Abstract
We attempted to make 3 dimensional images (3-D images) of intrahepatic bile ducts which were reconstructed from cholangio-CT using a 3-dimensional imaging pogram. In this report,8 cases of 3-D images of bile ducts were studied. In the 3-D image, closer bile ducts appear white and as the distance increases, bile ducts appear gradually grey to black. This is useful for comprehension of bile duct division, and all subsegmental bile duct branches were clearly detected because 3-D images could be made from randomized angles. The image which obained the subsegmental division and the full length of branch was defined as excellent, and the excellent angle for every subsegmental branch was determined. To demonstrate intrahepatic bile ducts,8 angles from 0°to 330°were ncccssary in 3-D images of CT cholangiography.
