title: Advanced postprocessing and the emerging role of computer-aided detection.
abstract: Advances in multidetector CT (MDCT) scanners have increased the pace of development of advanced postprocessing applications, such as virtual endoscopy (VE), segmentation and volumetry, and computer-aided postprocessing methods. Availability of thin-section MDCT data sets of isotropic voxel resolution ensures accuracy in structure segmentation, which is an important initial prerequisite on which the results of such advanced postprocessing applications are based. This article explains the technique of VE, segmentations and volumetry and various computer-aided post processing methods, with emphasis on their importance in the present clinical scenario.
