Abstract
Iohexol (Omnipaque) was used for enhancement of brain CT [computed tomography] in 17 patients with previous adverse reactions to contrast media. Two of these patients also had cerebral angiography using iohexol. No premedication was given. The only adverse reaction was a skin reaction 24 h after the iohexol injection, which might have been induced by the contrast medium or antibiotic treatment. Five of the patients had repeated iohexol injections at different occasions without adverse reactions.
