Abstract
A clinical trial is reported of the use of water-soluble organic iodine compounds as gastrointestinal contrast media in the examination of infants and children. These preparations are non-toxic and are presumed less likely than barium to be harmful when aspirated. They provide good visualization of the gross organ contours in routine upper gastrointestinal studies but barium sulphate appears superior in problems involving localized mucosal irregularities. A relatively high incidence of blood-stream absorption and visualised urinary excretion was noted, but no instance of systemic reaction to the medium has been observed to date.
