmed by dynamic imaging after bolus injection of Tc-99m(Sn)colloid or Tc-99m millimicrospheres. Static images were then used to establish the configurations of the shared livers. The results of these studies were in keeping with the angiographic and autopsy findings in the two sets with complex cardiac anomalies and with the surgical findings during successful separation of the third set.
