  • Could I have a reaction to the IV contrast?

Yes, but the chances are minimal. It has the same risk for reaction as any medication does, which is why we use contrast screening forms to check for possible patients who are at risk of having reaction to the contrast. Although rare, the contrast medium involved in CT scan poses a slight risk of allergic reaction. Most reactions are mild and results in hives itching and rashes. In some rare instances, an allergic reaction can be serious and potentially life-threatening, including swelling in your throat ,mouth or shortness of breath.  If you experience this, tell your technologist immediately.
