Some people may be concerned about the amount of radiation they receive during a CT scan. It is true that the radiation EXPOSURE from a CT scan can be higher than from a regular x-ray. However, not having the procedure can be more risky than having it, especially if cancer is suspected.

People considering CT must weigh the risks and benefits. In very rare cases, CONTRAST agents can cause allergic reactions. Some people experience mild itching or hives (small bumps on the skin). SYMPTOMS of a more serious allergic reaction include shortness of breath and SWELLING of the throat or other parts of the body. People should tell the technologist immediately if they experience any of these symptoms, so they can be treated promptly.
