How much radiation is in a pediatric CT scan?

CT Radiation Risks in Children: Need for Concern Depending on the machine settings, the organ being studied typically receives a radiation dose in the range of 15 millisieverts (mSv) (in an adult) to 30 mSv (in a neonate) for a single CT scan, with an average of two to three CT scans per study.

How many children get CT scans?

About 7 million CT scans are done on U.S. kids each year. And that number is rising about 10\% per year.

How does radiation affect a child?

The main risk of radiation exposure is developing cancer later in life. Researchers still aren’t quite sure how much radiation exposure raises your child’s future risk of cancer. For most children, radiation exposure to X-rays probably only raises their risk of cancer a very small amount, if at all.

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.

Is CT scan safe for girls?

For girls, 1 in 300 to 400 abdominal scans would cause a solid cancer later in life. For boys, the number is 1 in 700 to 800. 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.

Is a CT scan safe for a child?

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.

Are CT scans safe for 13 year olds?

Use of CT scans has doubled for children under five and tripled for older children. Doctors are prescribing too many CT scans for children, a study says, even though they know that the radiation used in the tests increases children’s lifelong risk of cancer.

Are CT scans worth the risk?

CT scans are generally worth the risks associated with radiation exposure due to its multiple benefits. It can help spot dangerous health issues before it is too late and find the treatment that works.

Do CT scans increase the risk of cancer in children?

The first study to assess directly the risk of cancer after CT scans in childhood found a clear dose-response relationship for both leukemia and brain tumors: risk increased with increasing cumulative radiation dose.

Can CT scans predict leukemia and brain cancer in children?

The risk of leukemia and brain cancer was highest from head CT scans for children younger than 5, according to the study authors.

Can a child get radiation poisoning from a CT scan?

Children may receive a higher radiation dose than necessary if CT settings are not adjusted for their smaller body size. As a result, the risk for developing a radiation-related cancer can be several times higher for a young child compared with an adult exposed to an identical CT scan.

How common is cancer after a CT scan?

For girls, 1 in 300 to 400 abdominal scans would cause a solid cancer later in life. For boys, the number is 1 in 700 to 800. 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.
