The paper presents experience in the examination of intestine and colon inflammations over the period of 12 months, demonstrating technical aspects of data acquisition, intravenous administration of contrast agent and the modes of intestine preparation. The study encompasses 70 patients (21men, 49 women). All the examinations were performed on computing tomograph with 16 parallel series of detectors by means of collimation 16 x 0.75mmafter the administration of 80 ml of nonionic contrast agent into the vein. After the intravenous administration of the contrast agent the method of two phases in one injection was used. The scanning began with the time-lapse of 30 to 35 sec since the administration of the contrast agent in order to saturate well the whole mesenterial vascular bed, both arterial and venous. The examination of 22 patients was performed by the contrast agent without preparing themorally, and most of the planned examinations (32) were performed after the administration of isodense irrigation via a duodenal probe, whereas only 16 patients were examined after oral preparation with a hyperdense contrast agent. The evaluation of 3 cases of acute enteritis, 3 cases of intestinal inflammation in immunodeficiency, 48 cases of Crohn disease, 9 cases of ulcerous colitis, 3 cases of acute diverticulitis and 4 cases of induced colitis made it possible to evaluate diagnostic importance of pathological changes in the intestinal wall. The evaluation of the type of vascularization of intestinal wall plays a significant role in the differential diagnostics of intestinal inflammations. A marked saturation of submucous or mucous layer with the contrast agent during early portal phase after the injection is the most important sign of the process activity in intestinal inflammations.
