Biliary tract: three-dimensional helical CT without cholangiographic contrast material.
Zeman RK., Berman PM., Silverman PM., Cooper C., Garra BS., Patt RH., Ascher SM.
Bile duct anatomy depicted with a three-dimensional (3D) model developed with helical computed tomography (CT) data was compared with cholangiographic depiction. The ductal system was completely displayed from all angles in four of six patients, as well as the stricture and length of bile duct between strictures and the bifurcation in five of six cases. 3D rendering can depict preoperative ductal anatomy.
