Enhanced CT of the abdomen is effective in examining the abdominal organs, including the duodenum, jejunum, ileum, and other small bowel structures. The scope of the abdominal examination usually includes the entire abdominal cavity, including the abdominal intestinal structures, as well as the liver, gallbladder, pancreas, and spleen. In addition, the contrast medium used in enhanced CT is more responsive to the blood supply of certain lesions than plain CT. For abdominal cavity organs such as the small intestine, enhanced CT can show tumor tissue or polyp lesions in the wall of the jejunum and duodenum, abnormal peri-intestinal space-occupying lesions, structural abnormalities of the mesentery, and intestinal obstruction or narrowing. Avoid eating as much as possible before the abdominal CT examination to avoid the influence of food and other factors on the results of the image display. For suspected small bowel lesions, it is recommended to go to the hospital promptly.
