How to Prepare for Your CT Scan

Even though you may be asked to change into a gown once you show up for your procedure, consider wearing comfortable and loose-fit clothing. You will be given instructions on removing the following objects, as these may affect CT images:

  • Metal objects, including jewelry, eyeglasses, dentures, and hairpins
  • Hearing aids and removable dental work
  • Bras containing metal underwire
  • Remove any piercings, if possible

If contrast material is used during your procedure, you will be asked not to eat or drink anything for a few hours beforehand.

You will want to inform the technologist and facility performing the CT procedure the following information: 

  • If you are on any medication
  • If you have any allergies to food coloring or dyes, as contrast material may contain such ingredients. 
  • Note: Contact your referring doctor if you are allergic to IV contrast used for CT procedures, he may prescribe medications to reduce the risk of allergic reactions, which will need to be taken ahead of time, usually about 12 hours before contrast material. Contact your doctor well before the exact time of your CT scan to avoid any unnecessary delays or rescheduling your appointment.
  • Of any recent illnesses or medical conditions
  • Of any history of heart disease, asthma, diabetes, kidney disease or thyroid problems (these conditions may increase the risk of an unusual adverse effect).
  • Women should always inform their physician and the CT technologist if there is any possibility that they may be pregnant.

After this, try to relax during your CT scan, the technologist are professional and will address any questions that you may have prior to the CT scan.  Thinking positive thoughts, can help pass the time quickly.
