Computed tomography, also known as CT or a CAT scan, is a diagnostic test that utilizes x-ray beams to produce images of inside the body. Unlike traditional x-rays, CT images provide information of soft tissues inside the body and when combined with intravenous contrast also allow non-invasive evaluation of blood vessels. CT scans are fast, painless, non-invasive, and accurate.
Tell your doctor if there’s a possibility you are pregnant and report any iodine or contrast allergies. You will be instructed not to eat or drink anything for a few hours beforehand. If you have a known allergy to contrast material, your doctor may prescribe medications to reduce the risk of an allergic reaction. These medications must be taken 12 hours prior to your exam. Leave jewelry at home and wear loose, comfortable clothing.
