Evaluation of biliary malignancies using multidetector-row computed tomography

Abstract

The development of multidetector-row computed tomography has provided a number of advantages for the evaluation of biliary malignancies. Because of its fast-scanning ability, multiphasic scans can be performed with improved temporal resolution. Volumetric data acquired by thin collimation enable the application of various image-processing techniques for displaying variable volume thicknesses in 1 plane. Volume-rendering or computed tomography cholangiography techniques are also useful for demonstrating the 3-dimensional relationships of anatomical structures and pathological lesions.
