Comment: 750cc of oral contrast is given in divided doses beginning approximately one hour prior to the study. Delayed scans may be useful in select cases. In cases of suspected pelvic abscess rectal contrast may prove useful to define the position of the rectum and sigmoid colon. We use a 3% Hypaque solution. |
