Abstract
Sophia Health Improvement Center introduced the hospital information system with perfect film-less and paper-less in 2001. Successful results indicate benefits in the examination process of health checking system. Further, gastric virtual endoscopy (VE) was developed. MD-Row-CT (16ch) images of the abdomen with 1mm thickness were first obtained and reconstructed to VE images by surface and volume rendering. Results indicated VE images were able to show subtle alteration of mucosal folds. Gastric cancer, polyp, ulcer, erosion and gastritis were clearly visualized. By comparison studies between VE and gastric fiberscopy (GF), sensitivity 92.7%, specificity 90.9% were calculated. As 3D MD-CT examination of the stomach is noninvasive except radiation exposure, it will be expected to become a new technique of the stomach examinations.
