What is a CT scan?

CT (Computerized Tomography) is an imaging test that uses X-rays to create detailed images of the body. During the test, patients lie on a table as it moves through a large, circular scanning device. Most CT scans take between 15-30 minutes.

Images from a CT give the radiologist and your doctor detailed information about your body to help care for you. To keep patients safe, the radiation level is set as low as possible on all of our CT machines.

Patient Instructions for a CT

Here are some general guidelines for patients undergoing a CT scan:

  • Some exams require you to be NPO (nothing my mouth) for 4 hours prior to the CT. Check with your physician if you are uncertain. Take your regular medications unless directed otherwise by your physician.
  • Wear comfortable clothing for the exam. Patients may be asked to remove any metal objects or body piercings.
  • IV contrast is used for many exams. Contrast goes directly into a vein through an IV to enhance anatomy. This contrast can make you feel flush, as if you are wetting your pants, give you a metallic taste in your mouth or nausea. This should only last about 30 seconds and are normal feelings. If you have difficulty breathing or feel itchy, you need to let the technologist know right away. If you know you have an allergy to Iodine, contact your physician so he/she can prescribe a medication for you to take prior to the CT.
  • Some scans involving the abdomen or pelvic area require oral contrast, which helps to highlight the bowel. It typically takes 1 ½ hours for the oral contrast to go through the body before the CT scan can be performed.
  • During the exam, patients should lay as flat and still as they can.
  • If you have been given IV or Oral Contrast drink extra water to flush the contrast out of your system after the CT.
