Abstract
Techniques of MDCT (multidetector row CT) and MRI have made great advances recently. Thin slice multiphase contrast enhanced dynamic CT can afford multi-directional reformatted images and 3D volume images which are useful for diagnosis of tumor extension. MRI includes not only MRCP (MR cholangiopancreatography) but also T1-weighted images, T2-weighted images, steady state images, and contrast enhanced dynamic images. MRI (MRCP) can offer detection of biliary carcinomas, degree of tumor extension, and secondary changes such as biliary cholestasis. Combination of MDCT and MRI can make more detailed imaging diagnosis of biliary carcinomas.
