Can head CT scans in an infant cause radiation and learning disabilities?

Not exactly. A ct is by definition 'radiation', since it is a series of xrays computer reconstructed as sliced pictures of body tissues. It doesn't cause radiation but exposes the person to radiation. Modern ones may expose one to an amount similar to a transcontinental flight over the usa. Repeat exposure is a current topic of concern, but no specific learning disorder has been identified as connected to this.
Yes and No. Yes the ct scan is a radiation exposure but if done properly it is a low exposure.But it is always of some concern. But no there is no association to common ct exams and learning disabilities.

Side effects of CT scan for preemie infant include radiation and learning disabilities?

Doubt connection. Any learning disabilities suffered by a premi that survives most likely represent factors that precipitated premature delivery & the need for resuscitation & intensive care, not the ct scan. Last year my patient, "littlest angel" (14oz @ birth) graduated from the honors program at baylor in 3 yrs.It didn't slow her down. She never got real tall but she is quite a survivor. Read more...

Newborn son had two head CT scans done 1 month apart. At time we were unconcerned about radiation but now what is the risk of future childhood cancer?

Still very low. Yes your child has had significant radiation exposure. And yes you should always ask if additional ct scans really need to be done, or are there alternative ways such as head us or mri. That being said, the risk is still extremely low. When you are talking about a condition that is very rare, even increasing the risk 2-3 times baseline still makes it a very rare occurrence. Read more...

Child had 2 separate head CT scans as an infant, now healthy 6 year old. How concerned should we be about increased risk of cancer as a child?

Stop worrying... ... And be effective. The slight increase is real but there is not a thing to do about it, and ct's that get ordered appropriately in children are worth the tiny risk. Plan for your child to have a normal life, teach him/her the social and job skills that tomorrow's competitive world will require, and create a winner rather than a worrier. Read more...

Child had 2 head CT scans as an infant, now is a healthy 6 year old. Should we be concerned about increased risk of childhood cancer or lifetime risk?

Probably not. If you or your child's doctor are able, ask the radiology group where the ct scans were done about the dose of radiation. Higher radiation doses are associated with better resolution of the ct images, and so children's hospitals struggle with the trade off between radiation and great images. Likely your child's risk of cancer from the radiation of 2 scans is low. Read more...
