[CT-Sellink--a new method of evaluating the intestinal wall].

34 patients were examined by CT following a modified enema (CT-Sellink) in order to demonstrate the gut. By introducing a "gut index" it is possible to define the tone of the gut providing its folds remain constant. By means of a radial density profile the gut wall can be defined objectively and in numerical terms. Gut wall thickness in the small bowel averaged 1.2 mm with a density of 51 Hu and gut wall thickness in the colon averaged 2 mm with a density of 59 Hu.
