Are CT Scans Safe?

MRI Scan

A computed tomography (CT) scan or CAT scan is just one of the sophisticated tests you’ll find at Concord Imaging in San Antonio. If you have safety concerns about radiology exams, please feel free to discuss these with your doctor or the radiology professional. During your CT scan, you’ll be exposed to low levels of radiation, as the CT scanner uses X-ray technology to create medical images. There is a risk of cancer caused by radiation and CT scans expose patients to higher levels of radiation compared to the typical dose of a chest X-ray. However, medical experts tend to agree that the risk of cancer caused by radiation is generally smaller than a person’s natural risk of cancer.

Some patients undergoing CT scans are asked to receive a contrast agent prior to the exam. The contrast agent helps to improve the clarity of the medical images. Rarely, some people may experience allergic reactions from this substance. Your doctor might recommend a different medical imaging test if you are pregnant or breastfeeding, due to the risk of radiation to the child.
