About this assessment
Tell us what feels most stressful about your child’s upcoming scan, and we’ll help you focus on the prep steps, comfort strategies, and practical details that matter most for your family.
Preparing for a child’s CT scan often means balancing practical instructions with emotional support. Parents commonly want to know what to expect during a child CT scan, whether fasting is required, how contrast works, and how to explain the scan in a calm, age-appropriate way. In many cases, children do best when they know the scan is quick, the machine takes pictures of the inside of the body, and staying still helps the pictures come out clearly. Your child’s care team may also give specific child CT scan prep instructions based on the body area being scanned and whether contrast or sedation is planned.
If your child is having contrast or sedation, you may receive special instructions about when they can eat, drink, or take regular medicines. Always follow the imaging center’s directions, since fasting before a child CT scan can vary by age and appointment type.
Bring your photo ID, insurance card, referral or imaging order if requested, a list of medications, comfort items, and anything the center asked you to complete ahead of time. For younger children, a favorite stuffed animal or blanket can help reduce CT scan anxiety in children.
Most pediatric CT scans are brief. Your child may lie on a table that moves through the scanner while staff give simple directions about staying still. If contrast is needed, the team will explain how it is given and what your child may notice.
If you’re wondering how to explain a CT scan to a child, try short, concrete phrases: 'The camera takes pictures of the inside of your body' and 'Your job is to lie still like a statue.' Avoid overwhelming details unless your child asks for them.
For children who may struggle to hold still, a short practice at home can help. Try a game where your child lies still for 10 to 20 seconds at a time while listening for a timer, then praise their effort.
Let your child know they will meet hospital staff, see a large machine, and hear instructions during the scan. Knowing what to expect during a child CT scan can make the experience feel more predictable and less scary.
Some scans use contrast to help certain body parts show up more clearly. Your child’s team may explain whether contrast is taken by mouth, given through an IV, or not needed at all. Ask about timing, possible sensations, and any extra prep steps.
Sedation is not needed for every child, but it may be considered if a child is very young, highly anxious, or unlikely to stay still long enough for clear images. If sedation is planned, the hospital will usually provide detailed eating, drinking, and arrival instructions.
It can help to ask: Does my child need to fast? Will contrast be used? Should we arrive early? Can I stay with my child? What clothing is best? Getting these answers ahead of time can make pediatric CT scan preparation feel much more manageable.
Use simple, honest language and focus on what your child can do: lie still, listen to directions, and bring a comfort item if allowed. Avoid giving too much information at once. Many children feel calmer when they know the scan is usually quick and that a parent may be nearby depending on the facility’s rules.
Sometimes. Fasting before a child CT scan may be required if contrast or sedation is planned, but not every scan has the same rules. Follow the exact instructions from your child’s imaging center or hospital, since timing can differ by age and procedure.
Bring identification, insurance information, any required paperwork, a medication list, and comfort items for your child. You may also want a change of clothes, snacks for after the appointment if fasting was required, and any forms the hospital asked you to complete in advance.
Keep it brief and concrete. You might say, 'The machine takes special pictures of the inside of your body,' and 'You’ll lie still on a table while the staff helps you.' Tailor your explanation to your child’s age and let them ask questions.
Not always. Many children can complete a CT scan without sedation, especially if they can stay still for a short time. Sedation for child CT scan prep is more likely when a child is very young, very anxious, or unable to remain still long enough for clear images.
