[Common bile ductal carcinoma, hilar cholangiocarcinoma: evaluation with MR cholangiography].

Recently, imaging of bile ductal carcinoma has been improved by new techniques such as MR cholangiography. Cancer invasion along the bile duct has been demonstrated by MR cholangiography. MR cholangiography will be useful for obtaining more detailed information in the diagnosis and staging of common bile ductal carcinoma, hilar cholangiocarcinoma.
