Imaging/Radiology FAQs

Frequently Asked Questions - CT scans:

  • Should I have a CT scan if I’m pregnant?
    Be sure your healthcare provider knows you are pregnant. Together you and your healthcare provider can decide whether you should have a scan.
  • Do I have to check into the hospital?
    You usually don’t have to be admitted for a CT scan.
  • Do CT scans hurt?
    No. However, some people may feel anxious when entering the scanner or may experience some discomfort after being given the contrast medium.
  • What is a contrast medium?
    Contrast medium is a substance that often is given by mouth or injection at some point in the CT scan procedure. It highlights certain areas, making the results more readable. Some people may experience an allergic reaction. Inform your healthcare provider if you have any allergies, particularly to iodine. Some may experience flushing, nausea, headache or a salty taste in the mouth. An itching sensation or shortness of breath may indicate an allergic reaction to the medium. You may be asked to avoid food or fluids four to eight hours before the test.

  • How long does a scan take?
    The total amount of scanning time ranges from 20 to 45 minutes.
  • Can people with metal implants be scanned?
