What are the risks of a CT abdominal scan for a child? A CT scan uses radiation. Repeated exposure to radiation raises a person’s risk for cancer in the future. The CT scan should be done with the lowest possible radiation dose needed for the images to diagnose your child's problem. Children are more sensitive to radiation than adults.
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. The same dose to red bone marrow would be produced by five to 10 head CT scans, using current scanner settings for children under age 15.
However, if the CT scan examines the abdomen or pelvis area, then there may be a very slight risk to the baby. An unborn baby exposed to CT during pregnancy may have about a one in 1,000 greater chance of developing a cancer as a child.
The level of risk associated with a CT scan is not only related to the level of radiation dose, but also to the child’s age and gender. In general risks are lower the older you are. Responding to radiation risk The CT scan settings can be adapted for children (i.e. “child-sized”) to obtain the necessary information with
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.
the available research indicates that there may be some risk and the risk may be cumulative. How can we minimize radiation risk to my child? There are ways to ensure that your child is exposed to the smallest amount of radiation possible during an imaging study. The Image Gently Campaign is promoting optimal scanning strategies for children and ...
25 Απρ 2022 · In radiography and computed tomography (CT), the risk of childhood cancer induction is very low if imaging is above the diaphragm or below the knee. If intravenous contrast agent is used in CT, test thyroid function in the child after birth via heel prick.
