The number of people who are being subjected to a CT or MRI scan is increasing every day. Many of the scans involve the injection of a contrast medium. Although reactions to the contrast material are rare there is a small risk that they can cause allergic reactions or other medical problems. Most reactions if they occur are mild. In rare instances the reaction can be serious. Every doctor who requests a scan should be aware of the risks and should inform the patients accordingly. This paper covers basic details about possible reactions.
