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.
