Ct Scans are monitored and regulated to provide the minimum amount of radiation and the 64 slice CT scan generates less radiation then the current CT scans. The exposure is minimal but is needed to produce the images. The risk associated with any individual scan is small; however, the risk increases as numerous additional studies are performed. Because of radiation exposure, a CT scan is not usually recommended during pregnancy.
There are some patients who are allergic to iodine solution; these patients have a wide variety of responses to the iodine solution. Most allergic reactions are limited to hives (itchy bumps on the skin). Extremely infrequently a person will have a serious reaction to the iodine (1 per 40,000 people who have this test). As with the use of any medication, the chance of a fatal reaction does exist. However, most allergic reactions are transient and require no treatment.
If you are allergic to the iodine contrast material (dye) you should be pre-medicated 24 hours prior to your exam. This is a must in any patient with a prior history of anaphylactoid contrast reaction and strongly advised in patients with prior history of “minor” contrast reactions. If this pertains to you, notify your doctor. |
