However, in the case of severe calcifications and stents, significant stenosis may easily be overseen when using VRT and MIP. Therefore, MPR and curved planar reformation maybe an alternative for displaying diseased vessel segments. To improve the rapid availability of these post-processing alternatives, automated segmentation and vessel centerlining would be required, which is still a topic for further debate.

Various post-processing techniques have been shown to be effective in displaying the biliary tract. Multiplanar reformatted images in the coronal, oblique coronal or oblique axial plane help to define the location and extent of the disease shown on native images (Fig. 22.4). However, since most structures of interest do not lie within a single plane, this technique is limited to the visualization of the entire biliary tract, and particularly of the entire common bile duct, unless curved planar reformation is used (Nino-Murcia et al. 2001).

However, since most structures of interest do not lie within a single plane, this technique is limited to the visualization of the entire urinary tract and particularly the entire ureter unless curved planar reformation is used.
