Abstract
In report 1 the authors compared to discriminate between congenital atresia of the bile ducts and infantile hepatitis according to a liver scintigram and a linear scan with 131I-BSP. In this report, the authors would like to report on the characteristics of cholangiectasis. As in report 1, a liver scintigram and a linear scan were prepared immediately, 3 hours, and 24 hours after the intravenous injection of 131I-BSP.
There were many cases in which the liver scintigram revealed the compressed pictures near the portal fissure region and the concentrations of isotope right downward. These pictures and concentrations appeared obviously gradually with the lapse of time. In the linear scanning study, the peak of the scanning pattern in congenital cholangiectasis did not appear so rapidly as that in congenital atresia of the bile ducts.
The linear scanning pattern had two peaks in the bile duct region, the first peak produced by the isotope concentrated in the liver, the second peak produced by the isotope concentrated in the enlarged part of bile duct. This disease is characterized by the above pattern.
