Computed tomography (CT) gastrography is a noninvasive gastric imaging technique that uses two-dimensional (2-D) CT scans to obtain pictures of the stomach and surrounding anatomy. Specialized workstations and software can then convert the CT images to three-dimensional (3-D) images by using volumetric reconstruction.1,2 Using a multislice computed tomography (MSCT) scanner for the procedure can provide thinner slices and faster scanning, resulting in improved image quality.3 The 3-D images created by the specialized software and workstations can potentially depict gastric mucosal patterns more clearly than 2-D images alone.4 Patients with CT gastrography findings that suggest cancer require a...
