CT images of internal organs, bones, soft tissue and blood vessels provide greater detail than traditional x-rays, particularly of soft tissues and blood vessels. CT scans may be performed on newborns, infants and older children.
Is CT scan safe for infants?
CT scans have risks.
CT scans use radiation, which can increase the risk of cancer. Children, and especially infants, have greater risks because their brains are still developing. And unnecessary CT scans can lead to more tests and treatments, with more risks.
Does a baby have to be sedated for a CT scan?
Placing the IV will feel like a quick pinprick, and the solution is painless as it goes into the vein. Sedation may occasionally be required if your child can’t lie still for the scan. Sedation medicines are given through an IV line and help to keep a child comfortable during the CAT scan.

How do babies get CT scans?
The CT scanner is a large doughnut-shaped machine with a hole in the centre through which a special bed can move. The scan can last anywhere from five minutes to 20 minutes, depending on the area and complexity of the scan.

The number of CT scans required to give a cumulative dose of 50-60mGy depends on the type of CT scan, the age of the patient, and the scanner settings. If typical current scanner settings are used for head CT in children, then two to three head CT scans would result in a dose of 50-60mGy to the brain.
How do they sedate babies for CT scan?

How much radiation do you get from a CT scan?
Each CT scan delivers 1 to 10 mSv, depending on the dose of radiation and the part of your body that’s getting the test. A low-dose chest CT scan is about 1.5 mSv. The same test at a regular dose is about 7 mSv.
Is CT scan harmful?
Are There Any Risks? CT scans use X-rays, which produce ionizing radiation. Research shows that this kind of radiation may damage your DNA and lead to cancer. But the risk is still very small — your chances of developing a fatal cancer because of a CT scan are about 1 in 2,000.
Is CT scan safe for 10 year old?
“No patients should be exposed to more radiation than they need at any age,” says pediatric radiologist Marta Hernanz-Schulman, MD, chair of the American College of Radiology’s Pediatric Imaging Commission. No doubt: X-rays and scans can be helpful, even life-saving.
What can a CT scan detect in the head?
CT scanning of the head is typically used to detect:
- bleeding, brain injury and skull fractures in patients with head injuries.
- bleeding caused by a ruptured or leaking aneurysm in a patient with a sudden severe headache.
