  • Abstract
  • Look Inside

 Virtual endoscopy is a new method of gastrointestinal imaging in which thin-section, helical-computed tomography is used to generate high-resolution, twodimensional axial images. Three-dimensional images of the gastrointestine, simulating those obtained with conventional endoscopy, are then reconstructed off-line. Since virtual endoscopy is minimally invasive compared to conventional endoscopy, its use for colon screening has been postulated. On the other hand, virtual endoscopy may play only a minimal role for gastric cancer screening because of the well-established double-contrast gastric series method and the safe and relatively tolerable conventional endoscopy. Alternatively, CT can play a more important role in the staging of gastric neoplasms.
