Is CT scan safe for infants?
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. CT scans are expensive.
How do they do a CT scan on a baby?
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. Although the bed will move through the scanner, it will not come into contact with your child.
Will my child get cancer from a CT scan?
The risk of getting leukemia after a head scan, the most common form of CT for children, is about 2 per 10,000 scans for children under age 5, the study found. Doctors have long known that X-rays cause cancer and that children face a greater risk than adults.
Do they put babies to sleep for CT scan?
Usually you do not need to do anything special to prepare for the CT scan. However, some children need medicine to help them sleep (sedation or general anaesthetic) so that they can lie still for the scan.
How long does a CT scan take for babies?

How can a CT scan affect pregnancy?
Ionizing radiation from CT may result in teratogenic effects to the fetus at high doses up to 15 weeks postconception. A CT scan that does not include the gravid uterus in the field-of-view results in negligible fetal dose and may be performed in pregnancy without risk to the fetus.
What happens if a child is exposed to radiation?
Children are at a greater risk than adults to develop cancer after being exposed to radiation. Increases in the rates of leukemias and thyroid cancers associated with childhood exposure to radiation from A-bomb explosions, nuclear power plant explosions, and medical procedures have been well documented.
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. The more CT scans you have, the more radiation exposure you get.
Why do you have to drink water before a CT scan?
Preparing for a CT scan
The water hydrates you prior to having contrast media for the CT. In the waiting area you will be asked to drink another 500ml of water which outlines the stomach and bowel clearly on the scans. The water also helps fill your bladder so that it shows on the scan.
