What are the odds of the contrast affecting me?
The vast majority of people have no adverse reaction to the contrast agent used during CT scans. You are most likely one of them. When dye is injected, you may feel a fleeting sensation of warmth and get a metallic taste in your mouth, but these are harmless symptoms. In very rare cases people develop an allergic reaction to the contrast which can consist of nausea, vomiting, and/or shortness of breath. These symptoms should be reported to the technologist monitoring the examination.
