| [ Summary ] | We evaluated the usefulness of three-dimensional (3D) spiral CT images, using a volume rendering technique for the diagnosis of gastric submucosal tumors. 3D CT images provide useful information not only the location and extension of the tumor, but also the relationship between the tumor, surrounding organs and vascular systems. Virtual endoscopy enables us to obtain images similar to those obtained with conventional endoscopy. Furthermore, by changing the degree of transparency, extraluminal information can be obtained with 3D CT data sets. Texture mapping techniques, which synthesize 3D and multiplanar reconstruction, take advantage of the accurate internal texture, origin, and vascularity of tumors. 3D CT images are useful for follow up studies and planning surgical procedures. | |
