CT gastrography.
Kim JH, Park SH, Hong HS, Auh YH.
The rapid dissemination of multidetector-row computed tomographic (CT) technology will make faster and more accurate gastric imagining available. Two-dimensional multiplanar reconstruction and CT gastrography including virtual gastroscopy and transparency rendering using volume rendering are types of interactive two- and three-dimensional medical imaging tools. It provides multiplanar cross-sectional imaging, gastroscopic viewing, and upper gastrointestinal series imaging in the same data acquisition. Two-dimensional multiplanar reconstruction provides accurate staging of gastric cancer and extraluminal information such as lymphadenopathy and distant metastasis. Virtual gastroscopy detects subtle mucosal changes and differentiates them from submucosal lesions in the same way as gastroscopy. Transparency rendering provides global orientation of the focal findings in the stomach in the same way as upper gastrointestinal series findings and provides useful information for preoperative mapping. Thus, CT gastrography is a promising method for evaluating gastric lesion despite its limitations.
