Abstract
The authors carried out a scintigraphy and a linear scan in 23 patients with congenital atresia of the bile ducts using 131I-BSP, and compared to discriminate from those in infantile hepatitis. The liver scintigrams and the linear scans were taken immediately, 3 hours, and 24 hours after the intravenous injection of 131I-BSP.
In congenital atresia of the bile ducts, the scintigram revealed no picture of 131I-BSP excreted in the intestinal tract even after 24 hours, but many pictures excreted in the kidney in general. In linear scanning study, the scanning curves were similar in every test time, there being many backgrounds. In infantile hepatitis, on the other hand, the scintigram showed the increasing excretion in the intestinal tract with time and the reducing background. Also in the linear scan, the curves showing the excretion in the intestinal tract were obtained.
