Examples of CT examinations from our study performed in three different patients demonstrate the benefits of oral contrast administration. In the first patient (a,b), a duodenal perforation was confirmed by the extravasation of oral contrast (arrow). Two other patients (c,d and e,f) underwent CT examinations that were performed within a short time period of one another, one without oral contrast and the other with oral contrast. In each case, a diagnosis of tumor fistula with bowel was directly identified only on the examinations with oral contrast (arrows).
