Is CT scanning a safe procedure?
CT scanning uses X-rays, and the amount of radiation exposure is similar to that of many ordinary X-ray examinations. The risk from this amount of radiation is minimal for most people, but can be more for a fetus. CT scanning is therefore not usually performed on pregnant women, unless absolutely necessary. Intravenous contrast material can cause allergic reactions in some people. These reactions are usually minor (such as a temporary skin rash or hives) and require little or no treatment; more serious reactions are very rare.
