Children's CT radiation safety knowledge that parents should know

Take your child to the hospital to see a doctor. When the doctor said that you would do CT for your child, parents would worry about radiation, which would be harmful to the child. What should they do?

CT is not the first choice for children to diagnose systemic diseases, but if it is necessary to do CT examination, what should we pay attention to?

What is CT?

CT is X ray computed tomography, which uses X ray to analyze a work of the human body and obtain a cross-sectional or three-dimensional graphic image of the part of the human body being examined.

CT can provide complete three-dimensional information of the examined part, so that organs and structures can be clearly developed and lesions can be clearly displayed.

Does CT have radiation?

CT is a valuable diagnostic and analytical technology of medical imaging, but it will also bring X-ray radiation risk to the examinee while providing medical images required for the diagnosis system of related diseases.

Therefore, while making full use of CT diagnostic technology, we should also pay attention to the impact of ionizing radiation on human health, especially children are more sensitive to the health hazards caused by ionizing radiation than adults.

In recent years, WHO, IAEA and other international organizations have also called for the protection management of Chinese children in the technical examination of radiation diagnosis and treatment.

Why should I do CT?

In clinical medical practice and examination, doctors and medical imaging technicians will judge whether children need CT examination according to the "three principles of radiation protection".

If we can use some other non X-ray inspection technology to replace CT inspection, analysis and inspection shall be carried out without using CT method as far as possible.

But each image has its advantages and disadvantages.

The advantage of CT is that it is fast in examination. For some students with acute, critical and severe diseases, CT is still the first choice of examination technology.

It is important to understand that the "benefits" of CT outweigh the "disadvantages" of the radiation you receive.

There is no absolute good or bad, only the advantages and disadvantages. Choose the most appropriate treatment at the moment.

Children should pay attention to the following when performing CT examination!

When receiving CT examination is unavoidable, we should consider how to make necessary radiation protection for children receiving CT examination.

Wear personal protective equipment for your children, such as head inspection, lead rubber neck covering to protect thyroid gland from radiation, trunk supervision and inspection, lead rubber gonad protective apron to protect sensitive parts such as gonads;

Try to avoid repeated CT examination in a short time.

Medical information imaging technicians will also adopt appropriate exposure parameters according to the physical structure characteristics of Chinese children, so as to reduce the exposure dose of the examinee as much as possible.

If a child needs our support and help in the process of receiving the inspection, the parents should also correctly wear protective equipment and protect themselves.

Let's work together to do a good job in radiation protection and ensure the safety and health of children!
