The Role of Multidetector Computed Tomography in evaluation of gastric cancer

Abstract

All the 3D imaging methods could show the lesions of gastrointestinal tracts, each with its own characteristics. MPR image could show the lesion in any section, e.g. sagittal oblique though it could not get 3D perception. It could remedy the defects of transverse images, with the advantages of showing the lesions with wall invasion. Image of VE and SSD with cutting techniques can show the size and shape of lesions, especially intraluminal prominent lesions, and show the structure of gastrointestinal tracts. They can better show the base and pedicel of lesions, but cannot discern surface coloration of lesion and extraluminal tumor invading. Volume-rendered image reconstruction images VR can be made translucent, similar to those of double contrast barium studies, and can demonstrate the overall contour changes of gastrointestinal tracts, but with poor mucosal information (Shao-Yin et al., 2006).
