General CT- Scan Preparation

If your test requires oral contrast (barium), you may pick it up any day before the exam.  Otherwise, we will inform you how early you will need to arrive to begin drinking contrast. Sips of water with your regular medications are ok. Please contact us with any questions.

CT With IV Contrast

  • Nothing to eat or drink (except oral contrast, if needed) 3 hours prior to
    the exam.
  • Patients in renal failure can have the test as long as dialysis will be
    performed within 24 hours after the exam.
  • Most patients having an abdomen and/or pelvis CT must drink oral
    contrast unless specified on the prescription. Follow up oncology
    patients may be excluded from drinking oral contrast.
  • If you are pregnant or breastfeeding, or think you might be
    pregnant, please contact us prior to your exam.
