Improved uniformity of aortic enhancement with customized contrast medium injection protocols at CT angiography. 4 Fleischmann D, Rubin GD, Bankier AA, Hittmair K.Computed tomography of the stomach with water as an oral contrast agent: technique and preliminary results. Multidetector CT is a valuable tool for the evaluation of gastric wall disease and serves as an adjunct to endoscopy. Gastric inflammation (gastritis, ulcers, Ménétrier disease) and miscellaneous gastric conditions (emphysema, gastric outlet obstruction, varices) can also be visualized with multidetector CT. In addition, multidetector CT allows detection of other gastric malignancies (lymphoma, carcinoid tumors, metastases, gastrointestinal stromal tumors) and benign gastric tumors (neural tumors, polyps). Preoperative staging of gastric carcinoma appears to be the main clinical indication for multidetector CT. In contrast to gastroscopy and double-contrast studies of the stomach, CT provides information about both the gastric wall and the extragastric extent of disease. Proper distention of the stomach and optimally timed administration of intravenous contrast material are required to detect and characterize disease.

When thin collimation is used, near-isotropic imaging of the stomach is possible, allowing high-quality multiplanar reformation and three-dimensional reconstruction of gastric images. Multidetector computed tomography (CT) offers new opportunities in imaging of the gastrointestinal tract.
