Abstract

The increased temporal and spatial resolution of most modern MDCT scanners enables routine examination of the gastrointestinal tract in small animals. In patients with neoplastic and nonneoplastic obstructive diseases, MDCT can be used to identify the affected segment and, in most cases, the cause of obstruction. In neoplastic conditions, MDCT is essential for staging and aids intervention planning. In fact, the main advantage of MDCT over other imaging techniques and endoscopy is that it enables tumor detection and staging during the same procedure. Advanced MDCT scanners can acquire datasets with the high resolution needed for diagnostic multiplanar reconstruction and 3D virtual endoscopy.
