Overview of Computerized Tomography (CT) Scans

Risks Of A CT Scan

A computerized tomography scan is generally known to be a safe procedure for most individuals. While ionizing radiation is used during one of these scans, the exposure to the patient is minimal. Thus, it should not have any long term effects. Even though the dose of radiation is low, it can harm an unborn baby, so a pregnant woman or one who thinks they may be pregnant should not have one.

Additionally, a patient can have an allergic reaction to the contrast agent used for their computerized tomography scan. Individuals who have a known allergy or sensitivity to iodine, contrast dye, or shellfish should speak to their doctor before having a computerized tomography scan with contrast.

The reason is that the contrast medium can induce acute kidney failure.
